  1. Is this a false flag or not? Do I have some toolbar installed? Firefox.zip
  2. I installed the Malwarebytes Firefox Extension (beta) but every time i open this link rebrand.ly/advancedir which leads to my website's link https://usefulsoftwaresritesh.blogspot.in/2018/02/hey-friends-today-i-am-writing-about-my.html?zx=ee0185d9b1870d66, Malwarebytes blocks it telling that it is a phishing website. Very bad experience. You can download the screenshot from https://transfer.pcloud.com/download.html?code=5ZFFam7Zlx0spK89OqfZEeaLZMU0SDCihREHg3UVTbyQeYJBlhjCy.
  3. The Firefox addon is saying that malwarebytes forum is malicious. Maybe fix it?
  4. Hello, is this extension of Malwarebytes for Firefox true? https://addons.mozilla.org/en-US/firefox/addon/malwarebytes/ I did not see any announcements here in the forum, so I found it strange
  5. It started showing up yesterday on Malwarebytes. I noticed on Firefox (I don't have chrome), Bing was coming up as my default homepage even though I never selected that. I've used MWB and Adwcleaner to remove PUP.Optional.Conduuit but it keeps coming back. malarebytes.txt AdwCleaner[S0].txt
  6. While browsing with Firefox recently my browser was "hijacked" by an apparent tech scam page. I've included a pic of the page in question. Not being the most tech savvy person, I hit "ctrl alt delete" to get out of the page without clicking on anything. In my limited "wisdom" I decided to go into my history and cookies and delete files as well as uninstall firefox in hopes that would remedy the situation. When I reinstalled firefox, the "hijacked" page came back. I tried looking for help from the mozilla forums and was directed here for further assistance. Again, I'm not too knowledgeable with all this stuff, so I apologize in advance if I forgot to include critical information and or have trouble understanding your advice. Thanks for any help you can provide. Addition.txt FRST.txt malware file.txt
  7. I installed (what I thought was free mb) a few months ago and everything was fine. Except I was somehow treated to a trial version of Premium. A week ago I got the first firefox crashed tab. and a pop up from Malwarebytes exploit encountered. Then almost every session it crashed. Then ie started crashing. COMON DENOMITER MALWAREBYTES. I uninstalled mb and returned to normal. Decided that it was the premium mb . and an hour ago installed mb FREE???? again. Saw the premium trial message again and opened firefox IMMEDIATE TAB CRASH. If this is how you treat you Premium customers. I DON'T WANT TO BE ONE.... BYE
  8. I've been using MBAE Beta for quite some time with no ill effects. Lately, however, I started experiencing a problem with Firefox. Sites would not open in new tabs, whether I opened a tab first and used a bookmark or typed in an URL or right-clicked on a link and selected "Open in new tab." This behavior was erratic -- sometimes sites would open and sometimes they would not, but mostly, sites would just not open. I tried the usual Firefox troubleshooting: started in FF Safe Mode; uninstalled all add-ons; cleared cache and cookies; refreshed FF; uninstalled FF and downloaded and installed a new copy. Nothing worked until I realized that although MBAE is not an "add-on" per se, it was starting with Firefox, even in FF Safe Mode. I disabled MBAE and the problem seems to have gone away, although it's been less than a day and I'm still testing. I don't know exactly when this behavior started, but it's currently happening with Firefox 58.0.2 (64) running on Windows 7 Pro x64 (uptodate with all Windows Update patches).

  9. Hi, I'm having the same issue as the user on this thread: I've tried rkill, hitmanpro, adwcleaner, etc. The only program that sees it is malwarebytes, but after I quarantine and remove, it pops up again just as described in this post. I already downloaded the Farbar recovery scan tool. Thanks for your help, Eric
  10. Dear all, since a few days the MB is blocking an shutting down FF after a few seconds, sometimes minutes. I didn't found any trigger event for this.

  11. I installed Malwarebytes on my android phone, using recommended settings. No malware found. I had been using Firefox and Chrome. Now neither one functions. I can still make calls. Appreciate any replies, no comment is too basic....
