What are the reasons one would want to use an antivirus? Can someone share some insight on how does antivirus actually work?
AVs usually upload suspicious files from user PCs for further analysis to help aid in discovering new variants/types. The odds your AV has seen it is proportional to the odds of you running into it.
The industry is moving away from signatures regardless. Now AVs use runtime heuristics to spot bad behavior of executables and block them even if they've never been seen; Cylance literally only does this and it's pretty effective.
> if being “part of a community” means we need to share our algorithmic, unique conviction engine with Big AV so they can steal our convictions, then yes we will not be able to meet that criteria.
I have no love for Symantec but this new breed of security software can go screw itself for all I'm concerned.
