What action did AVG take when it identified the threat?
Did your AVG provide a specific file name associated with the malware threat(s) detection and if so, where is it located (full file path) at on your system?
Each security vendor uses their own naming conventions to identify various types of malware
so it's difficult to determine exactly what has been detected or the nature of the infection without knowing more information about the actually file(s) involved. See Understanding virus names
