I have AVG, but it doesn't consider TPT, Google Chrome and crap as viruses. (I have default settings, AVG must love me <3)

This is exactly what anti-virus is supposed to warn about, nothing wrong there. Anything you download from the internet 'could' be a threat. If it updated from tpt itself, or got it from the main download page, just hit allow, it is doing its job. I use Avast! and it does this as well every update.
I use avast and it has never warned me about TPT. I do have my Heuristic sensitivity on Normal rather than the higher setting though.
