Here are all the steps in detail and in one place, for getting Alien Virus to run (thanks to DosRaider!), for anyone who is technically-challenged like I am:-

ALIEN VIRUS : HOW TO INSTALL

Follow the instructions EXACTLY:-

Make a folder C:\oldgames\virus
Unzip Alien Virus zip-file into the “virus” sub-folder

FIX THE CONFIG FILE AS FOLLOWS:_
Right-click on file AV.CFG
Select Open with…
Choose “select the program from a list..”
Choose to open it with Notepad (browse to Notepad, then click on it)
CAREFULLY change the contents to read EXACTLY as follows:-
SourcePath = c:\virus
(leave “InstallationType = 1” exactly as is, do not alter it)
Click x at top right of Notepad window, then choose “yes” to savew the changes

RUN THE PATCH FROM WITHIN DOSBOX AS FOLLOWS:-
Open DOSBox
Type as follows:-
mount c: c:\oldgames and hit enter
c: and hit enter
cd\virus
avpatch
DOSBox will ask “Do you want Wanna Patch AV.EXE now? (y/n)
type y
DOSBox responds “Patch complete, Alien Virus …was changed”

SET UP THE SOUND (STILL WITHIN DOSBOX)
(you should still be in the “virus” sub-directory in DOSBox)
Type setsound and enter
Select Soundblaster 16 (choice 3)
Select I/O = 0x220 (choice 2)
Select IRQ = 7 (choice 4)
Select DMA = Channel 1 (choice 2)
The computer will respond C:\ virus

RUN THE GAME:-
While still in the same “virus” sub-directory in DOSBox,
Type av and hit enter.
Two screens come up, then the av-logo/ title screen comes up.
Right-click your mouse to start the game.


To run in future (now you have set everything up):
Open DOSBox
Mount c: c:\oldgames
c:
cd\virus
av
Right-click on av-logo / title screen
