There’s something else going on here that you’re likely not being told. I have never seen Avast remove the programs you listed. I would be willing to bet the computer has something wrong and someone trying to help, tried a couple things they thought would fix the computer and now your friend is missing programs.
Do you have access to the computer? Can you see the programs mentioned are gone, in the add/remove programs and from the start menu? Is the problem that the desktop shortcuts are missing? Desktop shortcuts can easily be recreated. Can you give us more information please.
Thanks,
Laslo
