both in windows/system32 and in documents and settings...

I've been doing some virus fighting. I scanned online at panda and deleting the 4 files it found. I loaded Adware and Spybot.

I think I got it taken care of...for now...

This is my latest highjack log

hi. I've got the same problem with this same virus. Mine is in
C:\Documents and Settings\Administrator\Local Settings\Temporary Internet Files\Content.IE5\4TYBK527\py[1].exe

When I delete the file and then check the computer with Norton, it says no virus found. When I then turn off the computer and turn it on again, it finds the virus again, in the same place, only not in the same file (the 4TYBK527 one). Please please please, help me because I suck so much at computers and I really don't want that virus to mess with my stuff!!!

Thank you
dousugar

Howdy,

@dousugar

shut off your restore like cubsbaseball did, reboot in safe mode and scan again, all this after emptying yout temps to include offline and TIFs. It should be gone then. Smile

Question @ both of you: Do you have an Nvidia Graphics Card?

Hold on a second, I'm RRRReally bad in computers, so what is restoring? And what is Nvidia Graphics Card?

Thanks!!! Smile

mrrockford,

I do have an Nvidia GeForce2 MX400 graphics card. Why do you ask?

Again, I think I cleaned my system of this backdoor.trojan.

The reason I think so is because when I had it my Explorer would only give 404 not found page when my Norton Internet Security was enabled. Explorer would only work when disabled Norton Internet Security. Now that is not the case. My Explorer works fine with Norton Internet Security up and running.

If it comes back I'll post again.

Thanks.

Howdy,

@dousugar,

Read through this and it will help you learn about the Restore function.

http://service1.symantec.com/SUPPORT/ts...ec_doc_nam

Check the book that came with your comp to see what Graphic Card is in your machine

@all,

I have noticed that several people have been having problems with NIS(and other AV's) that have Nvidia GC's with older drivers. Don't know if it really works(I have ATI) but some have reported better results after having updated to the newest driver version.

your executables may be returning because there has been an entry included in your startup registry. Even if you delete the files, they will return when you reboot. It can be a little tricky, but you can check your registry using RUN...."regedit". Follow the path HKEY_Local_Machine\Software\Microsoft\Windows\CurrentVersion\Run
Now double click on Run. The right side panel will show a list of programs started on startup. There may be a reference to your virus executable file in there. (Mine was in "Load32"). If there is..you can delete it. Warning ....be careful not to delete a valid file...you can do harm to your computer. Make sure whatever file you delete is not one you need.
