I have a problem in my computer ?

First just run a full system scan with (Mal-ware Bytes) since key-gens are sources for Trojans & malware (Thats if you have access to another pc with internet. Make sure that the virus is out and then you can double check your internet connection. Second try out your internet explorer and take note of any notifications because they are critical to diagnose your system. If IE is not working i do recommend another browser.
