I have Outpost Firewall Pro 2009, avast! 4.8 Professional and I'm not sure which anti-spyware/malware should I use: SpywareBlaster ??? SpyEraser (Uniblue) ??? or SpyHunter ??? I know that I can use more than one anti-spyware software, but which one of these is more effective and which one uses less CPU? Are there any conflicts between those internet security programs..? And one more question..are Uniblue's RegistryBooster 2 and SpeedUpMyPC 3 effective? Thank you in advance!
