Here is the page, may need translated- -http://www.comss.ru/page.php?id=202- (not sure which Eset forum this needs to go, so just stuck it here) It does not appear to have a digital signature. When ran it puts up no suspicious activity, as per Prevx. I ran it through a couple online multi-scanners and it came back clean. Just no digital sig is a little weird. This does not install, just runs on demand and looks to be updated daily with sigs included in download.
