Dialers change the number used for dial-up internet access to a
premium-rate number.
Dialers are not always malicious. Legitimate companies that offer downloads or games
may expect you to use a premium-rate line to access their services. A pop-up prompts
you to download the dialer and tells you how much calls will cost.
Other dialers may install themselves without your knowledge when you click on a
pop-up message (for example, a message warning you about a virus on your computer
and offering a solution). These do not offer access to any special services – they simply
divert your connection so that you access the internet via a premium-rate number.
Broadband users are usually safe, even if a dialer installs itself. This is because
broadband doesn’t use regular phone numbers, and because broadband users don’t
usually have a dial-up modem connected.
Anti-virus software can detect and eliminate Trojan horse programs that install dialers.
