"How exactly does the lockup manifest?
I mean, can you still move your mouse cursor? Can you maybe select the icons on the desktop, but when you click them, nothing happens?"
I can usually click on one icon, then nothing happens and I can not click on any other icons, but the mouse still moves. I can not shut down by selecting start and shutdown, nor can I click CONT,ALT,DEL. I have to hold the power button and force a shutdown.
"What is your operating system?"
I don't know what difference this makes as I have changed nothing since I loaded the program initially, but it is Windows XP Pro with SP3.
"Which is your firewall?
Did you have any other antivirus before avast in this computer?"
I do not have any firewalls except for the antivirus that I know of. I do have another antivirus installed that has always been there as well (Trend Micro). I have changed nothing in the Trend Micro settings either.
As I stated, this has happened in just the last 3 or 4 weeks and I have changed nothing.
