I just use a web based scan such as HOUSECALL. No install and won't upset what is installed.

It's been awhile since I've messed around with more than one AntiVirus apps on one computer. What risks are associated with this?
I seem to be fixing a lot of people's computers lately, and I need to be able to install Avast Home Edition 4.5 on computers that may already have software like Norton, etc.
Thanks!
