When I’m browsing on certain websites, for example [sephora.com](https://sephora.com/), [udemy.com](https://udemy.com/), or [forever21.com](https://forever21.com/), at some point when I click on a product on the website, it opens a new tab that goes to the company’s main page. It only happens on certain websites like these three, not all. I’m not sure if this is a virus because it only opens the company’s page in a new tab, instead of a weird random website? Anyways, I can’t figure out how to stop this, any advice would be much appreciated. If this is a virus what’s a trusted and safe malware remover that I can use?
