Can't Remove Trojans[INACTIVE]

suzannebaer · December 13, 2007

Hello Helpful People!

AVG found several files on my husband's computer it identified as trojans. AVG would delete the files but even 15minutes later a new scan would find the same or similar files. When the problem surfaced a few weeks ago he had downloaded some new games from some different game sites. I found a reference to combofix and tired downloading and running that. It seemed to work as AVG ran clean for a couple of weeks. Now it is doing the same thing. I'm hoping you can find something in a log that can help us get rid of whatever is re-inventing those files.

Thank you for your time!

Hi,

Welcome to the site

I will be handling your log to help you get cleaned up. Please give me some time to look it over and I will get back to you as soon as possible.

I want you to show hidden files. There are instructions HERE to help you do this.

You should have Administrator rights to perform the fixes. Some of the instructions I give may need to be printed or saved for reference during the fix. Some of the fix will be done in Safe Mode so you will be unable to access this thread at that time.

Please dont use any of the tools without specific instructions. Some of them are dangerous (and could leave your computer in worse condition that it is when infected) if used incorrectly.

These instuctions should be read first, then followed. If you do not understand something, don't be afraid to ask, or see if I'm on chat.

Hi,

While TeaTimer is an excellent tool for the prevention of spyware, it can sometimes prevent HijackThis from fixing certain things.

Please disable TeaTimer for now until you are clean. TeaTimer can be re-activated once your HijackThis log is clean.

Open Spybot Search & Destroy.
In the Mode menu click "Advanced mode" if not already selected.
Choose "Yes" at the Warning prompt.
Expand the "Tools" menu.
Click "Resident".
Uncheck the "Resident "TeaTimer" (Protection of overall system settings) active." box.
In the File menu click "Exit" to exit Spybot Search & Destroy.

Please go to UploadMalware to upload a suspicious file for analysis.

Enter your username from this forum: suzannebaer
Copy and paste the link to this thread: http://www.besttechie.net/forums/Canand39t-Remove-Trojans-t13074.html
Browse for these filenames:

In the comments, please mention that I asked you to upload this file: SarahW

Hi Sarahw!

Thanks for being here to help!

I followed the directions to show hidden files and disable TeaTimer.

When I went to uploadmalware, I could not locate either of the files you requested. I tried browsing for them, typing the file names (got a message that said file not found) and doing a regular search for files and folders off the start menu.

Similarly named files existed: explorer.exe and spoolsv.exe

Is there some other way to look for them? Or should I be glad they appear to be gone?
