AVG Internet Security is a descent product , but its downfall is the large quantity of processes it uses , the lag in boottime , also all the setting have to be tweaked to max to get good blocking results , even then the blocking of zero day threats is not perfect , it misses quite a few samples ( have sent many to their virus labs in the time when I used this product. ) another big annoyance is the stuttering and lag a user will experience when trying to watch a youtube video in hd , even when you have the accelerator function on : this makes no difference! avg is nice for the beginners , but lacks a lot of features ( this I have talked over with other AVG vip fans on skype meetings together with Rachel Bakker AVG'S advacocy manager ) so I hope the devellopment team will implement some of our Ideas in the 2014 products! becuase relying heavilly on signature detection will not cut it these days. Avast has a slight advantage over AVG detection wise , but then again settings will have to be tweaked also , like the detection of pups and the heuristics... Customer support at AVG is not up to par! a while back I had some trouble converting a fresh product key for AVG tuneup 2011 to tuneup 2013. One guy I spoke hung up on me and the other one did not had the slightest Idea on what I talked about : a big faillure in my opinion! our help is much needed on the facebook fanpage , when customers face malware related problems , most of the mods don't have the slightest idea what they are facing , so they are relying heavilly on us.
