AvirTrWarning.dll is a library file that contains malicious code, which implements main parasite functions. This file usually needs to be loaded by executables or other pest files. However, some threats inject AvirTrWarning.dll in the system, so it works as an independent component, for example, as a harmful web browser plugin or hidden system service.
The AvirTrWarning.dll file is installed and used by AntivirusTrigger.
In most cases AvirTrWarning.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 AvirTrWarning.dll file must be manually deleted. If you cannot erase it, consider using recommended spyware removers, which will get rid of AvirTrWarning.dll and associated parasites for you.
Sometimes a presence of AvirTrWarning.dll does not indicate that your computer is infected. It can be an essential system file or a file installed by harmless legitimate software and therefore may not pose any threat to your privacy and the system. Although such cases are quite rare, you should thoroughly examine AvirTrWarning.dll before completely deleting or leaving it in the system.
