Hmm, that is very strange. I personally do quite some burning with Nero and avast loaded all the time and never every had any problems. WinXP, too.

The problem here is that respective testing is quite costy - you lose a medium with each try… :slight_smile: Anyway, I’d like to know if the problem stops happening if you turn off the on-access scanner, or just the Standard Shield etc… I.e. to get an idea which part of avast is responsible for the problem.

Thanks
