What is YT5s?

The YT5s virus is a virus you get while visiting the website. That is a free website that allows downloading videos from YouTube. It earns revenue from serving a drastic number of ads, many of which lead to malicious websites or trick you into downloading malware. Usually, it deceives you into installing a browser extension that redirects you to its motherland website, no matter what address you type in a search bar. It can also contain an adware code that will flood your browser with all kinds of advertising.

How Macbook May be Infected with YT5s?

The easiest way to get the YT5s virus is to visit one of the rogue Download from YouTube sites (like, duh) and accidentally click on one of the banners there. Those banners can be distinguished as software notifications or more commonly as download buttons. Then you click the file in your Downloads and begin the installation of the virus.

The other popular way to get your Mac infected is by installing free apps or cracked versions of paid apps with the hidden virus code inside the package. That’s why you should never hesitate to choose Advanced or Manual installation. You’ll see all the additional hidden packages and will be able to prevent unwanted software from being installed on your computer.

How to Remove Ads from Windows

The algorithm required to remove ads from Windows is the same as for macOS – you should delete all unknown extensions from your browsers and restart your computer. Then install AdLock for Windows and keep it enabled. The price starts from $1 a month, and for that cost, AdLock will block ads in browsers, applications, and games, stop tracking and prevent malicious sites from infecting your device.  


Is a virus?

No, is not a virus. It’s a website that allows you to download videos from YouTube. However, it has a lot of intrusive ads and banners disguised as download buttons that can contain a redirect virus. That said virus will redirect you to the main page no matter what website you type in. It can also increase the number of ads popping up. 

Is yt5s safe?

It’s as safe as a service that crosses copyright laws can be. The website is relatively safe if you have an enabled ad-blocking extension like AdLock, for example, as most threats come from the ads. However, if you download a file from the website, there is a 3/10 chance you’ll get a trojan or adware. Also, the first thing you see when opening a website is an offer to install the YT5s application, which is a huge red flag.  

What to do if yt5s is not working?

There are plenty of other services you can use to download videos from YouTube. I can’t list them here for ethical reasons, but I can give you a hint about the safest option. You need an open-source service which is basically a command line. Most likely, all other YouTube downloaders run it on their background, so why use a middleman when you can go straight to the source?  

Can I really download YouTube videos from YT5s?

Yes, you can, but be very attentive. Since May 2022, YT5s has been serving malware disguised as a video file ready to download. So, if you see a filename extension .iso, don’t download it. 

I have clicked on notification ads, is my computer infected?

No, notification ads are not that dangerous and can’t infect your computer. They can lead you to a scammy web page or initiate the downloading of malware. To avoid infecting, close the page, stop downloading, and delete the questionable file. 

Why am I seeing ads delivered by yt5s in the lower right corner of my PC?

You see YT5s ads in the lower right corner because you gave the website permission to send you notifications. In most web browsers, you can disable notifications from a website by clicking a lock icon next to the website address and choosing Permissions. Find Notifications in Permissions and select Block. To block notifications in Safari, click Safari in the top left corner of the screen and select Settings. Click the Websites tab, click Notifications and block notifications from
