Files Infected with Worms
A computer worm is a self-contained program (or set of programs) able to spread
functional copies of itself or its segments to other computer systems. The propagation
usually takes place through network connections or email attachments. Worms are
uncleanable because the file is a self-contained program.
Solution: Trend Micro recommends deleting worms.
Write-protected Infected Files
Solution: Remove the write-protection to allow OfficeScan to clean the file.
Password-protected Files
Includes password-protected compressed files or password-protected Microsoft Office
files.
Solution: Remove the password protection for OfficeScan to clean these files.
Backup Files
Files with the RB0~RB9 extensions are backup copies of infected files. OfficeScan
creates a backup of the infected file in case the virus/malware damaged the file during
the cleaning process.
Solution: If OfficeScan successfully cleans the infected file, you do not need to keep the
backup copy. If the computer functions normally, you can delete the backup file.
Infected Files in the Recycle Bin
OfficeScan may not remove infected files in the Recycle Bin because the system is
running.
Solutions:
For computers running Windows 2000/XP/Server 2003 with NTFS File System,
perform the following steps:
1. Log on to the computer with Administrator privilege.
2. Close all running applications to prevent applications from locking the file, which
would make Windows unable to delete it.
