I'm unable to remove "Adware" in the C:\_Restore\Archive\FS*.CAB files.
McAfee reports that these so-called "Adware" files are not trojans, viruses,
or worms.

First of all, should I trust this answer?

I must have accepted some Adware as part of a freeware/shareware software
package that I've since deleted. I've deleted the program but I have a few
stubborn "Adware" CAB files that cannot be cleaned by McAfee. Anyone else
have this problem?

Second how do I get rid of these so-called harmless files?

Thanks in advance,
