I finally decided to return to Avast (And retain my account), because your claims about AVG have been proven
TRUE.

AVG discovered to have several disadventages including:
1. AVG can't be updated in "Safe mode with network support".
2. Opening AVG, don't opens the anti-virus interface itself in safe-mode (Like in the case of Avast), but rather a very compliacted and problematic "Commend line scanner".
3. AVG seems to consume much more memory than Avast.
4. AVG seems to consume 100% of the CPU during scanning, while Avast don't.
5. AVG considerably slows down the computer during scanning, even if the scanning priority isn't at the max (Avast slows down only at max scanning priority).
6. There are indeed have an indication to cause more false positives than Avast.
