Your system is infected with 3 viruses! Scam – How Did I Get It

The main method by which this online scam is spread across Macs is believed to be via multiple different compromised web pages.

Another method by which victims could have started seeing such redirects is by having a PUP (Potentially Unwanted Program) that is installed on their Mac. These programs often hijack the installers of other free apps which is also known as bundling. This makes them a bit difficult to detect while you are installing a free app on your Mac, because of the fact that they are located in the “Custom” or “Advanced” installation options posing as “free extra” or “optional offer” to the current installation.
