Unable to install malwarebytes

[dejavu]

My laptop restarts after I start installation but I'm met with a "An error has occurred and Malwarebytes will not install on your computer" message. I've tried using the support tool to clean and reinstall Malwarebytes but that didn't work out either. Attaching the required logs.

Hello @dejavu and

Thank you for attaching the MBST-Grab archive but unfortunately it was unexplainably incomplete. As an alternative, please follow the procedure below and attach the two (2) resultant text files in the manner you used in your first post:

Please download the 64-bit Farbar Recovery Scan Tool and save it to your system's desktop.

Note: You need to run the 64-bit version to be compatible with your system.

You can check here if you're not sure if your computer is 64-bit.

• Double-click to run it. When the tool opens click Yes to the disclaimer.
• Press the Scan button.

• It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
• The first time the tool is run, it also makes another log (Addition.txt). If you've run it before it may not and you may need to select it manually
• Please attach both logs to your reply if possible. Otherwise, you may copy/paste the logs directly if you have to, but an attachment is better.
• To save attachments please click the link as shown below. Then browse to where your file is located and select it and click the Open button.

After those two reports have been thoroughly analyzed, a Malwarebytes staffer, or qualified expert volunteer, will reply and work with you for resolution.

Thank you.

[AdvancedSetup]

Hello @dejavu

The computer is infected. Please run the following fix.

 

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.
NOTE. It's important that both files, FRST or FRST64, and fixlist.txt are in the same location or the fix will not work.

Please make sure you disable any real-time antivirus or security software before running this script. Once completed, make sure you re-enable it.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system that cannot be undone.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1:  This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. It will also run a disk check on the restart to ensure disk integrity. Depending on the speed of your computer this fix may take 30 minutes or more.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed. The use of an external password manager is highly recommended instead of using your browser to store passwords.

NOTE-3: As part of this it will also reset the network to default settings including the firewall. If you have custom firewall rules you need to save please export or save them first before running this fix.

The following directories are emptied:

• Windows Temp
• Users Temp folders
• Edge, IE, FF, Chrome, and Opera caches, HTML5 storages, Cookies and History
• Recently opened files cache
• Flash Player cache
• Java cache
• Steam HTML cache
• Explorer thumbnail and icon cache
• BITS transfer queue (qmgr*.dat files)
• Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

Thanks, I have followed the prescribed steps and restarted my PC. So how did you discover that the PC was infected? I had already run two programs (rkill and hitman pro) before sharing the reports with you but it seems they didn't get the job done.

[AdvancedSetup]

The FRST program shows what is running on the system and with years of experience one can often spot things that just don't look normal. Then research a bit to verify if normal or not and then have FRST remove such entries.

Please find and post back the FIXLOG.TXT file @dejavu so that I can verify what was completed and if there were any issues with the fix. Then we can move on from there. We're not completely done yet.

Cheers

 

[dejavu]

Fixlog.txtThanks, here you go.

[AdvancedSetup]

Thank you, as part of the fix it also found and corrected the following

Windows Resource Protection found corrupt files and successfully repaired them.

Let me have you run the following please in the exact order provided.

 

 

 

Please run the following steps and post back the logs as an attachment when ready.
Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans are completed.
Temporarily disable Microsoft SmartScreen to download software below if needed. Make sure to turn it back on once the scans are completed.
If you still have trouble downloading the software please click on Reveal Hidden Contents below for examples of how to allow the download.

When downloading with some browsers you may see a different style of screens that may block FRST from downloading. The program is safe and used hundreds of times a week by many users.

Example of Microsoft Edge blocking the download

 

 

STEP 01

• If you already have Malwarebytes installed then open Malwarebytes and click on the Scan button. It will automatically check for updates and run a Threat Scan.
• If you don't have Malwarebytes installed yet please download it from here and install it.
• Once installed then open Malwarebytes and select Scan and let it run.
• Once the scan is completed make sure you have it quarantine any detections it finds.
• If no detections were found click on the Save results drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
• If there were detections then once the quarantine has completed click on the View report button, Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
• If the computer restarted to quarantine you can access the logs from the Detection History, then the History tab. Highlight the most recent scan and double-click to open it. Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
• If Malwarebytes won't run then please skip to the next step and let me know in your next reply that the scanner would not run.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

• Double-click to run the program
• Accept the End User License Agreement.
• Wait until the database is updated.
• Click Scan Now.
• When finished, if items are found please click Quarantine.

• Press the Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.

