Dialers (DIALERS) 
Certain services available in the Internet have to be paid for. They are invoiced in 
Germany via dialers with 0190/0900 numbers (or via 09x0 numbers in Austria and 
Switzerland; in Germany, the number is set to change to 09x0 in the medium term). 
Once installed on the computer, these programs guarantee a connection via a suitable 
premium rate number whose scale of charges can vary widely. 
The marketing of online content via your telephone bill is legal and can be of advantage 
to the user. Genuine dialers leave no room for doubt that they are used deliberately and 
intentionally by the user. They are only installed on the user’s computer subject to the 
user’s consent, which must be given via a completely unambiguous and clearly visible 
labeling or request. The dial-up process of genuine dialers is clearly displayed. Moreover, 
genuine dialers tell you the incurred costs exactly and unmistakably. 
Unfortunately there are also dialers which install themselves on computers unnoticed, 
by dubious means or even with deceptive intent. For example they replace the Internet 
user’s default data communication link to the ISP (Internet Service Provider) and dial a 
cost-incurring and often horrendously expensive 0190/0900 number every time a 
connection is made. The affected user will probably not notice until his next phone bill 
that an unwanted 0190/0900 dialer program on his computer has dialed a premium rate 
number with every connection, resulting in dramatically increased costs. 
We recommend that you ask directly your telephone provider to block this number range 
to be immediately protected against undesired dialers (0190/0900 dialers). 
Games (GAMES) 
There is a place for computer games - but it is not necessarily at work (except perhaps in 
the lunch hour). Nevertheless, with the wealth of games downloadable from the 
Internet, a fair bit of mine sweeping and Patience playing goes on among company 
employees and civil servants. You can download a whole array of games via the Internet. 
Email games have also become more popular: numerous variants are circulating, ranging 
from simple chess to "fleet exercises" (including torpedo combats): The corresponding 
moves are sent to partners via email programs, who answer them. 
Studies have shown that the number of working hours devoted to computer games has 
long reached economically significant proportions. It is therefore not surprising that 
more and more companies are considering ways of banning computer games from 
workplace computers. 
Jokes (JOKES) 
Jokes are merely intended to give someone a fright or provide general amusement 
without causing harm or reproducing. When a joke program is loaded, the computer will 
usually start at some point to play a tune or display something unusual on the screen. 
Examples of jokes are the washing machine in the disk drive (DRAIN.COM) or the screen 
eater (BUGSRES.COM).
