Safety measures and good practices to protect computers:

  • Install a Firewall: A firewall is a software program or piece of hardware that blocks hackers from entering and using your computer. A firewall blocks communications to and from sources you don’t permit. This is especially important if you have a high-speed Internet connection, like DSL or cable.
  • Use Anti-virus Software: Anti-virus software protects your computer from viruses that can destroy your data, slow down or crash your computer, or allow spammers to send email through your account. Anti-virus protection scans your computer and your incoming email for viruses, and then deletes them.
  • Use Anti-spyware Software: Spyware is software installed without your knowledge or consent that can monitor your online activities and collect personal information while you surf the Web. Some kinds of spyware, called keyloggers, record everything you key in – including your passwords and financial information. Spyware protection is included in some antivirus software programs.
