So my favorite AV expires in less than a month (emsisoft) and i'm trying to think on whether i'm going to renew or not. I love emsisoft what i don't love so much is its probably the only av product i don't ever see good deals for. I see great deals for kaspersky, Trend Micro, bitdefender (family pack can't be beat), eset, & others. On top of that, if i want, i get get norton for free through my ISP. Norton is freakn buggy at hell but has probably some of the best definitions. I also have found bitdefender to be buggy (and a little heavy).
Avast free has great protection & is lightweight but it makes you feel like you're selling your soul. Avast hasn't been know to be privacy friendly and i can tell you from experience no matter how much they tell you the data they sell is anonymous i can be deanonymized pretty easily for someone that gets familiar with the data.
So i'm kind of at a loss what to do here. If emsisoft was the same price as everything else that would be definitely the direction i would. A license for emsisoft for me will be ~$50. Everything else i can get for around ~$20.
Whats very important to me is a top notch behavior blocker (which is one of the reasons i love emsisoft).
