What is defext.dll? Should I remove it?

by Ugnius Kiguolis - -

defext.dll is a library file that is responsible for implementing main parasite functions and running its destructive payload. The defext.dll file cannot run by itself and therefore needs to be loaded with the help of some executable files. However, certain parasites reconfigures the operating system or installs defext.dll as a plugin, so that the system or certain applications automatically load it on startup.
The defext.dll file is installed and used by Defense Center.
In most cases defext.dll is responsible for all the harmful actions the pest takes. Removing this file will immediately terminate the parasite or partially disable it. That is why the defext.dll file must be manually deleted. If you cannot erase it, consider using recommended spyware removers, which will get rid of defext.dll and associated parasites for you.
Please note that the defext.dll file actually may be a fully legitimate part of the operating system or legitimate software. Often parasites use files with unsuspicious names, but malicious functionality. You should always carefully check the file before deleting it. It may not be related with malware, but can be required by your essential programs to work properly.
