You bet it will slow down. Just compare Norton Anti Virus solution versions 2003, 2004, 2005 & 2006. It's like slow, slower, slowest, crawling... (well you get the idea).
I run Windows XP at home and no protection software is installed (resident / layers). Occasionaly I run free AV, MS antyspyware, SpyBot S&D but basically it turns out they don't find a thing.
How do I do it: using linux router and more importantly think before you click!
That's right - use your brains & you don't need any security suite.
