This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.
Detection was added to cover a 32 bit PE file having a random 8 byte hexadecimal name (Example 987AA928.exe). The file is internally compressed with the FSG Packer and is usually around 8 KB in size.
Upon execution the Trojan adds a HTML page in %windir% as index.html (also detected as Raze Trojan). The HTML page is then installed as desktop wallpaper that displays a fake warning that system is infected with spyware, keyloggers and adult content. It prompts user to download Raze AntiSpyware to protect themselves against these threats.
So this is not a true warning message upon a virus/trojan intercept, it's html page filling the complete screen having the fake message painted in it
Manual execution of the binary starts the infection, there's no exploit associated with this file.
Use current engine and DAT files for detection and removal.
Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).
