:slight_smile: Hi Fellow Believer in the Triune God :

  Nowadays "viruses" are a MINOR threat compared to "trojans, worms, keyloggers, rootkits, etc"
  so a "layered" approach is best . Definitely should use some Good & FREE antiSPYWARE/
  antiTROJAN programs, such as AVG Antispyware ( formerly called "Ewido" ) from 
  www.ewido.net and the FREE ver of "SUPERantispyware" from www.superantispyware.com .

  And hopefully you are using Good, and sometimes FREE, 3rd party software firewalls !?

  A good Resource "Guide" is the info at :
