I just use AVG (premium) and what Dylan said, common sense. Haven't had any problems at all.  

I use AVG & PC Tools Internet Security. AVG is okay, but PC Tools was a little harsh on my pc D;. Like everyone said in the above posts, Norton sucks. It basically killed & lagged my pc when I had it xD.  

Kaspersky PURE  

Malware Bytes is very good. Doesn't blow up in your face all the time.  

Thanks for all the advice/suggestions guys. I really appreciate it. If it's true that Norton does slow down your computer, then I'll try removing it and see if it helps my computer.  

AVG. It's free.

I used to recommend AVG but it has gotten worse over the years, and Avast! took its place. The above recommendations for Windows is also good, and I also install that(especially on slower computers) because it's much less bulky.  

Try the Kaspersky trial. It's amazing. I found a key logger.  

I use Avast antivirus, no lag made, if I go to a harmful webpage, it aborts me from it with my permission, warns me of anything, tells of suspicious sites when I view them, does the job fairly well.  

I personally use a combo of Kaspersky and MalwareBytes.

Never ever use Norton

lmao, my brother works at Staples in the tech department and he has to recommend Norton when someone buys a new PC. It kills him inside lol

I'd recommend microsoft security essentials. It's pretty good at picking up stuff immediately.

Same here.  

Avast!, MalwareBytes, and the aforementioned MSSE are all solid anti-virus programs.  

Avast! is brilliant. I'm still using the free version and I've had no issues so far.  

I used to have norton, now I wing it and have none
