Ultimate Guard

Ultimate Guard pretends to be a unique anti-virus and security program that can detect and remove threats to your PC's well being, but in reality, Ultimate Guard is just another rogue threat from the System Tool family. Ultimate Guard will create fake system scan results and inaccurate security alerts about infections that aren't on your PC, and may also block a variety of programs or hijack your web browser. You can remove Ultimate Guard and all attendant Ultimate Guard problems by scanning your system with updated security software in Safe Mode.

Ultimate Guard: A New Face for an Old Rogue Threat

Ultimate Guard's website uses fake social media content like Twitter's 'tweet' messages to make it look like Ultimate Guard is a popular and reputable program, but Ultimate Guard is really just a new variant of the well-known System Tool rogue threat. Other examples of rogue programs in this family include System Tool 2011, System Tool 2.20, and Security Tool. Ultimate Guard is one of the most recent members of the System Tool family and may not be detected by security software that lacks recent threat database updates.

Ultimate Guard will create a wide range of fake errors on your computer to make you believe that an army of infections has somehow slipped past your other security programs. Some examples of potential fake errors by Ultimate Guard include:
