Identity thieves use all different types of tactics to gain access to your personal and financial information — including posing as tech support companies. They often do this by using popup messages alerting people browsing online that their computers have viruses but can be “fixed” by contacting a (fake) security company.

If you ever see a popup message about a free security computer scan, ignore it. Do not call the number listed for the scammer security company. If you’re concerned about your computer security, find out what current security program you’re using on your computer and call that company.
