Part of the AVG anti-virus system

It is apart of the AVG, the only time it is used is when AVG is doing a computer Scan. Its not dangerous at all

uses lots of memory
is process for AVG Internet Security
slows down machine; sometimes locks up
Hmmm...part of AVG, which I am supposed to have disabled, but which is running on my machine...! Possibly via Firefox or Excel (when I went to remove it, it said that Excel had to be closed before continuing...?!). So now it is all going away. So my rating is that it is annoying and exhibiting behaviour which may be dangerous.
After installation of AVGFREE 2013 it started to hog almost 200 Megabytes of memory. It is supposed to be active only while scanning, but at my PC it runs 24/7.
