Spybot vs. McAfee

[dlewk]

Hello, I need some help here. I'm not real computer savvy but I believe my McAfee anti-virus is slowing my computer considerably. If I were to delete McAfee and replace it with Spybot, would I have the same type of protections against viruses, etc?

My concern is that I'll leave myself open to serious problems if I don't stick with McAfee. Anyone have information they can share with me?

Thanks in advance,

Dan
