Troj/Spyre-C is a Trojan for the Windows platform.
The Trojan displays advertisements and fake security warnings in an effort to
promote traffic to a specific website.
Troj/Spyre-C may create registry entries under HKLM\Software\AntivirusGold.
Troj/Spyre-C copies itself to the Windows system folder as winnook.exe and sets
the following registry entry in order to run each time a user logs on:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Intel system tool
"<Windows system folder>\winnook.exe"
The Trojan drops a file named desktop.html to the Windows folder which contains
the fake security alerts and prompts to visit the remote website. The following
text appears in the message:
WARNING! YOU'RE IN DANGER! ALL YOU DO WITH COMPUTER IS STORED FOREVER IN YOUR
HARD DISK. WHEN YOU VISIT SITES, SEND EMAILS... ALL YOUR ACTIONS ARE LOGGED.
AND IT IS IMPOSSIBLE TO REMOVE THEM WITH STANDARD TOOLS. YOUR DATA IS STILL
AVAILABLE FOR FORENSICS. AND IN SOME CASES FOR YOUR BOSS, YOUR FRIENDS, YOUR
WIFE, YOUR CHILDREN.
Troj/Spyre-C may also download and execute files from a remote site.
