Running Safari web browser. I keep getting a warning with a tab open that says:
Your system is infected with 3 viruses!
Your Mac is infected with 3 viruses. Our security check found traces of 2 malware and 1 phishing/spyware. System damage: 28.1% – Immediate removal required!
The immediate removal of the viruses is required to prevent further system damage, loss of Apps, Photos or other files.
Traces of 1 phishing/spyware were found on your Mac with OSX.
Personal and banking information are at risk.
To avoid more damage click on ‘Scan Now’ immediately. Our deep scan will provide help immediately!
1 minute and 16 seconds remaining before damage is permanent.
Web address that displays this is:
The “Your system is infected with 3 viruses” warning is a fake (misleading ads), you can safely ignore it. But, you should be alerted by another. If you write that this warning is constantly appearing in your browser, then I think that your browser has become a victim of adware.
In order to remove adware (in this way, you will remove “Your system is infected with 3 viruses” warnings), I recommend that you do the following:
1. uninstall suspicious applications
2. reset browser settings
3. scan your MAC with Malwarebytes or another malware remover.
This is described in detail in this manual: How to remove adware from Mac
