This is not looking good... some people on this list have gone and installed Google 2FA after realizing their computer might be compromised. Enabling two-factor auth WILL NOT resolve this issue if your computer has been compromised. If you get this warning, you need to bring your computer to someone with real security expertise and have it checked out. Strongly consider cleanly reinstalling your OS, then enable two-factor authentication.
It looks like they're detecting exploit code sitting in people's accounts, mostly in the form of PDF and Office docs and inside RARs. This might explain why snowfl0w is on the list, since he handles a lot of this stuff daily and some of it likely goes through his e-mail (on purpose). It's unclear if this means that your account was successfully compromised. It's more likely that it means someone is attempting to get into your account.