  12. Firefox Quantum Beta (v. 58.0b4, 64 bit) was being automatically closed by Malwarebytes (v. today. I had it do this multiple times today, every time with completely different websites open, it's not any specific website. I have a screenshot of the popup attached. I also have a screenshot of how it's impossible to add any exceptions for exploits in Malwarebytes as it won't allow me to select any, there's NO LIST to select from. The Malwarebytes pop up says: "Exploit automatically blocked Malewarebytes detected and blocked an exploit. It is no longer a threat. Affected Application: Mozilla Firefox Protection layer: Protection against OS security bypass Protection Technique: Exploit ROP gadget attack blocked." Additional information: Malwarebytes version information: Version Component package version: 1.0.236 Update package version: 1.0.3287 In Firefox, I have a few add-ons/extensions: Cisco Webex extension v. 1.0.12 Lastpass free v.

  13. Two weeks ago I updated FIrefox to the latest- and got some malware bytes warnings. I''m sure I downloaded from a safe location. I uninstalled and tried to install again and got warned I was not running win 7. Tried to install the previous version that I had been running - same warning - had to copy a backup version of FIrefox. Several attempts to reinstall - all failed. However it seems to have updated by itself, Yesterday tried to install an update for SyncBack Pro - it worked but warned I was running WIn XP. I'm running WIn 7 Professional 64 bit - thats what shows under computer properties Otherwise everything works
  14. Hello, I'm new to the forum so excuse if this post is not in the correct place but i really need some help on this one.. My fathers computer has been running terribly slow and he says it's been turning off and restarting and just acting strange. So i figured i can run malwarebytes + other virus scanners, CCleaner, clear his cache and cookies and web history and i figured that would do the trick but after i did all the troubleshooting, the same symptoms are appearing. So i pulled up netstat and I found out his computer is connecting to pornhub.com via firefox sessions( which aren't open) and 1sass.exe appears to be the one that's opening them? I've tried scanning with multiple antivirus programs, tried different firewalls. I tried going through command prompt to delete the file but it woudln't allow me to do so. I've attached a screenshot. What should i do? Thank you
  15. I have a user running Win7 Pro 64. They are continually being directed in FireFox to a fake "your computer is infected site" I have run a full Avast scan - no items found A MalwareBytes scan - nothing found Windows Defender - nothing found FF has no add-ins or extensions completely deleted their FF profile Done a system restore back as far as possible I cant get a clear answer from the user if it will happen when FF is not running (I think it has to be open, but could be in the background). I myself have clicked on a totally clean link and been redirected to the "your infected" page, but as I said I think FF just needs to be open, no link click necessary. All startup programs and services are legit The URL to the site is a very long string: h t t p : //code-ss57.stream/guest/01234567891011121314151617181920212223.... Any thoughts, or help would be appreciated
  16. Hey guys I got notified on mbam that a update.exe was trying to connect to a porn site specifically jdsr16888.info And I removed it and it was in the appdata location and it had like a Firefox logo and Firefox files when I never installed it what do I do?
  17. 2 threads I found were closed with no real resolution posted. Win7 64 bit reinstall(hard drive failed 2 weeks ago). Malwarebytes and Symantec find nothing. Doesn't pop up all the time. Only vulnerability I can think of is before the reinstall and after my laptop guy had me lower the whole way to make my wireless printer work. After he reinstalled win7 64 bit pro I had to do the same thing to get the printer to work. Control panel, user accounts & family, user accounts, change user account controls setting, has to be lowered the whole way in order to use my wireless HP printer. So now it will never notify me about changes to my computer. Firefox updated to the latest. Don't use IE or Chrome but may have when downloading HP driver or something that may have launched one of those browsers . laptop still usable, definitely occasionally annoying, but no idea of what other intrusions could be happening. Assistance please - or point me to a thread that has a successful resolution posted. I updated Malwarebytes last night and reran it but I will do it again tonight. Hoping that it will now find this redirect. Thanks!
  18. FYI, having a similar problem when trying to open either Chrome or Firefox. Error: "Exploit ROP gadget attack blocked" Latest version of Malwarebytes (just installed today), Chrome, & Firefox. Discovered that if I UNCHECK "CALL ROP Gadget detection (64 bit)", under Browsers & Chrome Browswers, I can launch Chrome & Firefox. Note: Screen shot shows what the default was before I unchecked them. @vbarytskyy Do you want me to do the same thing you recommended in #8?
