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.

I'm stumped

As an update. While playing around I get a popup asking for permission to connect to Amazon Browser update from Browser Distribution Services Inc...That appears to be some malware from googling

having explored further it would appear my account is now a 'standard user' and Ralph's would appear to be the admin account.

Use this tool to reset the administrator status and blank the password if required.

Then boot in safe mode and run the free Malware Bytes tool from https://www.malwarebytes.org/dl-confirm/

Wouldn't be surprised AVG is rubbish, has been for a long time now.

Scan with Malwarebytes Anti-Malware, ADWCleaner and put on ESET Anti-virus and scan with that.

Have malwarebytes on my PC but never stuck it on the kids. Will download and install and run. Thats a start.

Tried that and can't run the executable without being asked for admin password. Tried it under safe mode as well and can't run the executable as being asked for password. Any clues from here

Hi. Windows 7 home edition. Tried AVG again and it opens a window for about .4 seconds, fills it with text then shuts it down. Have used the software on pogostick.net and made myself and administrator again and now have access. Am running malwarebytes and will also run adwcleaner as well. I'll report back how we go. Thanks again for your help. I would've been stuck with a reformat otherwise. You've got 3 dancing kids around their pc just now even though they should be in bed!
