What is SystemTools?

The Malwarebytes research team has determined that SystemTools is an adfraud tool. These adfraud applications earn money by connecting affected machines to websites in a way that makes the advertiser think you viewed their ads, when in reality you didn't.
Even though you may feel there is no harm in it for you, these trojans may compromise your security and use your resources.
