I wasn't sure where to post this question, so if I'm in the wrong spot, moderators, would you please put me in the right spot? :thumbsup:

I was going through the prefetch folder and noticed some things I knew were spyware/adware/virus related that none of the scanning tools caught, or removed. I deleted the obvious ones, but noticed that several were created near the same date that I got a bad spyware infection. Also, many of these files were created in 2005, and I've had this OS since 2003. Some I could recognize as belonging to programs I knew I had installed this year, but many weren't recognizable.

So I would like to ask: Are prefetch files "renewed" when a program has been modified, like say for instance, NAV receives updated definitions? Or are they re-written to when a program is opened (creating a modified date)? Is there someone who can look at the list of prefetch files and tell which are for bad things and need to be removed?

When a program starts automatically a copy of it is placed in the prefetch folder. This is basically a table of contents telling the cfomputer where to find certain programs so it can access them faster. You can delete anything in here without fear of problems and it will get filled again by links to programs that you run later.
