Win32:Trojan-gen. {UPX!}

[The Mighty Yam]

Hi all,

I need some help.

My system seems to be infected with a virus Win32:Trojan-gen. {UPX!} (my Avast On-Access scanner picks it up).

The problem is that when it is detected (e.g. file name C:\DOCUME~1\MARKAD~1\LOCALS~1\Temp\winF.tmp) and I delete it, the same virus is detected again and again just in a different .tmp file.

I have tried running a boot scan and also the latest version of Ad-Aware SE. I take all the suggested action and the system appears to be clean. But everytime I open Internet Explorer, the virus is detected again.

WHAT DO I DO!!!?

Thanks in advance for your help!

(p.s. I am running Windows XP and IE version 6.)

(p.p.s. I am afraid I am not very technically minded and so I'll need straight forward instructions)

A good place to start is - Advice & Tools for virus/trojan/malware Removal & Prevention get back to us if you need more help.

Thanks... but am not getting to far...

I have tried avast CLEANER but that does not find anything while my On-Access scanner still does.

I have tried to clear all TEMP-folders (via drive CleanUp AND manually), empty Temp.Int.Files folder(s) (via IE->Extras-Internetoptions->Delete files, including OFFLINE files !!) and empty java-Cache (controlPanel -> java-Plugin -> Cache)

I have also tried disable system restore INCLUDING a REBOOT!!

Have just logged onto the internet and have Win32:Trojan-gen. {UPX!} at the location C:\DOCUME~1\MARKAD~1\LOCALS~1\Temp\win2.tmp. If I delete it, move/rename it or move it to the chest, a new .tmp file at the same location comes up as being infected.

I am slightly concerned!!!

Is your OS and Browser fully up to date with all relevant security updates?

1. The avast virus cleaner is a specialist tool that deals with a very limited number of true viruses. That is why the main scan can detect more malware.
2. Clear your browser cache and Temp folders.
3. Schedule a boot-time scan from within avast



Part of the instructions on the link I gave was for Eddy's website, I think you should visit that with a view to running HijackThis. Eddy's Website click the "HiJackThis Section" and also the "Malware removal instructions and applications" section, and follow the directions there and get back to us if you need more help....

I think/hope that I have just got this off my system, I did it by deleting, in DOS, a file named XEJHE.EXE in the root directory of the main system drive C:.   NOTE I am running W98SE, I don't know how you would do the equivalent under XP.

I discovered it via a combination of three utilities

- avast! which was reporting the problem as described above (Win32:Trojan-gen. {UPX!})

-sysinternals Process Explorer which showed XEJHE starting up & stopping and I knew not what it was

-Metaproduct's StartUp Organiser reported a peculiar new entry in the registry 3MyFqGXrc with the path to the XEJHE.EXE this was placed in Registry/AllUsers/Run, I removed this entry and then IMMEDIATELY exited to DOS and deleted the aforementioned file.

Hopes this helps, oh I suspect the filename XEJHE.EXE might be randomly generated i.e. it might be GT9JK.EXE on your system, same with the registry tag, but it was the latter with it's reference to XEJHE.EXE that confirmed my suspicions.

I am running a full thorough scan at the moment all those dodgy files in the temp directories are being picked up, but be killing the XEJHE.EXE file I think I eliminated the program that was spawning the "virus" infections into the temporary directories.

Hope this helps

Dear All,

HELP! I have disabled system restore, rebooted and run a boot time Avast scan. It was clear. I then ran another scan post boot up. It was clear. I ran Ad-Aware. Ity was clear. I ran CWShredder 2.13. THAT was clear. I ran Bazooka. That was clear. I ran Avast Virus Cleaner. Nothing there either. So then I emptied my temp files, internet history etc.# and set a system restore point.

As soon as I connect to the internet, C:\DOCUME~1\MARKAD~1\LOCALS~1\Temp\win1B.tmp is infected with Win32:Trojan-gen. {UPX!}. Whatever action I take (i.e. move it to the chest etc) another infected .tmp file takes it's place at the same location.

I am not sure if it is related but when I run task manager, I have about six versions of SVCHOST.EXE running. Is that right?

I have posted my Hijack This log in the vain hope that someone can help fix this.

Thanks. I will do that but if you think my Windows and Office are outdated... you should check out my hardware! HAHAHA!
