Hi,
I'm having same problem on my network of Rvhost.exe. It is infecting my system. I have already installed the Avasta 4 Home edition but unable to remove it from my USB drive. When ever I reconnect my USB to system it has a folder naming "newfolder".How can I remove or secure my Network from this Virus/Trojon??
