I went through a major infection today. MalwareBytes attempted removal but failed. I downloaded Avast and ran a bootup scan, which removed most of it, but a nasty SYSWOW64/dnsapi.dll virus remains. My connection to the internet is terrible, and some websites fail to load at all. MalwareBytes and another program refuse to install, and Avast bootup scan finds the virus, but fails to remove it.
I am using Windows 7 64 bit
