Noticeably slow startup on browsers, Firewall not working.


Recommended Posts

Whatever this thing is it's running circles around malwarebytes that it has found nothing on top of acting wonky even after a fullscan.

Sadly this occurred at the same exact time as those "malwarebytes not opening proper" and "tray icon not showing up" issues started coming in enmasse around 8-8-2020 on the forum making me believe it was a false positive.

-Origin is most likely from malicious gelbooru ads around the time of 8-7-2020 (Sadly I did not get the memo that the current administrator is a scumbag who collaborates with malicious "ad" services when I went back there for the first time since about a decade to look for an old joke picture for someone) Completely bypassed both noscript and uBlock Origin.
-All browser-type connections sluggish and do not load initially, game internets work fine (as fine as they normally do at least) quite noticeably sluggish internet on browsers that lasts roughly about 2 minutes or more, and only on the initial starting portion of the browser. Afterwards it seems to work just fine as long as I don't close and reopen it in which the issue repeats itself.
-Browsers effected Includes: Firefox, Steam, and IE
-Other symptom:
Attempting to access the windows firewall via clicking on it via search from the control panel makes the window explorer "not responding" until I click the x off.

-Having just activated

steps taken:

-Malwarebytes fullscan has found nothing and is likely compromised by the fact I recently activated a burner e-mail so I could turn its premium functions on (I dare not log in to my actual e-mail with this thing ongoing).

-Activating premium functions has caused it not to open now, apparently the cause does not fear the regular/scheduled scanner, but will shutdown active defense. I have not restarted since this has been done.

-adwcleaner 8.0_7 only cleared out old things I never bothered with like that yahoo toolbar and other preinstalled garbage such as Cyberlink,HP, Lenovo, and WildTangent to name those.

    -I have not done the basic repair functions that accomodate adwcleaner.

    -After it did this, I noticed that my windows virus definitions had updated automatically without my input when I went to do so manually. Is this a result of adwcleaner or the malicious thing?

 -Next step will likely be FSRT64.

I restarted the computer and after running FRST it's fixed now? (Unless it comes back on restart or something)

I don't know whether FRST or Malwarebytes Premium did it on start up but here are the logs for the FRST, Regular and Addition.

Even if it's fixed, I'd like to figure out the cause and what fixed it.

Computer is running much more normally now and I have far less stress for it, I practically live on this thing.

Hello @tempburner8

The logs don't show any obvious threats at this time

You might want to run some commands to verify that all Windows system files are good.

Open an elevated admin command prompt and type in the following and press the Enter key

SFC /SCANNOW 

Then after that run the following in the command prompt too

DISM.exe /Online /Cleanup-image /Restorehealth 

Let us know what those say

Kind of a long one, do you want the entirety of the CBS.log and not just the point that it started the scan?

Figured I'd upload the full thing first, save us all some time if that's what you wanted.  Scans start around 2020-08-12 13:17:45.

I don't know enough about computers (especially since so much changes between OS versions, I came to this one from XP), so if any of these shouldn't be here/will get me haxxed or something, delete the post I guess.

Will be doing some mild browsing(Discord(Browser)/Youtube/steam gaming in the meantime, so I'm hoping neither of those things will activate a re-occurrence.

MB is running normally in premium mode now, so if that's the case hopefully it'll halt these theoretical things.

No need to review the log. The scan says it found and fixed the issues already.

Unless there is something else you should be all set

 

I'd just like to know the cause of it, Keylogger? Trojan? Bitcoin Miner? Just a weird disk error? Should I scramble to reset my passwords or something?

Maybe Malware bytes premium dealt with the problem in the background and I need to check a log for that?

The CBS log has nothing to do with any of that. It simply check to verify that all operating system files are not corrupt and are valid.

Other scans  you did before coming here should have logged and shown what was found. We can do additional scanning if you like but what has happened in the past should be in previous logs. Just open them and read them.

 

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.

Step 1:No detections

Step 2:No detections -Restarted computer-

Step 3: Giving a quick glance over, nothing really stood out to me other than those seemingly benign error messages in these logs. (Addition and FRST txts)

Will also include the first 2 logs that actually found anything, benign or not from the first time that I attempted Step 2 (AdwCleaners C00 and S00.txts):

I guess it's worth mentioning but about a month ago a "generic malware" was found in Fallout Mod Manager, but I'm fairly certain that was a false positive judging by searching around and I let it stay quarantined since then anyways as it detected an ancient exe file from 5 years ago and not the actual installation. (Keep in mind I regularly scan with Malwarebytes every night before shutdown) Can't find the log for that unfortunately to further verify that.

 

Should I do another scan with SFC and such like you suggested in your first post?

No, there is no need to run SFC again and don't need to Quote.

If you like go ahead and run these other scans to verify nothing is there.

 

Let me have you run a different scanner to double-check. I don't expect it to find anything, but no harm in checking.

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 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 bottom).
  • Press Continue when all done.  You should click to off the offer for “periodic scanning”.

 

 

Next,

 

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.

 

Thanks
