I will only talk from personal experience, I use kaspersky currently, I have used AVG, Avira, Avast and also Bitdefender, and I have found bitdefender to find more threats. Yet at same time as long as you keep for at least 2 months those threats in quarantine you will find that bitdefender will alert to many of those extra catches were false postives after updates. At work although this was sometime back when they used Trend Micro, which was so useless to the point I wanted to take an advert out because most companies my side of the world were using it and boy what a piece junk. I managed to talk my boss into allowing me to run AVG on my work pc to prove Trend Micro is not a trend setter and I was right AVG got all PCs working at full speed again because at that time I was using AVG on my own Pc at home. I used AVG because it allows for manual updates so if i had a pc with no internet connection I could still use AVG to clean it up. Avast is also extremely reliable and again far better in my experience than Trend Micro. Granted I used Trend Micro sometime back and may be now they are top of the ladder but they got paid a nice sum from these companies and I had use AVG at the end of the day so yeah I could not care less about antivirus statistics of today i remember my experience in reality rather than some graph posted around.
Also at times I found Avira to ahead of the game many times, not always but often enough to be noticed by me when I used it but I will happily use avast or avg if they were slightly cheaper at the time of renewal of license because I used them before and I trust. Trend Micro will never see a dime from me because they were rip offs.
