Infected with malware/malvertising

[ThatThereTim]

Howdy,

So it looks like I’m infected with some adware/malvertising.

Pretty sure it was from a trainer on megagames - this'd be the first time it'd ever come from there though, in years of using that site.

Symptoms:

• Every 15-30mins, I get a browser opened to one of a few different ad sites – for the majority of them, Malwarebytes picks it up with a “Website blocked due to malvertising” notification.
• If I try to browse/search anything with “adw” or “farbar” in it, the malware kills the process for that app – this means it affects all browsers (tested with Chrome, Edge, and Opera), and even things like opening the log for adwcleaner (since notepad shows the file name in its titlebar, the malware picks this up and kills the notepad.exe process), and trying to run Farbar Recovery Scan Tool.

Things done so far:

• Updated/ran latest Malwarebytes Anti-Malware, and it does detect the malvertising going out to go.oclasrv.com (the error/warning in browser), but doesn’t seem to be able to fix it.
• I managed to get AdwCleaner installed by downloading it on another pc and copying it over (because I couldn’t open a webpage that had "adw" in the title or url as the malware kills the process), ran it, cleaned, rebooted, and it still shows as threat detected – so AdwCleaner can’t seem to be able to fix it - screenshot attached.
• I managed to get the Farbar Recovery Scan Tool on to the machine using the same method I did with AdwCleaner, and at first I couldn’t run it, as the malware would kill the process as it loaded. I noticed there were two blank processes running – one of them taking up almost 60% of CPU performance(!). I ended both processes, and was able to run Farbar – logs attached.
• Since this happened, I’ve also installed/run Zemana Antimalware (doesn’t detect the threat), and Gridinsoft Antimalware (also doesn’t detect the threat).

Attached:

• FRST log, Addition log, AdwCleaner logs, images of the blank processes, and AdwCleaner’s report.

Thanks in advance for any help. <3

Hello and

Can you run one more MalwareBytes scan and let me know if something is detected?

[ThatThereTim]

Hey @TwinHeadedEagle,

Sure, no problem! I ran both AntiMalware and AdwCleaner again:

• AntiMalware is detecting no threats on scan (2018-06-05 14_39_46-MBAM attached), but is picking up when the malware tries to browse to a url (2018-06-05 14_40_10-MBAM report screenshot attached).
• Adw Cleaner is detecting the threat (2018-06-05 14_41_33-MBADWC attached), but when I click clean & repair, and select the repair and reboot option, after rebooting it still shows the threat as detected and not removed (2018-06-05 14_44_13-MBADWC_CleanAndReboot_NotClean attached).

[TwinHeadedEagle]

Yes, there are some malware related entries in your logs. MalwareBytes is getting updated to mitigate it starting from its next database update. Now we are going to remove it manually

 

 

Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.
Running it on another one may cause damage and render the system unstable.

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

• Right-click on icon and select Run as Administrator to start the tool.
  (XP users click run after receipt of Windows Security Warning - Open File).
• Press the Fix button just once and wait.
• If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
• When finishes FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.

Good. Everything okay now?

[ThatThereTim]

Morning,

No more instances of browser opening in the last 20hrs~ and I can search/run apps with things like adw and farbar in the title - so that's all fixed! ?

AdwCleaner does still detect a threat (screenshot attached), and clean+restart doesn't fix the detection of the threat, but as there's no symptoms of it doing anything malicious I guess that's ok?

[TwinHeadedEagle]

Glad we could help.
