The program is designed to be small, safe, and easy to use. When Virus-Interceptor is installed in memory, it will constantly check programs that are run for virusinfection. If a virus is detected in the code, the program will be aborted before it had a chance to start! Virus-Interceptor will also check the memory at regular intervals. If a virus is detected in memory it will be removed in a safe way. Virus-Interceptor has an unique feature: It will detect any new, previously unknown link-viruses in a program that was crunched with any of the known crunchers! Virus-Interceptor requires an absolute minimum of user-interaction. You just start it up, and then you can go on doing whatever it is you usually do with your computer. Virus-Interceptor will only disturb you if it finds a virus. Virus-Interceptor will communicate to you via DisplayAlert's, ie. those wellknown black screens with a yellow flashing border. Virus-Intercepor 1.13 knows 85 viruses, not counting clones. -Interceptor package to suit their VirusKiller disk. Requirements Virus-Interceptor will work on any Amiga with OS 2.0, OS 2.1 or OS 3.0. Virus-Interceptor has been successfully tested with 030 and 040 processors. Using Virus-Interceptor There are a number of ways to start Virus-Interceptor. First of all you can click at the VI icon. It will use the program IconX to run Virus-Interceptor. IconX can be found in the c: drawer of your Workbench disk. The second way is to start up CLI, and then 'cd' to the directory where you keep Virus-Interceptor, and then type: 1> Virus-Interceptor Virus-Interceptor will then install itself, and that's it! It will auto-detach completely from the CLI, so you can close the CLI window. From now on Virus-Interceptor will communicate via alerts. The ideal thing is to put Virus-Interceptor in your startup- sequence, thus making it start up automatically every time you reboot. Load the file S:User-Startup into your favourite editor and insert "C:Virus-Interceptor >NIL:" at the beginning of the file, that is, if Virus-Interceptor is in the C: directory. >NIL: will get rid of the startup message. Virus-Interceptor patches the DOS-routines LoadSeg(), NewLoadSeg() and InternalLoadSeg(). The patching and the patch-removing is done as system-friendly as possible. You may wish to exit Virus-Interceptor, in out-of-memory situations for example. Just run Virus-Interceptor again, and it will exit in a second. VI will tell you it's leaving by flashing the screen and/or beeping (depending on your Sound preferences). You will also be told if a problem occurs, like if an other program is preventing VI from exiting. What if I find a virus?" If a virus is detected in an executable program or in the memory, you will be presented with an alert, telling you about it. It will look something like this: ********************************************************************** * * * Virus-Interceptor Alert: * * * * The file c:Strange is * * really the VeryBad file virus! * * * * Execution aborted. * * * ********************************************************************** Click a mouse-button and the flashing screen will be gone. The virus has been stopped in its tracks... But the virus will still be (in) that file c:Strange. Now you have to remove it from the disk. There are several excellent, intuitionized virus- killers that will do that for you. The most wellknown are BootX, VirusZ, and Virus_Checker. If you haven't got any of them, contact your regional SHI Centre and they will help you. If Virus-Interceptor said that the virus was 'unknown', there's one more thing you'll have to do: Send it to me! It might be a completely new virus, not yet recognized by any virus- killer. If you send the infected file to me on a disk, I will analyze it and include it in the next release of Virus-Interceptor! Thanks!
