I have been using Cyberdefender for sometime now.
fast virus updating
i like the 24x7 computer help line - I can talk to someone about my problem - used them to fix a printer issue
very easy to use
haven't gotten a virus crippling my system since I bought it
there free trial is just that, a trial - find problems, but got to buy the software to remove. This is common so it is no big deal.
