Spyware

Spyware, also known as "adware," is software that sends information from your computer to a third party without your consent.

Besides secretly monitoring a user's behavior, spyware collects personal information, which could lead to identity theft. Retail companies use spyware to gather data about customers' Internet habits.  Spyware may also redirect the web browser to malicious sites, allowing a third party control over the user's computer and the installation of additional harmful software such as viruses and Trojan horses.

Machines infected with spyware may experience:

  • Slow system performance
  • System crashes
  • Difficulty in uploading the web browser
  • Frequent display of pop-up ads and error messages
  • Diversion of the search engine and surfing activities
  • New icons appearing suddenly on the computer
  • Certain browser function keys that have stopped working

In case you experience any of the above symptoms on your computer, or suspect that your computer is infected with a spyware and/or other malicious program, please take the following steps:

  1. Disconnect your computer from the network
  2. Disable the wireless connectivity
  3. Contact your departmental administrator, DSP consultant, or Computing Services Help Center at x8-HELP(4357) or advisor@andrew.cmu.edu
