what with a dozen or more very<br />

good virus protection systems<br />

around, all of them free.<br />

The most famous is Steve<br />

Tibbet's VirusX, and here's the<br />

very latest official upgrade, version<br />

4.01, direct from Canada,<br />

A lot of changes have been made<br />

since 4.0, although experienced<br />

VirusX users will only notice one<br />

difference in operation. The most<br />

important change is that the program<br />

is now compatible with<br />

<strong>Amiga</strong>DOS 2.0. New users stay<br />

around for a wh ile and I'll explain<br />

the best ways of using the program.<br />

See the release notes on the cover<br />

disk for all the details.<br />

By far the safest way of using<br />

VirusX is to launch it from your<br />

startup-sequence somewhere just<br />

before LoadWB. VirusX first checks<br />

memory to see if anything is there<br />

that shouldn't be there, then it will<br />

— Are you a budding musician look-<br />

a moody little ditty called Marilyn ing for fame and fortune? If so,<br />

by Steve Cooper of Rochester in perhaps the <strong>Amiga</strong> <strong>Computing</strong><br />

Kent.<br />

cover disk can give you a little<br />

Steve uses Noisetracker v1.0 to push up the ladder, You never<br />

create his tunes. He's a self- taught know who might be listening to<br />

musician, playing drums and guitar.<br />

and has been 'tracking for 18<br />

months or so now. After a<br />

rt<br />

day<br />

working in the local Nursery (that's<br />

little plants, not little pests) Steve<br />

likes nothing more than to sit<br />

down at his A500 and create tunes tiliol• 11<br />

using his own sound samples. „<br />

•<br />

The tune we have here uses<br />

II 1 I<br />

fairly standard samples — experienced<br />

'trackers will no doubt H<br />

recognise one or two of them — but 1111<br />

Steve also produces compositions o<br />

he calls "soundscapes" made up of 1111<br />

synthesised animal noises and<br />

snatches from films.<br />

t<br />

Marilyn, on the other hand, is an i<br />

excellent example of how to create o<br />

a really together tune using very<br />

few samples. A pulsating bass line<br />

plus clever slide and echo effects o<br />

on the guitar solo show off Steve's<br />

expertise with Noisetracker. One or<br />

two people I've played it to reckon<br />

the female gasp spoils it, but I<br />

guess that's just a matter of taste.<br />

open a small window on the<br />

Workbench title bar and sit in the<br />

background twiddling its bytes<br />

until you stick a disk in any drive,<br />

whereupon it will check the bootblock<br />

of said disk and report on<br />

what it finds.<br />

If this is what you intend to do,<br />

and I strongly suggest you do, then<br />

make sure you copy the VirusX<br />

program into the C: directory•of<br />

your everyday boot-up disk.<br />

The one thing VirusX can't<br />

check for are viruses that attach<br />

themselves to files. Which is why<br />

another program, Kill Virus (abbreviated<br />

to KV). is distributed in the<br />

package.<br />

Again, you should copy KV into<br />

the C: directory of your boot-up<br />

disk so the command is available if<br />

you should need to use it. Unlike<br />

VirusX, KY cannot be run from the<br />

workbench, which is why there is<br />

no icon for it in the VIRUSX401<br />

drawer. Double click on KVDOC<br />

for details of how to use Kill Virus,<br />

The full documentation for the<br />

previous release of VirusX is on<br />

the disk and is all relevant to the<br />

current version. See the 4.01<br />

release notes to find out about the<br />

new extras.<br />

your music. For instance, Howie<br />

Davies got commissioned by a software<br />

house after Rock The House<br />

appeared on the cover disk.<br />

Keep cool<br />

SOME progrlIns notably those<br />

that create recoverable ram<br />

disks, take over the <strong>Amiga</strong>'s<br />

CoolCapture vector for their<br />

own use. If you are running<br />

such a program, like RRD for<br />

example on last months cover<br />

disk, then VirusX will immediately<br />

warn you that the<br />

CoolCapture vector is not zero.<br />

Alas, some viruses use this<br />

vector to hide themselves and<br />

stay alive through a warm reboot,<br />

but if you are sure that<br />

your CoolCapture vector is<br />

being used by something you<br />

are running and not by a virus,<br />

then it is quite safe to click<br />

"No" when VirusX asks if you<br />

want to reset it.<br />

You can prevent VirusX from<br />

checking the CoolCapture vector<br />

by using the -c option in the<br />

command line.<br />

VIRUSX 4.01 is freely distributable<br />

but remains<br />
