California-based TrustedID announced its acquisition of Unsubscribe.com, the creator of Social Monitor, an antivirus for social networks.

“Unsubscribe.com’s Social Monitor, the most advanced security tool for consumers using social networks, scans apps within Facebook, LinkedIn and Twitter accounts to determine their risk. Social Monitor has evaluated over 100,000 apps to date, covering more than 90% of all Facebook app installs.”

The tool allows users to assess the risk level of individual apps and, if necessary, remove them from their social-network account.
