Where did Fullsecuritysystem.com scam pop-ups come from?
The Fullsecuritysystem.com pop-ups are caused by malicious advertisements on websites you visit, browser notifications or Adware. Browser (push) notifications are originally developed to alert the user of recently published news. Scammers use push notifications to bypass pop up blockers and display lots of unwanted ads. These ads are used to promote questionable internet browser extensions, free gifts scams, adware software bundles, and adult webpages.
Adware is form of malicious software that displays unwanted ads on a personal computer, redirects search requests to scam webpages and collects confidential info for marketing purposes. Adware software can show banner ads, full-screen ads, pop ups, videos, or other varieties of online advertising. Maybe you approve the idea that the advertisements or pop ups is just a small problem.
