I'm noticing unexplained slowdowns and crashes, particularly when searching the Web or  operating a security or anti-virus program

  My Web browser opens to a strange homepage, returns unexpected search results, or directs me to unsolicited websites

  I find that my mouse, keyboard, monitor, or CD/DVD drive is unresponsive or performing erratically

  Pop-up or pop-under browser windows are opening when I am not surfing the Web, or are opening so often as to be distracting

  My security or anti-virus programs are not working, and/or I cannot visit security-related websites  

  A program or application that I have attempted to uninstall reappears when I restart my computer

  My PC seems to “have a mind of its own” and is difficult to control

  All of the above!!!
