What Is Greysummergo.biz?
Greysummergo.biz is a dubious website which tries to make users turn on its notifications on their devices. Greysummergo.biz claims that clicking Allow on its “Show notifications” pop-up will let users see a video, download a file, access a page, etc. If someone does click Allow, Greysummergo.biz notifications will start appearing in a corner of the screen (or on the lockscreen if it’s a mobile phone) and spamming users with ads, clickbait links, scammy messages, fake alerts, etc.
