On demand scan slowing PC out of the blue

We have had an on demand scan running for months now on many PCs. It just does processes, registry and memory with 20% set as CPU usage. No reports of any problems. Takes about 6 minutes. Until last week, I have now had 3 reports of the scan slowing the computer significantly. Taking out the processes option does not help. I see nothing untoward in the logs and nothing has changed as far as I am aware. I am testing agent patch 2 to see if that helps, but has anyone else come across this recently ?

Re: On demand scan slowing PC out of the blue

See below. We were also including 'running processes', but I took that out to see if it worked (although I see it still says it scanned 4...). It did not help. I am getting reports back that it is better with the new Patch 2 applied. Not sure this will help much....
