AVG 8. Avira and Avast. Trial.?

I have the new FREE AVG 8 on my computer. The version that has virus and spyware protection. I'm led to believe I'm lucky to have found it, because apparently it's a difficult download to locate. I want to try both Avira and Avast (One at a time of course) to see if I think either is better than AVG8. But I don't want to risk not being able to find the free download again if I uninstall it. So, is there a way I can keep AVG8 on my computer while I test the other two out, and just turn it off or something so it doesn't conflict. I'm not worried about how much memory it uses or if it slows my computer down, because it will only be temporary. I'll uninstall it if I prefer one of the other two. Can this be done?

When you download a program like avg8, it goes to a directory from where you then install it on your pc.

I would not immediately try out avira or avast. Use AVG8free a while and when you don't like it. you can still try out the other 2 programs. Make sure, that you uninstall AVG first, because you can't have two different antivirus programs on you pc. You can have more than one antispyware on your pc. It is even recommendable to have more than one.
