Somehow, my wife's computer picked up a virus (and other things???) over the weekend. She thinks she clicked on one of those pop ups that claim it can clean the system. Regardless. . . I cleaned it with Trend Micro and with Malwarebytes. But now, whenever the machine reboots an explorer-type window opens showing one file -- helper.sig -- in c:\program files\common I ran through the eight steps and attached are the (another run) of malwarebytes, superantispyware, and hijack this logs. Any help would be appreciated. Thanks.
