After Getting burned more than a few times from Viruses and Spyware, I
now update MS Windows, Use Spybot search and destroy, AVG AntiVirus
software, RegScrubXP To clean registry, Pc Doctor to check for errors
and lastly Registry First Aid. I update and Run These Every Single day.
This might seem over kill but most of the time one picks up an error
that the others Don't.
Very RARELY Do I get Pop ups and spyware.
