Website redirects are most commonly caused by adware and other types of malware present on your computer. The aim of these unwanted programs is to point you towards certain types of advertising or dangerous code that could further damage your system.
What causes a website to redirect?
Web pages may be redirected to a new domain for three reasons: a site might desire, or need, to change its domain name; an author might move their individual pages to a new domain; two web sites might merge.
Why do I get redirected to random websites on Chrome?
A Google Chrome redirect loop error occurs when the owner of a website changes their website URL (address) and the old one redirects you to the new one. Because this could be used maliciously, Google gives you an error when you try to reach the site.
