I have a security question!!!?

I'm wondering if it is smart to have win.defender/ spybot %26 avast installed in my laptop. I don't run them at the same time,although avast is always running ,but is it smart to have'em all installed in my computer. obviously I don't want to pay for antivirus software. my laptop came with norton (trial) but I didn't renew I didn't like it. Am I doing the right thing.PLZ HELP!! THX

you should only run one antivirus software so they dont conflict.

yes
I did the same thing, plus the free version of AVG. It does a pretty ok job although it does tend to make everything run slower. I re-purchased Norton and installed it yesterday--you think you don't like something until you don't have it and the free stuff misses something! I would try another route-- Trend Microcillian is good, also.
Keep the Windows firewall turned on. Don't use Internet Explorer, use FireFox instead. Don't surf porn sites or pirate software, and you should remain virus free.
continue with norton and due the renue of the norton.
you should try NOD32 antivirus system, it is antivirus and firewall at the same time
I dont think it will hurt anything. I wouldnt suggest letting them all run at once though.
