I was infected by a virus. It makes the shift key get repeatedly pressed over and over. This happened to me before and I solved it by scanning with MalwareBytes and AVG. When I went to scan with MalwareBytes it needed updating, so I let it. Unluckily for me MalwareBytes thought it would be kind and restart the computer without my consent. Now, due to the virus, I can't login to my account to do anything, even in safe mode. I have no reset disk or anything that can help me get in. Please help.
