The F-Fizzer utility disinfects computers infected with Fizzer
worm.

Disinfection procedure should be as follows:

1. Unpack the F-Fizzer utility from the provided ZIP archive 
either with WinZip or PkUnzip utilities. A trial version of 
WinZip archiver can be downloaded from the following website:

http://www.winzip.com/ddchomea.htm
                                   
2. Run the unpacked F-Fizzer.exe file from a hard disk to 
eliminate Fizzer worm infection. You can run the utility by 
either doubleclicking on it from Windows Explorer or you can 
start it from a command interpreter (COMMAND.COM or CMD.EXE) by 
typing its name at command prompt and pressing 'Enter' (for 
advanced users).

First the F-Fizzer utility will kill Fizzer worm's processes in 
memory. Then the utility will scan your hard drive for infected 
files and delete them.

3. Reboot a system. After restart your system should be clean.

If you have F-Secure Anti-Virus installed, the utility will 
temporarily disable on-access scanner to be able to disinfect 
your system. After the utility completes disinfection, it enables 
on-access scanner.

You can get a trial version of F-Secure Anti-Virus and the latest 
updates for it from our website:

IMPORTANT NOTES
---------------

If a computer with Windows NT, 2000 or XP operating system is being 
disinfected, please log in as Administrator or as a user with 
local admin rights, otherwise the F-Fizzer utility might not 
disinfect the system correctly.

If you have Windows ME or XP, it is recommended to disable System 
Restore feature of these operating systems to prevent your 
computer from re-infection with Fizzer worm. The fact is that 
System Restore feature of these operating systems might save the 
infected file into the special folder and copy it back to a hard 
drive it every time it's been deleted by F-Fizzer utility. The 
instructions on how to disable System Restore feature are here:
