Very good Internet Security

I had Norton for years on my PC and was subjectively satisfied ... until I came across several reviews. NORTON has waned in terms of PC security (virus detection). A friend recommended me G DATA. He was right. G DATA took place after the very simple installation 12 !! Viruses and 1 !!!!! Trojan on my PC.
G DATA has on my computer a very low consumption of resources, has since yet no false alarms and the associated file shredder also works very fast.
I will stay definitely in G DATA and have recommended this IS successfully.
