The stdafx.cpp file is an essential part of a particular parasite and therefore is responsible for the pest's malicious activity. Exact purposes of stdafx.cpp depend on the related parasite's type and carried payload. Some threats can use stdafx.cpp to serve annoying pop-up advertisements or store certain configuration settings, while others need it to corrupt files, steal user confidential information or run a spreading routine. In any case, DO NOT open this file!
The stdafx.cpp file is installed and used by keylogger
Nano. It is also related to other parasites such as
DSNX 0.4b and
Moses. These threats can use stdafx.cpp for different purposes, as the file's functionality depends on a particular parasite it belongs to.
Sometimes a presence of stdafx.cpp 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 stdafx.cpp before completely deleting or leaving it in the system.
