.VIR File Extension


File Type Virus-Infected File
File Format File
Common? No
File Description File infected with a computer virus that has been renamed by an antivirus software program, such as Symantec's Norton AntiVirus or Avira AntiVir; the ".vir" extension is typically appended to the filename (i.e. program.exe -> program.exe.vir) to indicate the file is a virus and to prevent it from being executed.

Removing the ".vir" extension may allow you to open the file, which may also enable the virus to run; therefore, you should not open VIR files manually; instead, it is best to let the antivirus program locate and remove VIR files.
Program(s) that open vir files Mac: Symantec Norton AntiVirus for Macintosh; Should not be opened manually
Windows: Symantec Norton AntiVirus for Windows; Avira AntiVir; Should not be opened manually
