If you use a dial-up modem to access the Internet and see a costly international call on your phone bill that you don't remember making, you may have been the victim of an international dialing scam.
Here's how it works: Some websites encourage computer users to download software in order to view certain material. The software you download may disconnect your computer modem, then reconnect it using an international long distance number. The result: your modem may actually be placing calls to distant countries with the charges showing up on your bill.
Download with caution
You should never download programs from the internet without reading the disclosures. Some websites, advertised as "free and uncensored," may include disclaimers that often appear in a pop-up window revealing information on possible charges or rerouting of the website. It is important that you read the disclaimer to learn what charges will be assessed before you click a box agreeing to terms and conditions.
If a disclaimer says something like, "you will be disconnected from your local Internet access number and reconnected to an international location," and you agree to download anyway, you may receive a phone bill with high international toll charges. You also may be billed from a non-telecommunications company that provides a billing service to the website.
Also, some pop-up ads may install spyware-type programs that disconnect and reroute your modem, even if you do not give your permission.
Tips to reduce risk
- Ask your service provider for an international block on your computer line.
- Consider disabling your modem, if you have broadband internet access.
- Take advantage of firewalls, virus protection and anti-spyware software, and ensure you have downloaded the latest updates for the operating system and browsers you use.
