How to remove “Flash player out of date” virus on Mac?

“Your Flash Player is out of date” is one of the most common scams on the internet. It plays on the fact that most people know that Adobe Flash is vulnerable to malware and that keeping it up to date is essential. By warning you it’s out of date, the scammers hope to trick you into clicking a link.

Everything you need to know about "Flash Player out of date" virus

The pop-up that warns you that Flash Player is out of date isn’t a virus, but it is malware. Adware to be precise. It’s aim is to scare you into clicking a link, which will then download more malware to your Mac. Whatever you do, don’t click the link.

The pop-up can appear on your Mac for a couple of reasons. One is that a website you have visited has either been compromised and scammers have placed an advert on it, or that the site owner has been paid to display the advert and thinks so little of their visitors they are happy to put them at risk in order to earn money. The other is that you have already downloaded malware, perhaps a browser extension that has infiltrated your browser and is displaying intrusive adverts, no matter which sites you visit.

You can tell which is the most likely in your situation by asking yourself if the adverts only appear when you visit specific sites or whether they appear randomly. If it’s the latter, your browser has likely been compromised by a malicious extension. Fortunately, these aren’t too difficult to remove. Read on to find out how.
