AVG dont have good cleaning template. Im using AVG and it detected-deleted once a worm on my system. Yet, I was still doubting, wondering if my system is completely clean. So I checked the trendmirco online scanner http://housecall.trendmicro.com/ and it detected an infected batch file in my system left by the worm. So if I were you i would check it again using trendmicro online scanner. Its for free and would take only a couple of minutes. Take the benefit of the doubt. Trend Micro online scanner is the only online scanner that received a certificate of 100% virus detection and a certificate of 100% effective cleaning template.
