title: failed to run '/usr/bin/bash': no such file or directory
body: <p>I've been using gitbash these past few days and it's working just fine. But a while ago, after install a pdf reader with patch file, when I opened my gitbash it gave me the error which says "Failed to run '/usr/bin/bash': No such file or directory".  I don't know what happened and why, but I think the patch file of the application that I installed has something to do with it. My pc antivirus prompted a warning, and I took actions. Then the trouble in the gitbash happened. Please help me, I don't want to reinstall gitbash again coz I also have to install some things.</p>
