Interesting, they do suggest and don't say you must. And they say it can and not it always will. IA little too muck OC and a task fails I have a hard time believing it can fail from AV and not throw an error.
But either way I do not run any antivirus in Linux and Linux is all I fold with. Plus I hardly ever fold anymore anyway.
From what I understand any work unit I turn in today will not even be looked at for another 20 to 25 years they are so far ahead not expecting all the hardware thrown at it.
It is student run program at a college and computers go offline on a weekend and stay off until the students come in on Monday. In the Summer, fugitaboutit.
BOINC I use Linux and windows, and with windows just what ever MS gives us for free. Not sure if there even is any settings.
I say don't worry about it in BOINC as do as you see fit in folding. Kapish?
