Warning - Newgrounds installs virus, trojans and spyware on peoples computers!!! Recently I was on Newgrounds and my anti-virus kicked in to protect me. I thought it was all right then. A few days later I basically had to format and reinstall the operating system in computer because virus and spyware DID get installed on my computer and it got VERY slow.

Boycott Newgrounds. read full review »
