I would keep Microsoft Security Essentials and Malwarebytes' Anti-Malware and I would add SUPERAntiSpyware. I would dump all the rest. If you do some Googling you will find many problems with and Iobit products(360 & advance sytem care). Ad-Aware and Spybot are not as good as the other free alternatives mentioned about IMO.
Can different security and ad ware protections be used together? For instance , Malawarebytes(free version), Spybot, lavasoft adware(free version), Microsoft security essentials,Iobit 360 and Advanced system care(full versions) . can they be used together. My friend has these on his computer , and out of all of them , spybot, andIobit products(360 &advance sytem care) help protect better htan the Microsoft product , and others . I sthere any advice I can give to them ?? They are using 32bit windows xp
