Is there a plugin that can scan all scripts for a certain line of text and delete said line?

Hi there, my team have recently run into an issue with one of our devs downloading a malicious plugin that has infected 90% of our scripts with a malicious getfenv() line. We have disabled third-party teleports and sales as a temporary measure, however we will have to get rid of these lines somehow. It is completely infeasible for one of us to delete all of these as there are over 1000 infected scripts, so I'm wondering if there is some kind of plugin where I could input a line such as "getfenv()'\114\101\113\117\105\114\101'" and have it scan all scripts for this line and delete all results?
