This fixes most of the Antivirus rules. I still need to test Sophos from event log samples I have. I do not have access to F-Secure Ultralight SDK Event.System.Provider logs so can't validate the F-Secure Antivirus one. Had samples of the legacy versions hence fixing the f-secure_legacy.yml one. windows_defender did not require any fixes and can remain as it is

Don't worry about the FS ones, we only added those cause they were our employer at the time. Is this PR ready to merge and does the other one still apply too?

Hold off on this one until I check Sophos. I have a bunch of samples from prior cases just have to dig them up first.

@alexkornitzer This is done and the fix has been validated on Sophos. With the #text fix it is an exact match to the older version
