I am running avast! free antivirus FTW and im quit happy with it. What are the reasons I should pay for an AV? I dont care about technical support if that's the difference but what else? how good is the avast engine compared to the big sharks like kaspersky, Bitdefender, Trend Micro, and Eset? And for a paid AV, which one would you go for? I had Kaspersky before and it was too heavy on my system even though my system is pretty darn fast. BitDefender caused me a myriad of random errors and crashed even on the v2013, and ESET just gets very bad scores in online tests now they have dropped the ball ever since their reign in the past years when they used to be the lightest / most secure? What would j00 r3comm3end for m3|-| ???
