Goa, for a few months I've been using Online Armor to which I switched from Zone Alarm Free. It works like a charm so if you want to you can try it too.
Comodo should be fine as well though.

Hi, cause  this issues , I have some questions
http://www.mindwarppavilion.org/smf/low-techs-at-the-wheel/should-my-dvd-drive-go-to-the-garbage-t5382.0.html;msg83941#msg83941

I' ve been using at work PC the three softwares above (avast, Comodo, Ad-Aware 2008 free).

Now at home PC finally kicked out damn Panda.

1) avast: is there any setting to make it a scan on demand, but instead asking you what to do each time find viruses or whatever malicious, ask you at the end what to do. I mean, is a lil anoying seeing you left the PC making a scan on demand, and to find is stoped just at 20% of files checked, asking you what to do.

Later, about Comodo annoying issues...

so it learns....I will try...thx bb.
