NOTES:
This is the Trend Micro detection for malicious Java class files used as a component of other malware. Once the user accesses a malicious site, this malicious script is executed.
This file may download a possibly malicious file into the system. It saves the downloaded file as %User Temp%\best.exe. However, the URL where the file is downloaded is not found in the code of the malicious Java class file.
(Note: %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000, XP, and Server 2003.. %Temp% is the Windows Temporary folder, which is usually C:\Windows\Temp or C:\WINNT\Temp.)
