SMOBILE Systems and its "antivirus"

Recently, a certain SMOBILE Systems released a "very useful" product, worth $ 4.99. This product is an antivirus for Android OS, which “will protect your device from viruses, spyware and other malicious programs”.

And if you think - why OS, based on linux kernel antivirus? Moreover, now there is not even a hint of any malware for Android OS :)

So it’s still interesting ... What does the program do during the "scan"?
