If you are a Virgin Media Pay As You Go or 24seven customer, your computer will connect to the Internet over the telephone network by using a "dialler" - a small program which dials in to Virgin Media using the telephone number first provided when you set up your connection.
"Rogue diallers" are programs which attempt to replace your original dialler settings with a premium rate number, allowing unlawful third parties to make a profit each time you connect to the Internet.
How does a rogue dialler get onto my computer?
Typically, rogue diallers attempt to install themselves on your computer using one of two methods:
- Malicious emails which contain attachments - these emails will encourage you to open their attachment by deception, and when you do the rogue dialler is installed.
- Disreputable websites - some websites will unexpectedly ask you to install software in order to view their content, often via a pop-up window.
How can I protect myself from rogue diallers?
If you are using PCguard, it's important that you protect your computer from attack. You can do that by following the advice below:
- Be wary of attachments
Virgin Media do not send emails with attachments to our customers. Before opening any attachment, always ensure that it is legitimate.
- Be wary of websites asking you to install software
Never install software unless you are completely sure it is from a reputable source.
- Use an up-to-date anti-virus program
Anti-virus programs such as Symantec AntiVirus will scan files as they are opened and will check them for viruses. These programs are also regularly updated with information about new viruses, so it's essential to keep your program up-to-date to maximise protection.
- Use a personal firewall
A firewall, such as Virgin Media’s PCguard, is a piece of software that can help prevent hackers from accessing your computer via the Internet. In simple terms a firewall can be viewed as being the lock and chain on your front door. When you are surfing on the Internet your door is open and the chain (the firewall) prevents intruders (or hackers) getting inside.
- Disconnect the phone cable from your computer when not connected
This eliminates the risk of traffic getting through to your computer when you are not connected to the Internet.
- Regularly update your Windows/Mac software
Microsoft and Apple review their software regularly and release updates or 'patches' to fix any known security issues, which viruses can exploit. In order to help keep your computer up-to-date, visit one of the following sites.
The Microsoft Security and Protection site has the latest advice on using firewalls, Windows updates and anti-virus software. This site also features warnings about any new viruses and any additional steps you need to take to protect, or fix, your computer.
If you are on a Mac, check out the Apple security site for information on system and security updates.
Please note that Virgin Media are not liable for any charges incurred by rogue diallers.
