Scared of using the internet

[Slanderous]

Just... don't use things like McAfee or Norton. Though they work fairly well (despite their previous reputations), they still slow your computer down tremendously in my experience. Though if I were to recommend something, I am not all that sure. I haven't personally tried all that many different ones.

I know Avast works well, even the free version, though it was kinda "ad"-y for a while (not so much anymore it seems).
Trend Micro seems old, but functions well, but this is a business solution.
Hitman Pro I've seen and heard very good things about, dunno about its price and availability.
MSE is simple but definitely good enough for casual use.
360TotalSecurity I've heard has good results, but perhaps a sketchy privacy background considering they are Chinese.
Malwarebytes is definitely a good shot, but free version is only on-demand, not active protection. But keep it around anyway!

Dude, I'm not even sure if you can call Norton an actual anti-virus. It's basically a pile of steaming shit. Same goes for McAfee.
