Thank you again everyone.
The only thing I really don't like about the Malicious software tool is that it goes into a sub folder and when a newer version comes out it just gets added in. From what I see, it doesn't delete the old versions which add to the clutter of files.
At least that was true in XP, I'm not sure if 7 takes the old version out.
I actually prefer to have it on the desktop in a folder where I can run it manually and then delete it when the new version comes out. I did manually d/l it & run a complete scan...you can never be too safe can you?
