Internet Security part 2
One of my friends told me he uses AVG free with daily scan which is overkill but allows the luxury of aborting the scan if he is working.  Next is Windows Defender also with a daily scan.  The scans never find anything so I might turn them off soon and just the let the real time protection suffice.
However there are some extra freebies which I keep on my desktop to do deeper/different cleaning:  Adaware, SpyBot Search and Destroy (one searches by file, the other by threat alphabetically!), Windows Live Safety Scan (for its registry cleaner - who better to know what to clean than the guys who built the registry), and TrendMicro Housecall which is a super deep online scan from the guys who discovered VISTA’s fatal flaw hours after it was released.
He previously did Disc Clean-up but have little to clean up now that I tweaked Tools>Internet Options>Advanced to delete Temporary Files when I close window.  So a monthly Defrag (for orderliness) and occasional Disc Check (for errors) rounds out my regimen which keeps our machines whistle clean and lasting ten years now.
