Norton Or McAfee

I recommend ESET Smart Security / Antivirus for sythe users / runescapers.
It's amazing at detecting spyware, trojans, java driveby's and whatnot.

I use smart security myself, it's very good. It's very leight on the CPU and detects everything.

Other ones are more basic / virus focused and usually can't remove some trojans, keyloggers, let alone java driveby's, rootkits
etc.

 

My personal favourite is Avira Antivirus PRO, it has a tonne of features and if used with malwarebytes its a good combination to keep the viruses out.

Oh and it has my favourite feature of blocking java-drive by's or other dodgy websites. which helps if you dont wanna get hacked and lose everything you earned on runescape.
