Securitywarningserver.online is a website engaged in browser hijacking of Mac OS X browsers, such as Apple Safari, Mozilla Firefox, Google Chrome and Opera. The scam is specifically intended to make users pay money in favor of the crooks who stand behind this fake Mac Support Team alert.
Many users these days are getting regularly bombarded by a lot of annoying criticalsystemserver.site pop-ups. They appear in many browsers and do not let users surf the web. The goal of all such pop-up windows is to scare users into thinking that their PCs are horribly infected with some malware. Then users will be suggested to call some toll-free helplines where they will be suggested to make payment in favor of cyber frauds who stand behind these alerts.
