What caused this problem?

Many common types of viruses hijack certain file extensions on your computer, including file extension OMA, file extension exe, file extension lnk, file extension bat, file extension com, file extension pif, file extension scr, and file extension cmd.

While the virus is still on your computer, any time you run a program, it silently runs the virus in the background as a means to make it difficult to remove. When your antivirus software cleans the virus, however, the affected file extensions are still hijacked, but because the virus no longer exists, Windows doesn't know what to do, and you get the error window as seen above.

How does the fix work?

When you install PC MightyMax File Extension Repair, it will scan your computer for file extensions that have been hijacked or tampered with in any way. When you click 'Repair Now', any affected file extensions are restored to their original state, allowing you to open programs again.

What if the same problem happens again?

If you get another virus in the future which breaks your file extensions and is preventing you from opening programs, simply run PC MightyMax File Extension Repair again. Even when your other programs will not work, PC MightyMax File Extension Repair will be able to run and fix your computer.
