I've noticed the same, but others have no issues like this.
That avgsrx.exe is AVG's Resident Shield. The general feeling is that it isn't wise to disable it.
There's more on this here;
I have been on a yearslong quest to speed my bootup time. A few months ago I got it down to two minutes but lately is has crept back up to more than 3 1/2 minutes.
When I boot, I watch the processes in Task Manager. AVGSRX uses the cpu for almost two minutes. This seems to be longer than it used to.
Does AVG accumulate "garbage" as it ages?
Would I benefit from uninstallng it and reinstalling?
Alternatively, can I restrict what AVG looks at during bootup? (I would still occasionally do a full-computer scan).
