The Quad-Cities OnlineŽ technical department has a upgraded our mail server to have a very nice filter in place to help prevent the spreading of viruses with common subjects and common senders. This new filter is another added bonus to being a Quad-Cities OnlineŽ Customer and is free for anyone with a qconline address.
If you try to send out (or someone tries to send to you) a message that has a subject that is the same as a common virus subject line, you or that person writing you will receive a 554 filter error. If you receive this error, you will want to change the subject of your message, so that the message will get past the filters. If you change the subject and it doesn't help, or you have sent nothing and are getting this error, you may have a virus on your machine that is trying to reproduce itself at your machine's expense. You should then check your machine to verify it does not have a virus already.
If you attempt to send an E-mail which contains a known virus to someone or someone sends one to you, then you will receive an E-mail notice from email@example.com letting you know. This message will let you know who is sending the virus (if it is you or someone to you). It will also let you know which virus is being sent. Along with this message, you will receive an attachment to this message from our system letting you know what the original message said.
This filter is set up as a first line of defense, but in no way should it be your only line of defense. It will only filter known viruses, and will not be able to catch the latest and greatest viruses as soon as they come out. Viruses can get into your machine via chat programs, floppy disks, and websites as well. To protect yourself better, take action.
1) Make sure you have good anti-virus software.
2) Make sure you are using it.
3) Make sure you have the current update.
4) Don't even consider opening any unknown files until you have done those first three things.
