I decided not delete the prior directories
i elliminate two entries about malwabytes, but I forgot to capure the key....

This virus take possession of several folders, and seems put to zero the groups of users of some files. And those files was not possible to open. After about 48 hours i haven't observed the virus. But may be some strange behaviours stay in some place......
