Double instances of explorer.exe (vista)
 
I noticed that I have 2 instances of explorer.exe running when I took a look at my task manager.

explorer.exe 24,596K
explorer.exe 22,160K

My Computer > Folder Options > View > [ ] Launch Folder Windows in a separate process

...is already unselected by default, so that's not the problem. I have Norton 360 running at all times, and so far the only thing it has detected is Tracking Cookies, which I clean off regularly. A comprehensive scan found nothing as well. I have tried searching through google about this problem, but most of them point to the above.

Any idea whether this is indeed a known trojan, or is there some other step I can take to prevent the second instance of explorer.exe from popping up again? This is a problem for me since it seems to slow down my PC quite a bit (most noticeable when I'm playing games).

Any help would be appreciated.

Have you tried running Hijackthis and Process Explorer to see if any one of them is a legitimate explorer.exe file?

Congratulations! Looks like you caught yourself a trojan.

I suspect it would be the same one I have got, maybe a new variant of the Alureon.

Run a windows search, and the explorer.exe running under the system32 folder is the fake one. But don't remove it yet.

Download and run GMER. Disable a process that goes along <randomname.sys> to buy yourself some time.

You are still probably in the early stages of infection unlike me, so do some data salvage by burning your data onto multiple DVD-Rs (it is able to attack external HDs, even those without an OS).

Secondly, wipe any thumbdrive, MP3, PSP or any storage you have recently transferred to your PC. Don't reinstall their OS yet, leave them be.

Finally, do a format. And I mean a 100% wipe.

When you are done, quickly download or install an antivirus, and test by shifting back ONE of the files. If it is infected, you have just lost all your data like me. If not, you are lucky.

FOUND A SOLUTION (or at least for now).

I ran Microsoft Malicious Software Removal Tool in safemode, deleted my temp files (X:\Documents and Settings\XUSER\Local Settings\Temp) using Simple File Shredder, restarted my PC and ran GMER again. It is gone. I will keep updated on this.

Googled that, but it seems to be a common item found in hjackthis logs. :confused:

Its kinda weird, but I haven't been seeing this (second explorer) for awhile. I think it pops up when I open too many instances of windows folders. I did a search - there is only 1 explorer.exe found, listed under HP (C: ) > Windows.

I'm still open to any possibilities though.:eyespin:
