oh -- sorry . its only a spyware and SOME ( stress some since it doesnt find all malware) malware finder/cleaner program. However, if you are not a system admin at work or a basic computer user, I wouldnt use it. it must be used with care as it can be destructive if you dont know what you are doing and removing. If the software finds something, it tends to remove stuff from recycle bin,tempfolder and internet temp folders. I use it because if I know a pc is infected or suspect it is, no matter how little or how bad, its faster then anything I know of to clean the pc and get it back asap. it does the job the first time around unlike others.
With you asking me what is it makes me hesitate to endorse this program for you, like i said can be harmful in wrong hands and make OS rendered unusable. You would just have to do a complete re-install if that happens to save time.
