i think its a trojan that has been renamed so it is harder to detect an cure. personaly my advise on virus scanners would have to be avg i have used others and i like it best. besides its free and you should give it a try if you dont like it you can always remove it.
but remember not to use both virus scanners at the same time it could work in a negative way. meaning not in ur favor.

i think the simple sulotion to ur problem would be to get the cleaner from this site.
