If you receive this message form a friend of yours, what do you do?
----------------------------------------------------------------
Hello! I just got this letter from my friend and yes I had the virus as well please follow the directions to see if you have the virus and then follow the directions to get rid of it. Like my friend I am sorry that I passed it along as well.
Dear All: We received a virus on a message. I followed the instructions below and found that it had been spread to our computer. I followed the instructions and located the virus and was able to delete it. The bad news is that you probably have it, as you are in My Address book! More bad news is that my anti virus program did not detect this virus. The virus lies dormant for 14 days and then "kills" your hard drive.
Here is what to do. If you follow the instructions and then see that you have the virus, you need to send a similar e-mail to everyone in your address book.
Remove the virus by following these steps:
1. Go to "Start." Then to "Find" or "Search".
2. In the "Search for files or folders" type sulfnbk.exe -- this is the name of the virus.
3. In the "Look in" section, make sure you are searching Drive C.
4. Hit "Search" or "Find".
5. If your search finds this file, it will be an ugly blackish icon that will have the name sulfnbk.exe. DO NOT OPEN IT! If it does not show up on your first "Search", try a "New Search."
6. Right click on the file -- go down to "Delete" and left click.
7. You will be asked if you want to send the file to the Recycling Bin -- say "Yes".
8. Go to your Desktop (where all your icons are) and right click on the Recycle Bin and either manually delete the sulfnbk.exe program or empty
the entire bin.
9. If you found the virus on your system, send this or a similar e-mail to all in your address book because this is how it is transferred.
Sorry for the trouble and my apologies for having unwittingly "infected" you. You'll want to check for this virus again for the next couple days
until everyone in your address book has seen it and deleted it, otherwise, being in their address book, your PC will get infected all
over again so don't forget to check!
