WARNING FROM JERRY BRASSEUR (4-08)
The Anti-Virus company Sophos has detected and confirmed the existence of a new malware targeting Macintosh users.

It is classified as a Trojan horse as it comes into your computer hiding in another file.

If you purchased the Sophos program with us and have kept it updated, you will have the detection installed for this malware.

If you did not purchase Sophos, you will have to be alert for a pop-up program (shown in the article below) on your computer called the Imunizator.

It is not a malicious Trojan. It will not do anything to your computer!

It is attempting to sell you bogus, unnecessary software program that is useless.

I have attached the information below from Sophos. It is a pdf file which you should be able to read.

It has a picture of the program's window as you would see it on your screen if it gets into your computer.

Just quit it, find it, and delete it!!

If you have Sophos installed, it will warn you of the Trojan if it is detected.

If you want to read more about this Trojan, I have listed a link to the Sophos and Computerword articles.

Sophos is warning that this is just the beginning of attacks on Macintosh computers.

Hope this helps you be warned in advance!!

Recommended Settings for Sophos Anti-Virus by Jerry Brasseur
Saginaw Macintosh Users Group

After installing Sophos, you may open the preferences either from the shield in the top menu bar or from System Preferences under the "Other" section. This is the window you will see ---->

Your first step is to click the lock at the bottom of the window and type in your computer's password. Make sure the "Start" button is grayed out which indicates it is running.
Change "General" to "Scanning Options" and check all three choices.
Change "Scanning Options" to "Disinfection". You must decide what you want Sophos to do when it finds and infected file. For most users, deleting the file is the probably the best choice. (Personally, I want to see what the file is, where it came from, etc., so I move it to my Documents folder, then manually delete it after examining it.) I leave Exclusions "blank" because I want everything scanned.
Change "Disinfection" to "Desktop Alerts". I only have "Virsues" checked as you will find Microsoft and Adobe programs will give you error messages because of their security. Sophos cannot open them to scan them due to the way they are programmed. I don't Log because those log files can become very large after a short period of time. If you are seeing lots of warnings, then turn on the Logging so you have a record of the occurences. Click on the "Set" button at the bottom before continuing on. Click on the center "Notification" button. This is intended for use on a server so that any notifications are sent to the person running the server network. It is not necessary for use on one computer.
Click on the Right button -- "AutoUpdate". Network settings should be selected. Click on the "Primary Server" button. Click on the "Sophos" button. Type in your Sophos user name and password that were sent to you. All of the other choices are for local networking. Leave them with their default settings.
Click on "Scheduling". This determines how often you want Sophos to update the program and the virus definitions via the internet. My choices are both buttons selected and every 30 minutes. If you are on dialup, you may want this done fewer times.
"Desktop Alerts", I have it unchecked as these are only messages about its updating procedure, not virus notifications. It just creates another window that you will need to close. If Sophos cannot connect to Sophos' server for updating, you will see a little red warning on the shield in the menu bar.
This "Logging" is only for the "AutoUpdate" and I really have no need to keep track of it. I have every choice unchecked. Finally, click the "Set" button at the bottom so any/all of your changes are saved.
Now that you have all of your Preferences selected, pull down the top menu bar shield and choose "Open Sophos Anti-Virus". You will get this window --->

All hard drives connected to your computer will be in the top pane. Any drives that you want scanned should have a little green light in front of it's name. You can turn these on or off. The bottom pane shows the definitions that will be used to check your hard drives. Click the green arrow to begin scanning. This will begin an initial scan that does not need to be repeated as Sophos will take over the continuous scanning after you are sure your drives are clean of any viruses. This may take several hours depending on the size of your drives.
In the upper corner, click on the left preference icon.
Click on "Scanning Options" and select all three check boxes.
Click on "Disinfection". Choose your settings. If you want any viruses immediately deleted, make that choice. (My choice is to move them so I can investigate what they are.)
I have "Reporting" turned off. It's your choice.
I have only "Viruses" checked as I know Microsoft and Adobe will trigger the Error alert and I'm not concerned about them. The last choice is "Logging". This is something that could be useful the first time you scan all of your hard drive files. You can select where you want the log file saved. After the initial scan, Sophos will run in the background and you will not be bothered by it unless it discovers a virus that has just been added to your hard drive. It will warn you!
