Eh. As long as you aren't going to virasspammerbot.porm I think you'd be okay.
That has absolutely nothing to do with it. ALL public IPs are constantly brute-forced on popular application ports like FTP, SSH, Telnet, WINS, HTTP, SMB (Windows file share), RDP, VNC, SNMP, etc as well as easily automated Windows attacks. Without a proper firewall in place, it is a very bad idea. Usually you'll get 5 or 6 bots a day hitting up your ports and they don't stop for hours on end.
