Built in Viruses

Has any Acer Aspire computer owners out there recently bought a Desktop that comes built in full of Viruses in the built in Game’s? I bought this AA M1100 around the end of last year at Wally World(Wal-mart), and after unfortunately after owning it a while, and re-installing the OS with the built in Recovery, that all the games that come with it are loaded with virus’s. Now, every time I have to re-install the OS, I have to uninstall all the game’s, or anything Acer game related. Is this normal(SNAFU) or Freak computer that I bought?
