When I first got my computer, I downloaded a FREE AntiVirus program from Road Runner. I think it was McAffee. Well, I contracted a virus within the first month and had to have my entire computer emptied out and "disinfected".
Afterwards, I spent the money for Norton, and haven't had any trouble since. When I'm using Norton, I know it's watching out for me. It lets me know when there's been a threat to my computer, or when I'm about to go on a site that isn't safe. I get updates automatically, and notices when my service is about to expire. That way, I'm never without protection.
Yes, definately...
