     A new problem has appeared in the world of technology- the mobile phone viruses. The first virus
called "Skulls" and "Dust", was discovered in July, 2004. Compared to computer viruses, these were
harmless, but proved that a virus could be spread across a mobile network.
     But as mobile phone technology moves forward, so do the viruses and the people who create them.
Now many people use "pocket computers" such as PDAs and "smart-phones" which can receive multimedia
messages in different forms like photos, videos, and music, and the most recent virus, "Cabir", is spread by
opening these kinds of multimedia messages. This virus gets into the mobile phone or PDA and then makes
it stop working. In only six months the virus has spread across almost 20 countries across the world-that
shows that it could easily get into millions of phones and PDAs.
     There are some viruses inside illegal (非法的) copies of games. These viruses take personal information
that is stored on someone's phone, and use it to make money for the people who sent the virus. Sometimes
the viruses have a programme that makes expensive phone calls to high cost numbers. The result is a very
high phone bill for the victim (受害者).
     In answer to this new threat (威胁), many new models of mobile phones and PDAs are now appearing
in stores with anti-virus software on them, just like computers.
