Having self knowledge about safe computing habit/safe web surfing/downloading is good,it will boost ur protection against getting infected as well as it will boost any AV protection capability. But as a AV, i'll only say that AVG is not a good product like it older 2012 version. as per as detection/removal capabilities it still lacks plus issues of having false positive. If u r looking for AV then search for other AV who is lightweight plus having good capability for removing malware & having a decent detection rate/virus signature database with less false positive issue. there are some freewares out there in market, no need to pay any penny.
