Here is information about that item:

I wonder if Kaspersky is finding a false positive?

C:\WINDOWS\system32\Tools\Regexe.exe <<< scan that file and delete it if bad

Thanks for the reply.

I also think it's a false positive. I checked when the file was created, and according to the file properties it was created the same date as I set up the computer. I did not have Internet access at the time.

I think the file might be part of the drivers I installed when I set up the PC. Anyway, I will run new full system scans soon. In the meantime, here are the results of the file scanners:

There is enough negative response from the scan that if this was my computer, I would delete that file:
C:\WINDOWS\system32\Tools\Regexe.exe <<< this one. You can move it to the Recycle Bin and allow it to stay there for a few days to make sure there is no negative effect on the computer, then dump the trash.

Okay, that sounds like a good idea. Though after running scans today (SpyBot, AVG, MBAM, Kaspersky online), no infections were found. Thanks again. :)
