"Phishing" is a kind of fraud attempting to get our personal information such as passwords and credit card dates. Its way to trick us is that:
1, Send a e-mail to us
A swindler sends e-mails that is fairly similar to these of true bank, credit company, and shopping site to us. By reading these, we would belive these contents.
2, Induce us to browse a false site which is very like to that of bank, credit company, and shopping site.
The e-mails say that we have to access site of bank and credit card company and tell them our personal information. Because we believe the e-mails, we are induced to browse not a true site but a fake site, thinking the site is genuin site.
3, Have us tell them our personal information
After inducing us, they have let us input personal information and they acquire that, leading to a bad scheme.
After getting our personal information, a swindler makes bad use of it and get a lot of money, while we suffer from money problems caused by them.
To let us not to be deceived, we should renew a version of browser that we are now using. Old version of it don't find the site that e-mail show a false one while an up-to-date browsers often can find that and warn us strongly. Also, we can find the sites that e-mails show are false one by confirming a key mark: SSL mark, that tell us that sites that have SSL mark may be true site.
But now, deceivers have devised a new method that we cannot deal with. Therefore, We have to keep paying attention to Phising.

File sharing software is a software that enable us to share files that someone has. For example, "Winny" is a kind of it. It was used to share data in a company, group, and so on. It has two dangerous points. The one is infringement of copyright. By using file sharing software, people share works that has high values without paying money. This has a big damage on writers. And the other is leakage of information. When you use file sharing soft and get virus, your file will be shared by a lot of people. Therefore, it is possible that your personal information is made bad use of and you may suffer from problems of money, privacy.
To prevent data from being shared, we should not use file sharing softwware, although it sometimes very useful.
