Yesterday the website was inaccessible, looked all jumbled together like I tried to load it on an old flip phone. Today every time I'm browsing a file page like a vehicle model the website is hijacked spam or an add page asking to allow notifications or even shows up as a captcha challenge saying "click allow if you are a human" thus allowing them to send notifications. Windows 10, Chrome. When I click "X" on the add it sends me back to google. These ads do not appear anywhere else on the site but "downloads" pages. The add or spam hijacks the page automatically similar to opening a new tab. it does not come up as a new tab. It takes the place of whatever page I was on.
