View source for When I start Total Commander, I get a warning within the first few seconds that totalcmd.exe is defective, probably caused by an unknown virus. However, my virus scanner doesn't find a virus!

'''A''': Total Commander contains a checksum function, which checks at every program start whether the program has been modified. If you receive the above message, the checksum function has detected a modification. This may have several reasons:
# In most cases this is caused by a new virus which is unknown to your scanner. You should immediately get the latest antiviral data for your scanner, and/or a second scanner.
# Total Commander is located on a (network) drive in a directory to which you only have execute rights, but no read rights. Total Commander needs read rights too.
# If the error only occurs from time to time, and you also have some inexplicable crashes, the reason is most probably a defective memory module (RAM).
# After the installation of a new version of Total Commander, it can happen that parts of the old program are still in cache, which can cause this error. After a reboot, the error should disappear.
