Thanks for the replies.
Unfortunately, I do not use a screensaver, but, like Lars said he does, I use the embedded power saving feature. I have it set for the monitor to turn off after 15 minutes, which basically replaces the need for a screensaver as far as I am concerned. I suppose that this feature could warrant me using a simple screensaver (I’m assuming the ‘Blank’ one supplied with Windows works). Well, nonetheless, thanks for your help.

So, the VRDB process is in my opinion essential to the avast anti-virus program.

Well, I’ll go by that and leave it enabled.

Thanks.
