Spyware symptoms

Here are the most common indicators of a spyware infection:

  • Web browser redirection. Users are inexplicably shunted to a random Web site, or their home pages are reset to advertisements.
  • Pop-up pains. Spyware programs can generate five or more pop-up ads for every page load. This is one of spyware’s big network-performance drags.
  • Wheel-spinning. If users can open a Web browser, but find that accessing a new site is so slow as to be essentially impossible, that’s a dead giveaway.
