Much improved from V3, only have 11% of files that require scanning whereas V3 I had at least 25%. Seems that "trusted file" data has been increased greatly, which is good as some files in V3 were clearly ok to trust but were flagged as not. This seems to have improved.
currently have 88% trusted and 12% require scanning. I do have some files that will worry any of the a/v systems, being various system recovery/repair all-in-one cd isos and the necessary files to build them.
There are a couple of false positives amongst them and have had to tell N 360 to ignore them.
