What happened to my OS?

I used anti-spyware software Ad-ware to scan my OS. Below is the log:

Vendor:Windows
Category:Vulnerability
Object Type:RegData
Size:6 Bytes
Location:exefile\shell\open\command "" (%1 %*)
Last Activity:2005-4-28
Risk Level:Low
TAC index:3
Comment:Possible virus infection, executable file extension compromised
Description:General Windows Security Issue. Your system security may be
compromised. The specifics of the possible compromised item are listed in
the comments section.

I have fixed the problem with the software. But what confused me is what and
when caused the problem?

Thank you.
