This is taken from Baserk from
www.notebookreview.com. I would say this list is probably more updated and more inclusive as it has Firewall and Malware protection:
"What is the best free Antivirus and/or Firewall and/or Anti Spyware program?"
Therefore I have made a list of these programs.
To get the best security programs (Eset or Kaspersky for instance) you will have to pay but
there are however some very good (and some excellent) programs available for free.
Almost all programs listed are available for XP and Vista, for both 32bit and 64bit versions.
These are all free programs, not time-limited trial versions.
You will have to find the right version for your OS yourself through the links below.