I'm heading to lunch soon @dejavu go ahead and post logs though if you're ready and I'll check them when I get back

 

[dejavu]

Hey, as of 3 hours ago my Google account got hacked. In a matter of seconds, my 2FA device was changed, mobile number was changed and the recovery email was changed to the same email that got hacked (how is this even possible?). I also got logged out from all my devices and now they're all alien to google.  Is it likely that the malware on my system was responsible for this? Also for some reason I'm unable to launch malwarebytes. Should I try performing the steps in safe mode?

[AdvancedSetup]

Anything is possible but if they were able to also intercept 2FA that would seem they have some type of connection to your phone possibly or some other way of tricking you.

Have you scanned your phone for malware? Do you have Android or Apple?

 

 

Let me have you run a different scanner to double-check.

I would suggest a free scan with the ESET Online Scanner

Go to https://download.eset.com/com/eset/tools/online_scanner/latest/esetonlinescanner.exe

• It will start a download of "esetonlinescanner.exe"
• Save the file to your system, such as the Downloads folder, or else to the Desktop.
• Go to the saved file, and double click it to get it started. 
• When presented with the initial ESET options, click on "Computer Scan".
• Next, when prompted by Windows, allow it to start by clicking Yes 
• When prompted for scan type, Click on Full scan 
• Look at & tick  ( select )   the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"   and click on the Start scan button.
• Have patience.  The entire process may take an hour or more. There is an initial update download.
• There is a progress window display.
• You should ignore all prompts to get the ESET antivirus software program.   ( e.g. their standard program).   You do not need to buy or get or install anything else.
• When the scan is completed, if something was found, it will show a screen with the number of detected items.  If so, click the button marked “View detected results”.
• Click The blue “Save scan log” to save the log.
• If something was removed and you know it is a false finding, you may click on the blue ”Restore cleaned files”  ( in blue, at the bottom).
• Press Continue when all done.  You should click to off the offer for “periodic scanning”.

 

Note: If you do need to do a File Restore from ESET please follow the directions below

[KB2915] Restore files quarantined by the ESET Online Scanner version 3

https://support.eset.com/en/kb2915-restore-files-quarantined-by-the-eset-online-scanner

 

Thanks @dejavu

 

[dejavu]

Hi, I'm running the ESET scan and will post the log once it's done. I have an Android phone. How do I go about scanning it?

[AdvancedSetup]

You can go to the Google Play Store and look up our installer and run it.

[dejavu]

Hi, attaching a few more logs for the PC. AdwCleaner was not able to find any threats.

log.txt Malwarebytes Log.txt

[AdvancedSetup]

Please follow the directions from the following topic to clean Google Chrome better. Also, don't forget ALL devices running Google Chrome need to be cleaned

https://forums.malwarebytes.com/topic/258938-resetting-google-chrome-to-clear-unexpected-issues/

 

Once Google Chrome is cleaned well enough the Malwarebytes scan should come back clean.

If you like I can help you to fully remove Google Chrome from the local Windows computer. You'd need to export any bookmarks you want as the script would remove all.

Just doing an uninstall of Google Chrome does not remove all of it's settings. They are stored all over the computer

 

[dejavu]

I don't know how exactly the steps would vary for me. Sync for Chrome has been paused since I lost my google account yesterday so I ran malwarebytes today morning with sync effectively disabled. I'm not able to access the play store on my mobile (because it's asking me to login with the hacked google account which I can't) and I don't want to remove the hacked account from my phone because then I'd lose all the emails and photos that I can at least view on it currently. How do you propose going about this?

[dejavu]

I just followed the steps under the "Force Reset Google Chrome" section in the guide you linked. Running Malwarebytes now.

[dejavu]

Malwarebytes Log after Cleaning Chrome.txt

[AdvancedSetup]

Good, that looks good.

As far as your hacked account. I'm sorry I have no idea what the best thing to do is. You might try contacting Google Support

For the PC please run the following and choose FULL scan.

 

 

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted software from a system.

The download links & the how-to-run-the tool are at this link at Microsoft

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

Please let me know the results of this scan.

The log is named MSERT.log 

the log will be at  %SYSTEMROOT%\debug\msert.log   which in most cases is

C:\Windows\debug\msert.log

Please attach that log with your next reply.

 

 

[dejavu]

I managed to install Malwarebytes on my phone (by hitting the install button on play.google.com from my PC). The scan returned no threats or issues. I'll post the log for the Microsoft Safety Scanner once it's done.

[AdvancedSetup]

Thank you @dejavu

I'll check back on you again tomorrow.

Cheers
