Безопасен ли cdn77.org?

This site is known to distribute adware, but isn't caught by web filters/antiviruses. This adware will attempt to scam you out of your money by causing your web browser to open this by default, and once you're on the site, it will resort to sending you a message claiming that in order to remove it, you will have to call a hotline (which will potentially phish you out of your money). It also primarily uses the strategy of pretending to be a system error, much like a rogue program. I arrived at this site after being linked to an unused domain, so steer clear from those, or try to at least be aware of a domain's status. It hosts several subdomains with different IPs/names, which are also potentially harmful.
