Warning about Melissa Virus in .rtf files
We have learned that Melissa virus has recently been
spreading again and may not be detected by any
antivirus software including Norton AntiVirus. It is
important to note that this is not a new variant of the
Melissa virus.
What we have confirmed a Word document infected by
W97M.Melissa.A with the file extension of .rtf is being
sent out to many users though email. These documents
are not actually in .rtf format files as the file
extension name suggests, but is actually a Word format
file that has had the file extension name renamed to
.rtf. If the antivirus software is not configured to
scan the .rtf file extension, the virus will not be
detected.
To protect yourself from this virus, Symantec AntiVirus
Research Center recommends to update the configuration
in Norton AntiVirus to include the .rtf file extension
as well as the following file extensions in the Scanner
and Auto-Protect options.
Complete List of File Extension Recommended for Scanning:
386, ADT, BIN, CBT, CLA, COM, CPL, CSC, DLL, DOC, DOT,
DRV, EXE, HTM, HTT, JS, MDB, MSO, OV?, POT, PPT, RTF,
SCR, SHS, SYS, VBS, XL?
To add .rtf to your list of Program Files to be scanned
in NAV 95 and NAV NT:
1. Open Norton AntiVirus
2. Click Options. The Options dialog appears.
3. Click the Scanner Tab.
4. Click Select... in the "What to scan" section.
NOTE: This button is dimmed (greyed out) if you have the All Files radio button
selected.
The Program File Extensions dialog will appear.
5. Click New... .
6. Type RTF in the resulting box and then click OK.
7. Click OK in the Options dialog.
