After running a scan and identifying and removing a few threats related to the QSearch/ChillTab search engine virus (which I have been dealing with and trying to rid my machine of for a while now), I was prompted to restart my machine. Once I logged back in and tried to open Malwarebytes again, I got a message saying "The Application is Damaged - please download and install a new copy of the software to replace the damaged files" (see first screenshot here: https://imgur.com/a/DzEqVMU).
So I downloaded the software again and tried to install and got a message saying "The Installation Failed" (see second screenshot here: https://imgur.com/a/DzEqVMU).
After that I tried restarting my machine, same "Installation failed" message. I deleted all previous Malwarebytes files and restarted my machine, same message. I went through my application list and removed anything I hadn't used recently just in case there was some malware in those files. Still got the same message.
I'm not sure what the next step to take is here -- I am concerned that there is some malware on my computer but I cant get Malwarebytes installed. Any help would be appreciated.
