File is a virus, worm, or other malware file
This error can be generated by a file that is a virus, worm, Trojan, or other malware file. Often, this will be caused because the virus scanner installed in the computer will not allow the file to be installed or run. Try scanning the file to verify it is not a virus or infected.
If the file has been checked and is clean, it is still possible that the virus protection program or another program installed on the computer is causing issues during the install or execution of the program. Boot the computer into Safe Mode and try running the program; booting the computer into Safe Mode will make sure nothing is running in the background that could be causing this issue.
