Q: i mean for free
A: Well, everyone has a different opinion... It's as if you asked 'Is Coke or Pepsi the best?' However, these are 3 highly recommended ones that you can't go wrong with...also, remember that while you can have several anti-spyware programs installed at once, use ONLY 1 antivirus or you'll be asking for serious conflicting software problems 1) AVG Free 8.0 - http://www.grisoft.cz/filedir/inst/avg_free_stf_en_8_138a1332.exe 2) Avira Antivir - http://www.free-av.de/de/download/1/download_avira_antivir_personal__free_antivirus.html 3) Avast - http://www.avast.com/eng/avast_4_home.html Hope that helps you.
