I have a problem of late with AVG8 (free) running my CPU at 100% and locking my system up. Starts auto scan.
Posted this on the AVG anti-virus forum.
[Question]
My Auto Scan Scheduler runs AVG8 in the background and of late has been at 100% CPU set to mid position.
All of a sudden everything freezes on my PC, internet, everything, and I know where to look - turn off AVG.
I cannot do a scan anymore. Have let it run when not at the PC, but after 2 or more hours it's still going.
Have used 86 GB of a 200 GB HD.
It is a very sloooow scanning product and hogs 100% so no work can be done. Even setting the slider to low it still take 55-75%.

Check for a corrupted or incomplete installation...
Disable Windows Defender... disable the Vista UAC and restart...
1. Download the latest AVG Free installation package from [free.grisoft.com]
2. Run the AVG Free install file
3. Choose the Uninstall option and follow the setup wizard, when you get to the part to remove user settings, select it.
4. Restart your computer then...
5. Now reinstall AVG using the setup file you got in step 1 and update it.
Restart the system twice before you re-enable anything disabled earlier.
This seems like an awful lot of trouble to go through just to 'hopefully' fix this problem. I have been a faithfull AVG user through many versions with no real problems. This time I may see what else is available to try. I have to uninstall it anyway according to them.
