Rana, did you try what I suggested? ... 0.0 - I think it has a good chance of working....
IIRC AVG moans if it has a problem - so it's probly not that - though course it's worth trying. But to me it seems really dumb to ask you to disable antivir progs - the best way to stop getting infected is to find the viri *before* they spread all over the place (though of course larian is 99.99999% sure to not leave a virus on the disc - but where do you draw the line?)
