OpenSUpdater

ATP Sandbox Adv. HeuristicsAV

OpenSUpdater is adware and a downloader that displays unwanted advertisements and fetches additional potentially unwanted programs on infected systems. It arrives bundled with free software installers, modifies browser settings to drive ad revenue, and pulls further unwanted software in the background. Although not destructive, its downloader behavior exposes users to more dangerous families that ride the same distribution chains.
