Hi Phil,
Welcome to the forum and I have no doubt your decision to move to Webroot is the right one.
To answer your questions (to my knowledge, and I am no expert, I would recommend logging a support case to get a definitive answer on each)
- I don’t believe so, but the question I would have is why you might want to? For what it's worth, I have found the on-access to be the least intrusive and least performance hungry scanner my team and I have ever used
- Yes, as required. I rarely have a genuine requirement to do so, and when I do it is usually due to third party applications. Usually, the vendor provided said software will likely make recommendations of exclusions if they are needed
- I don’t know on this one I am afraid, if there is, I haven’t used it, recommend logging a support case
When you mention the CPU increase, how much are we talking? As mentioned above, I genuinely have never had an issue with resource hogging from Webroot aside from one machine that was running an OS that was no longer in support.
Sorry I can’t be more help, I am sure others will chime in here as well if they have anything they can add.
Best wishes,
James.
