Can you please change your topic, it's a bit inflammatory.

What you're seeing is virus false alarms because the virus detection software on your computer checks for short (e.g. 16 bytes) 'signatures' and not the viruses themselves, and people have put some of these signatures in transactions.  The AV software correctly ignores the blockchain itself but is falsely triggered in some of the leveldb database files. You should configure your AV to ignore the bitcoin directory.

There is no risk to your system here.