  19. I was having problems with website loading and memory abuse with my upgrade to Firefox (FF) 57, so I tried the beta; still had problems. I posted to the FF forums and was advised to uninstall, delete directories, and reinstall 57 from a verified Mozilla link. I deleted everything, including folders in AppData, then reinstalled, after verifying that it did indeed direct me to https://www.mozilla.org/firefox/all Upon starting the newly installed FireFox (where "installed" includes the automatic running of FF synch - I am not absolutely positive, but I believe the mal-behavior only started once I had entered my credentials into FF synch) I was inundated with malware in my browser (some example screenshots are attached hereto). One screen claimed it was from Windows Defender stating that I had the Zeus virus and provided a phone number to call for help (I apparently am stupid, but not that stupid). On most of my synchronization restorations, the main portion of the top one fourth of my screen showed an unfamiliar button to "Start" my re-installations which I also note does not show if I go to those sites now. These redirected me to multiple CrapWare sites. That shot of "From Doc to PDF" screenshot was one of the CRAPware sites. The FoxClocks site shows the unfamiliar button which appeared on most of my screens during the update to synched addons, the Office Works screen is another CRAPware screen, and the last is the spoofed Defender Zeus infection claim. The MalwareBytes report and FRST scan reports are attached. As it might be relevant, I have also included a list of the shown addons from FF (due to my suspicion that the behavior might have started when this version of FF started synching with the other computer). I do use Defender for normal daily AV and Malwarebytes Premium. I subsequently also ran Eset's online scanner, AdwCleaner, HitmanPro and SpyBot. Nothing was detected other than minimal threats such as cookies. Thank-you very much for your expertise. This has me very confused for normally I am paranoid and have rarely knowingly run into this kind of problem except when a daughter (I have four) have used my computer and did something against my typical warnings. What is just as strange is that this specific behavior has never happened prior to the re-installation of FF and since the initial event has never occurred again to any degree.

  20. Starting on Friday the 13th, I've been having a lot of trouble. I suspect a virus. The first problem I noticed was with Firefox, my default browser. It would not launch. When I look in Task Manager only about 8000kb loads into memory and then it chokes. Sometimes if I reboot I can get Firefox to open. But if I click the wrong thing it hangs or freezes. Once that happens Firefox is "tainted" somehow and it gets stuck at around 8000kb no matter what I try. Once this happens I can't get my back-up browsers (Chrome, Opera, etc.) to launch either. While struggling with that I found that I couldn't read a PDF nor could I launch MS Word. I haven't tried every single program but since the ones I use every day are crippled I'm essentially out of commission. I regular use Malwarebytes Anti-Malware Home Premium, plus Malwarebytes Anti-Exploit Premium. I also have Webroot Secure Anywhere as my anti-virus protection. Since this problem I have run Rkill, Spybot Search & Destroy, SUPER Anti-Spyware, Kaspersky TDSSkiller, Kotver remover, Farbar, and maybe some others I've forgotten. I have scanned multiple times and have found some supposedly malicious files. But after deleting them the problem persists. In other words, I've tried everything and after 6 days I'm at the end of my rope. I guessed that my .EXE file associations may be corrupted by the virus so I used a fix from Doug's Windows Tweaks & Tips. It seems to restore the registry and things work for a little while. Then Firefox freezes and I have to reboot and start over. The thing that seems to cause the freeze is opening a new tab. Also, if I click a hyperlink in an email Firefox will crash. Copying and pasting the URL seems to be okay, but clicking the link isn't. I hope that's a clue. I use Roboform with my browsers but other than that there's nothing fancy added. I'm attaching my Malwarebytes log as well as the two files generated by Farbar. Any ideas? Thanks in advance! Dave Addition.txt FRST.txt Malwarebytes log.txt
