Norton IS 2012 - idle scan locks computer

Hello,

 

I installed Norton Internet Security and Norton Utilities 15 a few weeks ago.

 

Norton's Idle Scan (or whatever it does while my computer is idle) is locking up my computer. If I have no programs open, just the desktop, it appears to be okay. If a program is running, forget it. I can move the cursor until I click something. Then the working / not responding circle shows up. The only thing I can do at that point is a hard reboot. If by some miracle, I can get to the shut down button in the start menu and it responds, the computer locks up when the screen says logging off.

 

To say the least, this is causing problems.

 

I have Vista Home Premium, service pack 2. My prior anti-virus was Avast and Malwarebytes.

 

Thank you for the help.

 

Sincerely,

Shalie
