On kids gaming desktop -has several accounts and an admin account.For easiness sake let's call one of the users Ralph. He used the PC last night and all was fine. Shut down and ralph went to use it today and found he had to enter a password to access his desktop ( which wasn't correct as he didn't have one set). I switched user to admin and AVG popped up saying licence number wasn't correct ?, accepted the correct licence number but wouldn't startup. So had to shut that down. Not sure if that is related.
Anything I try to do through the admin login pops up a password requester for Ralph to enter a password including re-installing avg in case it was corrupt etc. This includes using windows to change his profile etc.
Anyone seen this before and any tips on what to do ?
I also logged in under safe mode and ran AVG which opened in a shell window. Lots of locked files - not scanned messages which I believe is because AVG in safe mode only has access to current user login accounts and not the other accounts on PC.
