Pop-up ads, sashay away.

Since they were unleashed on the web, pop-up windows have not only been annoying users, but they have also been a huge nightmare for digital security. Most people know better than to click on suspicious looking pop-ups, but some of them can be sneaky.

But now, we have some essential security advice from an unlikely source: RuPaul.

RuPaul tweeted this key advice on Thursday, giving yet another gift to the world:

NEVER click on a pop-up window that says “update Adobe Flash”



DO go to System Preferences

And let us say: You should listen to RuPaul, because this is good advice.

All around the internet there are fake pop-ups to "update Adobe Flash" which do nothing but attract malware to your machine. The best way to know if your browser and extensions need updates is, like RuPaul said, to go to System Preferences and check if they need updates.

This is not the first time RuPaul has given us this important tip. Back in 2016, RuPaul tweeted the same age old advice:

If prompted to update Adobe Flash by a pop-up window, DO NOT CLICK THROUGH. Go to your system preferences instead. pic.twitter.com/ys7NTcTJfv — RuPaul (@RuPaul) January 28, 2016

The advice was co-signed by an Apple employee:

Even an Adobe employee chimed in:

Hi Ru I work for Adobe and we’re hiring on my team. — j0ry (@j0ry) June 15, 2017

Mashable's own IT Hero, Norman Chen says "Google chrome has flash built-in so you just need to make sure your chrome is up to date."

Thanks, RuPaul!
