It looks like they are at least a legit company, but IMHO I wouldn't trust any online scanners.

You can grab a scanner from Microsoft or Malwarebytes that will give you reasonable results, but other than that I'd only trust a quality, up-to-date A/V program resident on your machine.

Just my $.02.
