Malware Detected: W32/Patched.UA and ZeroAccess

hekuro · Aug 5, 2012

Good morning,

I'm running Win7 64bit.

I was hit with a google redirect in firefox a week or two ago. Clicking on a link in search results sometimes redirects to 'sponsored results'. Occurrence is intermittent, sometimes going 24 hours without incident. Have not experimented much with alternate browsers to determine if problem is isolated.

I also had random sound clips playing at odd moments. Appears in the sound mixer as 'name not available.' Installed Avira, ran it quite a few times, including twice in safe mode. Quarantined 16 files, finding a few more each time. Sound bites have stopped playing, google redirect persisted.

W32/Patched.UA was detected and quarantined (filename C:\Windows\System32\services.exe.) Always detected in the next scan after reboot, however.

I followed the directions in the google redirect thread, but it hasn't been long enough to tell. Files from GooredFix, TDSSKiller & MBRcheck attached.

Additional problem of note: An older version of TrendMicro was on my computer. Apparently it did not install correctly, so it doesn't actually seem to work, and I am unable to uninstall it. FF & IE both have TrendMicro extensions that are listed as disabled, but are still blocking 'malicious' websites.

I have tried Windows Uninstall, TrendMicro Toolkit to uninstall, Revo Uninstaller, and deleting the obvious TM files directly from the registry in safe mode. I cannot remove this program. It just tells me that it cannot be uninstalled while FF, IE or Outlook are running, even though none of those programs are active. Deleting files from the registry didn't seem to make a difference. Revo is unable to create a system restore point and I am not knowledgeable enough to just delete all the randomly named registry files it found, without any way to restore.

Logs from the Malware removal process will follow in the next post, as that requires more than 4 uploads.

I then proceeded to follow the Malware removal instructions from this forum, removal of TrendMicro being the notable exception.

TrendMicro will NOT allow me to dl MGTools. Since it is not installed properly, nor can I uninstall it, I had to skip that step.

Reports from Rogue Killer, Malwarebytes and Hitman Pro are attached.
I must admit, I'm confused by the instructions:

Rogue Killer instructions say nothing one way or the other about deleting threats, so I did nothing other than save the report, despite detected registry files. The instructions for ZeroAccess removal it provided were in French and the video was too blurry for me to figure out what was being shown anyway...

Malwarebytes instructions specifically say to fix everything found. Nevertheless, the program found nothing in my case, so no action taken.

Hitman Pro instructions emphasize taking no action on found threats, so again, I did nothing but save the report.

I'm uncomfortable with these programs finding viruses, but then not being able to take action to remove them. Any particular reason why we're supposed to let Malwarebytes deal with threats but not the other two programs?

The only other error I've noticed is upon startup, I get a warning message that a "run.dll" cannot be found, or executed, I forget exactly which. It started after Avira quarantined several files.

At what point do I enable UAC again?

Thanks for the help, I appreciate all the work you are doing!

Hi Kestrel13!,

The logs are all attached. The computer seems to have been running ok the last few days, I haven't had any google redirects or random sounds playing. A few oddities like re-sized desktop icons, and not always being able to get to the Advanced Boot Options screen. But on the whole, it's been ok. So nothing different one way or the other to report yet.

Just experienced another google redirect
Click to expand...

In which browser?

hekuro · Aug 8, 2012

Firefox

Kestrel13! · Aug 9, 2012

We are going to be uninstalling your old version of FireFox (USE REVO UNINSTALLER!! See further down) and installing the new version. So do the below to save bookmarks:

Run FireFox and click Bookmarks.

Then select Organize Bootmarks.

Then on the next window click File and then select Export. Save the bookmarks.html file to your Desktop for later use in importing.

Now download and save the installer for the current version of FireFox but DO NOT install it yet. Get it here: Mozilla FireFox

You will need exit FireFox now and use Internet Explorer to continue with the below until we reinstall FireFox.

Start by uninstalling FireFox. Try Revo Uninstaller.
Choose the option on the bottom of the list (#4). Be very careful while deleting the bolded registry items ONLY!! This software will create a system restore point for you as well prior to uninstalling a software program.
Reboot. Do not skip the reboot.
After reboot, delete the below folders:

C:\Program Files (x86)\Mozilla Firefox

C:\users\UserAccount\AppData\Roaming\Mozilla\Firefox

where UserAccount is the actual user account name being used.

Now reinstall FireFox from the file previously downloaded.
Import your bookmarks file. (similar process to exporting).

Any change?

Hi Kestrel13!,

I downloaded Revo earlier, right after all the problems started, but it gives me an error message every time I try to use it: "Creating System Restore Point - failed!"

Should I continue anyway? Uninstall and re-download Revo?

Thanks,
Hekuro

Yes uninstall Revo and reinstall, then try again. Let me know what happens.
