These are all directed toward Windows O.S.
You can clear your cache using Ubuntu Cleaner or Bleachbit by installing one of them and running it.

Note these are all "PUA" warnings from clam. If you have not disabled PUA notifications then you will often see these reported in firefox cache2 entries. It is not something I worry about. If you do a websearch on this subject, you will see this explaination.

zabadabadoo's pointer is correct - it has been broken for some time, even on Windows I believe.
