I have been running Prevx on my second PC behind a router with only SpywareBlaster and WFW since Christmas without picking up any nasties. My teenage children also use this PC so the set up has been used in a 'normal' family set up. To check, I have run the online scanners from Kaspersky and Bitdefender. I have also used Superantispyware on demand only. If this set up is secure on this PC I will be using it on my main machine. To be honest it is a good feeling to realise that the PC is not just a test bed for a number of anti malware programs. Just thought I would share this with you. Regards.
