I use free Avast for virus, SpywareBlaster free and free Malwarebytes. I don't use the default Windows 7 firewall as I have recent heard some intrusive/daata holding things but that might all be just rubbish. I have been using free PC Tools firewall version of several years ago but again I heard they were bought over and have ties to Microsoft.
What is the best free firewall or best free internet security suite? I have read mixed reports about Comodo.
