Trojan.Multi.Brosubsc.gen Detection & Removal

Trojan.Multi.Brosubsc.gen is the designator of a detection used by one specific anti-malware application. It has been reported by multiple users and has caused some concern.

The good news is that the detection is likely linked to a component that, while undesirable, is not as harmful as you might fear. The "brosubsc" designator is shorthand for "browser subscription". This is typical for browser hijackers that work by convincing users to somehow click "allow" on the page and accept push notifications from a misleading website.

Once this permission is given and the user is subscribed to push notifications, the misleading or untrustworthy page can send ads and pop-ups to the browser. This behavior is usually undesirable, as misleading sites often work with rogue ad networks and may source through them ads that link to unsafe online locations.

However, the Trojan handle at the start of the detection name is probably scarier than it looks, given that the problematic component is very likely a browser hijacker.

Browser hijackers have different levels of persistence. Ones that work through notification subscription are usually easier to remove.
