About this infection
SDos is a highly questionable Google Chrome extension that is causing your browser to display all kinds of advertisements on your screen. If you have this extension, that means you were recently redirected to a website where a pop-up asked you to install this threat. Whatever you clicked on, it installed.
And now adverts are interrupting your browsing. It’s not really a high-level infection, and although it will perform unwanted actions, it will not directly harm your computer. However, it could lead to a much more serious infection, which is why you need to delete SDos Chrome Extension right away. The ads that it will generate will not always be safe, and if you engaged with something malicious, you could end up in serious trouble.
What does the extension do?
You might be wondering if there was a way to prevent these infections, and it’s not really difficult to do. When a pop-up is offering you an extension this way, you shouldn’t press on anything, not even ‘Cancel’. Even that could cause the extension to download. What you need to do instead is close your browser or the tab. The pop-up might not allow you to do that, and if that is the case, then access Task Manager, look for all Chrome processes, and end them. If the reason you got redirected to the pop-up is adware, you will need to deal with that too because otherwise you will end up having to remove SDos Chrome Extension and similar, again and again.
When the extension is installed, it will add itself to Google Chrome, and start filling your screen with adverts. Even though other browsers are safe, don’t just switch to them, thinking the problem will go away on its own. It’s not. You’re gonna have to uninstall SDos Chrome Extension. And best do it as soon as possible. Until you do, do not engage with any of the ads or pop-ups. These kinds of infections do not differentiate between safe and malicious sites, so you could easily end up with a much more serious infection if you are not careful. The extension will bring nothing but trouble, and it does not provide any useful services. It will also slow down your computer, and make your browser crash more often. You need to delete SDos Chrome Extension as soon as possible because otherwise, you could be putting your computer in danger.
