Win Erx03 virus uses D3oq6395bxosug.cloudfront.net website or adware that is also known as CloudFront – the program responsible for all those redirects and pop-up ads that frustrate your time online. You need to perform a full system scan on your device to make sure that all possible threats get removed from the computer.

Software bundling and deceptive websites might be more dangerous than you think

When browsing online and getting your applications from online sources paying enough attention is the key. When you get redirected to the suspicious website make sure to exit the page right away because you cannot know what malicious content is on that website.
