I recently upgraded an older computer (733 MHz Pentium III; yes, very old!) from free AVG 7.5 to AVG 8.0. I then noticed some problems with the computer responding extremely slowly. Opening the Process Manager revealed that the problem was the process avgrsx.exe. It was taking up about 85% to 90% of the processor.
It turns out that when the system is booted, AVG 8.0 automatically performs a system scan. On slower computers like the one I’m describing, this process can really swamp the processor; in my case, for the first five or six minutes after bootup. After the scan is complete, the processor overhead for avgrsx.exe drops to zero except when opening an application, etc.
I’ve seem some reports that indicate that disabling the Link Scanner feature resolves this problem. I have not found this to be the case; perhaps people trying this “fix” happened to try it right around the time that the machine completes its initial scan, and thus saw the processor utilization fall about the same time.
