Help me get rid of this pls..Win32/TrojanDownloader.Zlob.BSA

I have a Dell Inspiron 9300 laptop running Windows XP home.

I'm using ESET NOD32 as my antivirus and this warning came up during a scan.

File C:\System Volume Information\_restore{202550A8-7A33-4BCA-9586-051D24DDBF8F}\RP586\A0116220.exe is infected with trojan Win32/TrojanDownloader.Zlob.BSA. The file can be deleted. It is strongly recommended that you back up any crucial data before you proceed.

Although it says the file can be deleted, the delete box wasn't clickable.

Where do I have to look for this file to manually delete it?

I've done the search for file before. Nothing came up with the whole line or A0116220.exe.

I downloaded AVG anti virus and ran a scan which came up with no issues. Then I checked with ESET and it was still there.

I did a google search for the trojan name and then I started downloading all different spyware programs that said it could find and delete them. None of them worked thoroughly. A couple of them were free downloads, and showed where the issues were but when it came to fixing them you had to buy the program.

I found a way to download through google a version of pc tools spyware doctor, but every time I run it they find new problems. At the end of the search they ask if I want to fix the infections and I say yes. Then I run the ESET anti virus program to check if the trojan is gone and it's still there.

I also use PC Checkup 3.25 and it constantly checks for issues with the computer and it finds one or two every couple of days, but with all the programs I've been trying all day there are 15-20 problems (mostly registry) multiple times today.

Thanks to anyone who can help me. I appreciate it.
