What Is OptimalState?
OptimalState is an advertising application for Mac. It makes changes to promote illegal search engines. This virus targets different browsers, so you will start using a different browser, nothing will change, the device will also be infected. The search engine will be modified with a special infection algorithm so that all requests are sent to the page of the promoted program. These greatly overload the system due to which its active programs will significantly decrease.
Advertising applications are distinguished by the ability to monitor user actions on the Internet and collect data in parallel (passwords, logins, bank accounts). Theft of such information threatens finances and confidentiality.
OptimalState is called adware because it provides pop-ups, banners, coupons, polls, and other intrusive ads to get the user to click on it. Clicks take users to fraudulent sites and overlap the desired information on the computer screen.
It is necessary to get rid of OptimalState to prevent all these problems.

- When installing freeware or shareware, be sensible and don’t rush through the process. Choose Custom or Advanced installation mode, look for checkboxes that ask for your permission to install third-party apps and uncheck them, read End User License Agreement to make sure nothing else is going to get installed. You can make exceptions for the aps you know and trust, of course. If declining from installing unwanted programs is not possible, we advise you to cancel the installation completely.
