@Latest Hot News: FreeFixer should be able to delete dmwu.exe, however I can not recommend to remove dmwu.exe since I don't know what the file does. dmwu.exe might be part of the IncrediBar or Incredimail software. The anti-virus scan done by virustotal did not indicate any malicious about the dmwu.exe file.

Are you experience some problem related to dmwu.exe, such as error messages, crashes, or have you found some other information that suggests that removal of dmwu.exe is recommended?

@bhavik: The "has encountered a problem and needs to close" error message is reported when dmwu.exe crashes. A crash typically occurs due to a bug in the executable file, in this case dmwu.exe.

I see two solutions:

1) Contact the developer of dmwu.exe and request an update where the bug has been fixed.


2) Do some digging to find out which software product dmwu.exe comes with and if you don't need that software, just uninstall it. Since dmwu.exe is digitally signed by Perion Network I would guess that dmwu.exe comes with IncrediBar, Incredimail or some of the other Perion products. Do you have any of these installed on your computer?

When does the "has encountered a problem and needs to close" error message pop up?
