PCTechHotline definitely is a potentially unwanted program rather than a computer virus. It's a software service saying that can help you fix computer issues by remote support and charges for money per hour. It presents contact information of a remote support company, and when you contact with them, they recommend you to buy fake anti-spyware programs they promote to fix problems have detected in your computer system.
You can see on the title bar of the active program, there is an icon of a remote support person's head. The PCTechHotline window will be opened after you click the head, and this window includes a phone number through which you can receive remote technical help.
