Recently I have found that when a virus sig update triggers a startup scan, it seems to block or at least severely slow my web traffic down to the point that browsers are unusable. Usually I will find the browser tabs have stopped responding and immediately I can check the tray and confirm that I find NOD32 running a startup scan which in turn seems to have been triggered by a virus signature update.
If I pause protection suddenly my network traffic returns unfettered.
For now I have turned off HTTP protection and that seems to solve it, but of course I am not thrilled to have to do that.
Could it be that NOD32 gets backlogged or hung a file scan for a few moments and when it does the network requests are queuing up because of that?
At the moment the update-triggered scheduler entry for Startup Scan runs at lowest priority - I am wondering if that needs to be bumped up so that the process doesn't get hung up?
Thanks in advance for any input/ideas.
