Virus Checker by John Veldthuis
>>> WARNING VIRUS CHECKER V6.59 & V6.60 ARE FAKE BE VERY CAREFULL <<<
This is probably the most famous virus checker on the Amiga, maybe even
the best? If your asking what a virus is or what a virus checker is then
you should get this program now as you will most likely need it.
What is a Computer Viruses ?
A computer virus is usually a small program than can duplicate itself and
copy itself to many different floppy disks, hard disks, in fact most
mediums that are writeable can be infected with a virus. During the
process of copying itself the virus usually causes some sort of damage to
your files, this could be deleting a file, formatting your hard drive or
some other malicious act. The only way to stop this from happening is to
find the virus and delete it. This is where Virus Checker comes in.
Types of Virus
Boot-Block virus.
This virus is the most common on the Amiga and is very easy to detect. A
Boot- Block is the section of a floppy disk that holds information for
Amiga-DOS. This information tells Amiga-DOS what type of disk and file
system is in use. What a Boot-Block virus does is to amend itself to the
Boot-Block so when your disk is booted the virus is loaded straight into
ram. The virus then sits in ram and waits for a different floppy disk to
be inserted in to a drive. When one is inserted the virus then writes
itself to that disk. So in time your entire floppy collection could
become infected with viruses. After you use the infected disk(s) a few
times the virus usually destroys some data on that disk thus making it
unusable.
File virus/link virus.
A file virus is a file that when run will infect other files on your hard
drive or floppy disks. These files when infected are still usable as
standard but carry a deadly secrete. Most file virus carry a
timer/counter and when they have been activated a certain amount of times
they will destroy data, format hard drives etc. These viruses are very
hard to spot unless you use a good virus checker.
Trojan Virus
This is a program that looks and works like it should but in time it
becomes a active virus. Most do strange things to the floppy drives and
hard drives. An example of this is a Pirate copy of DiskSalv V3 that
works fine but after a few goes it will format you HD. I MUST STATE THAT
DiskSalv V3 IS A BRILLIANT PROGRAM AND IS WORTH ITS WEIGHT IN GOLD AND
THE VERSION WITH THE TROJAN VIRUS ON HAS NOTHING TO DO WITH THE
PUBLISHERS, but if you haven't got the original then in my eyes you
deserve what you get.
Virus Checker is (as its name implies) a virus checker/killer. What this
program does is to scan your floppy disks, hard drives etc for viruses.
The way it does this is to load and examine each and every file to see if
it is a virus or to check if the file is infected with a virus. If it
finds a virus it will then inform you and either delete the virus and/or
fix the infected file. Virus checker will also check packed files and if
you are a registered user it will also check .lha files.
On starting Virus Checker the first thing the program does is to check
your memory to see if any viruses are there it will then check you hard
drives and floppy disks for viruses if you ask it to. Alternatively you
can tell it to check your hard drives and floppy drives as soon as it is
activated. Virus Checker comes with full AmigaGuide documentation
listing and explaining all the option of the program as well as a list of
the Viruses it knows and can deal with.
Well thats about it but incase you are wondering where most viruses come
from, they can usually be found on most Pirate software, and as I said
before if you use Pirate software then you deserve all you get.
And to those people who say 'I use loads of Pirate software and have
never had a virus', well your just kidding yourself as you don't know if
you have a virus till its too late.
Madness
