I restarted my computer and after opening i got about 50 error messages saying that pretty much every program on my computer could not be found. I then attempted to open McAfee Security center to run a scan and after attempting to open it i got another error saying the program could not be located. I manually located the program but after clicking on it every program on my computer changed to a MCA file type, and now 90% of the programs wont open, even if i manually locate the file location. Its only programs that were changed, any text files, videos, pictures, music, etc. are still the same just my application and programs have been changed to MCA type.
