Running ESS 4.0.437.0 on XP/SP3. In Scheduler, there are two start up scanners checked. Both titled Automatic Startup File Check. One launches at boot up, the other I believe after an virus update. The one that launches at boot up, I'm sure is the one that causes the ESS icon in the taskbar to spin. It seems to cause a delay in my browser, Firefox, open directly after startup or reboots. I'm thinking of disabling this one, maybe both. Is it safe to do so?
