I like this one that features real time protection
I use Malwarebytes (pro version, that runs 24/7) on my laptop alongside MSSE. Someone I know is getting a new computer, and I'd like to recommend MSSE as their anti-virus, and would like them to use a second program for anti-spyware as well (even though MSSE also covers that). Malwarebytes and SuperAntispyware require a paid subscription to do this. Is there a freeware program that does this? Eons ago I used Ad-Aware and Spybot. Do they run 24/7 at all? Are there better free options for what I'm looking for?
