Legal Stuff -------------- The entire XVS software package is written and copyright © 1997-99 by Georg Hörmann. No parts of this package may be altered by any means (this includes editing, reprogramming, crunching, resourceing etc.), except archiving. The author is in no way liable for any changes made to any part of the package, or consequences thereof as he is in no way liable for damages or loss of data directly or indirectly caused by this software. Neither fees may be charged nor profits may be made by distributing this piece of software. Only a nominal fee for costs of magnetic media may be accepted, the amount of DM 4/US $3 shouldn't be exceeded for a disk containing XVS. Non-commercial CD manufacturers are allowed to put the package on their compilations, too. Outside a single machine environment, you are not allowed to reproduce single parts of the package, but you have to copy it completely. 2. Installation --------------- The xvs.library contains all the virus recognition and removal code that was formerly included in VirusZ. This step has been taken for one major reason: VirusZ can be updated fast without releasing the whole package every week by releasing a new library version. So simply install the library in this archive to your LIBS: drawer to get 100% protection against the latest viruses. The following chapters contain information mostly for programmers who want to write their own viruskillers, so you can skip this if you are not interested! 3. Why Another Library? ----------------------- As most of you may have noticed, I don't have much time at the moment to add all the features you desire to my viruskiller VirusZ II/III. On the other hand, there are a lot of talented coders out there who might have the time to write a really good viruskiller environment, but don't have all the viruses to add them or are not willing to torture themselves with analysing all those little bastards. That's the point where xvs.library comes in. With this library I want to give you a powerful tool to detect and eliminate all sorts of viruses. All you have to do (and that's still enough, believe me ;-) is to submit the files, sectors or bootblocks you want to have tested to xvs.library. In other words: You design a GUI with all the features that are required nowadays (ARexx, Locale, etc.) and I support you with my antivirus knowledge of the last 7 years!! Certainly VirusZ will be developped further-on in the near future, but it's always good to have some new rivals that give you new inspiration ;-) 4. Features ----------- Currently xvs.library offers you the following functions: a. Detect bootblock viruses and install clean bootblocks instead. b. Detect manipulated disk sectors and repair them if possible. c. Detect infected files and repair them if possible. d. Scan all memory regions for active viruses and remove them if any. This should be all you need to put up a complete viruskiller. About further functions you have to think yourself. 5. Hopes And Fears ------------------ I thought quite a long time about the release of XVS to the public as it might be some kind of 'sudden death' to my own project VirusZ. All the antivirus knowledge of VirusZ has been exported to this library. Anyone with just enough programming skills can easily beat the features of my own antivirus program by using XVS. But on the other hand, antivirus work is always some kind of service to the public and shouldn't be overridden by selfish thoughts. And as I won't be able to keep up that service in the far future, I will at least give my support to the ones who follow me. 6.