  21. I really need help getting rid of a pesky virus, HKU\S-1-5-21 I scan my computer and it's there. I get rid of it, and a few days later, it comes right back! I don't know how to completely exterminate this thing! I'm sure its causing me the problems I've been having with my PC. I'm using a Student account, and yet some programs ask me to give permission to run with the little admin shield symbol. Also, my Mozilla Firefox bookmarks, history, ect. will sometimes stop working, and that red bar will appear at the top of Firefox telling me it can't access my bookmarks because they're being accessed elsewhere. Also, the Malwarebytes taskbar logo disappears when my computer's acting up like this, and I click to open Malwarebytes and it doesn't open. I then go to the Program files of Malwarebytes and it tells me I don't have access. It also tells me I don't have access when I try to uninstall MBAM. *Note: A bit (a few weeks) after I logged into the Admin account on my PC and changed a registry file to make a game that wasn't working on my PC work, and I updated my PC, this all started. I don't know if there's any correlation between the two events, but my computer was fine up until that point. I changed: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SubSystems\ SharedSection=1024,3072,512. Change 3072 into 4096 so it reads: SharedSection=1024,4096,512 Here's the scan log for the virus: Malwarebytes www.malwarebytes.com -Log Details- Scan Date: 12/16/17 Scan Time: 11:39 AM Log File: af1cae6c-e27f-11e7-908c-e4115bfc336f.json Administrator: Yes -Software Information- Version: Components Version: 1.0.262 Update Package Version: 1.0.3501 License: Premium -System Information- OS: Windows 7 Service Pack 1 CPU: x86 File System: NTFS User: Student -Scan Summary- Scan Type: Threat Scan Result: Completed Objects Scanned: 243651 Threats Detected: 1 Threats Quarantined: 1 Time Elapsed: 45 min, 6 sec -Scan Options- Memory: Enabled Startup: Enabled Filesystem: Enabled Archives: Enabled Rootkits: Enabled Heuristics: Enabled PUP: Detect PUM: Detect -Scan Details- Process: 0 (No malicious items detected) Module: 0 (No malicious items detected) Registry Key: 0 (No malicious items detected) Registry Value: 0 (No malicious items detected) Registry Data: 1 PUM.Optional.DisableMCProperties, HKU\S-1-5-21-3769206596-2729350310-207999698-1000\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\POLICIES\EXPLORER|NOPROPERTIESMYCOMPUTER, Replace-on-Reboot, [14365], [293306],1.0.3501 Data Stream: 0 (No malicious items detected) Folder: 0 (No malicious items detected) File: 0 (No malicious items detected) Physical Sector: 0 (No malicious items detected) (end)
  22. My 77 yr old Dad bought and installed Malwarebytes Premium and since then, it blocks most webpages - won't open them. He is using Firefox. It seems MalwarePremium also deleted/stopped a XPCOM.DLL file from working. Help please? Celia
  23. Started having problems with my browser (mozilla), pages were redirecting with ugly stuff. Checked, no new or suspious add-ons, or toolbars. Made research. First, made a scan with Windows Defender, nothing showed up. Then, I made a scan with Malwarebytes free trial, detected 2 hijacks: PUP. Optional. FFHijacker. were on quarantine and then delete it. Everything was fine, while i continued to make my homework, the websites were redirecting again, luckily malwarebytes blocked them. I ran another scan and it came clean, but the problem of pages redirecting persisted. Then I ran a scan with Adw Cleaner and found 13 threaths, the I proceeded to clean, and reboot. Ran CCleaner. Problem still there. I ran a third scan with Malwarebytes and new threat showed up: Malware. HackTool. File Patch. I don't know what to do anymore. Ps. if helpful, I saved the reports on both, malwarebytes and adwcleaner. report.txt AdwCleaner[C0].txt
  24. After a few seconds of Firefox beta 58b4 opening, Malwarebytes closes and blocks with this message: protection against OS security bypass exploit ROP gadget attack blocked had to uncheck "RET ROP Gadget detection (64 bit)" for "Browsers" to keep this from happening. I always run Firefox beta and this just started after the upgrade to v58b4. This was not happening with any of the Firefox beta 57 builds. I've ran Firefox in safe mode with add-ons disabled with the same result. Also, this happened before and after the most recent upgrade to Malwarebytes. Malwarebytes - updated MB db as of 10:39am EST Windows 10 (Build 16299.64) Firefox beta 58b4 malwarebytes-report-17nov2017.txt MBAMSERVICE.LOG
  25. I updated successfully to the new Malwarebytes consumer (premium) on M$-Windows XP SP3 32-bit, but Firefox ESR 45.9.0 and Thunderbird 52.3.0 would each fail to start, presenting the window offering to submit a crash report (to Mozilla). Google Chrome 49.0.2623.112 and SAS 9.3 both started and ran fine. I tried turning off Malwarebytes protection features, one-by-one, even turning off protection specifically for Firefox. The only way I could restore functionality for Firefox and Thunderbird was to remove Malwarebytes and reinstall Malwarebytes (premium). I upgraded Malwarebytes to the latest version on a Windows 7 laptop. It works fine, but does not have Thunderbird. Thanks for any suggestions
