Infected with Jenxcus.K

Hi, fumagawa is here.
I got this problem since the end of April, and I think it’s pretty troublesome.
I believe my computer is infected by Jenxcus.K virus. Because all data in every flashdrive that is connected with my computer became shortcuts.
MS Security Essentials detected it as Jenxcus and cleaned it, therefore the virus is gone as well as all the data. (but maybe they’re all hidden)

I need help to solve this issue, as soon as possible, because I’m working as internet cafe operator. People are usualy visiting my workplace to print documents, print photos, scanning documents, and then store them in their flashdrives. But I’m aware that my computer is also infecting their flashdrives as well.

I really don’t want to dissapoint them, because thier visit = my income.

Much obliged.

I’ve also attached several logs required to assist this cleaning.

Please notiy me if there is something missing with the logs. I will redo all the scans.

Hi,

remover notified. Download MCShield (http://www.mcshield.net/download/MCShield-Setup.exe). Run and attach AllScans.txt. Thank you.

Your Infection… O4 - HKLM…\Run: [yxemiymdfm] wscript.exe //B "C:\DOCUME~1\TYANTO~1\LOCALS~1\Temp\yxemiymdfm.vvv.vbs

There’d be some assisiocated VBS files. That’s just a run key.

And I just thought that I’d be missing some logs. Here it is…
Thanks for your quick reply.

Oh. Sorry. I didn’t clarify that too well. It’s getting late here.

Can you plug in your infected flash drive and then scan it? Then, leave the flashdrive alone so no no one else is infected.

Here it is…

Alright, here’s what I found.
the AntiVBSBVBE ran smooothly, I’va attached the log.
However, the AdwCleaner, did not. My AV detected the software as a Malware. Weird. So it got terminated by the AV.
And the last ones, the FRST.txt and the Addition.txt …

Last night, my friends helped me to fix the issues. He went through msconfig and disabled what you guys found as the source of the threat. It worked, really.
But when I turned on my PC again, there’s only one Startup thing in msconfig that is similar with previous threat. The extension (or whatever the name) is yxemiymdfm.vvv. So I disabled it again, and my computer asked to get a restart so the change will take effect.

Do I have to delete the registry of yxemiymdfm.vvv? If that so, how to do it? I’m not that good with those things, deeply sorry.

Download attached fixlist.txt on the same location as FRST (otherwise the fix won’t work)
