Having had a bad virus infection earlier this year, I now have a number of anti-spyware and anti-virus applications on my PC, and I'm not sure that I need all of them.
In particular, I'm thinking of getting rid of Microsoft's Anti-spyware product, which doesn't seem to understand the instructions I give it, and McAfee's products - I have their Firewall, Virus Scanner, Privacy Service and Security Centre - because they seem to be hogging the processor. All of these are always running in the background.
I also have Spyware Blaster which I think also runs in the background, and instead of IE6, I'm now using Firefox, which has some built-in protection but I'm not sure if this is a Firewall or what.
From time to time I also run SpyBot Search and Destroy, Ad-Aware SE Personal and CW Shredder.
I want to make sure that I still have full Firewall, Virus and Spyware protection in place. If I get rid of McAfee and Microsoft, but keep the rest will I still have the protection I want? If not, can you tell me what am I missing, and what I can replace it with?
