I got an old laptop from work that I run Ubuntu on, I love it. It is what i use all the time when not working.
The family pc, I use AVG antivirus. I also run malwarebytes as well as Ad-Aware, spybot search and destroy and Glary utilities.
AVG and spybot run all the time. i run Ad-aware, malwarebytes and Glary on a periodic basis.
Malwarebytes is one i just started running. A tech guy at my ISP recommended it. It is pretty fast where Ad-Aware and SpyBot can take an hr each to run a full scan.
I ran Malwarebytes recently and then ran Ad-aware and SpyBot after and they didn't find anything so Malwarebytes is pretty good. Glary utilities cleans up registry problems.
i'll have to say that my computer doesn't seem to be as fast as I would expect. i think it might be from having all these utilities running on it.
It is an Hp with 2.5 GHZ with 512MB ram. I might try upgrading the ram to see if that helps. It doesn't seem to run any faster after I run the cleanup routines either.
