Hi davidkaye, welcome to the forum :slight_smile:

Unfortunately, every AV companies are playing catch up, so things will be missed…I have seen sites that spit out new versions of system tool type infections daily, and there are ones that are updated hourly…

The best you could do is submit the files, and if possible, the locations of where they came from.
I would think the rootkits would be most useful to avast, but all of the files would be good to send.
