In a world wide web there is a set of the websites which can be threat for your computer. Also resources which are engaged in different types of fraud, distribution of pornographic materials or promotion of terrorism, etc. belong to such websites. Such websites are blacklisted so-called.
The majority of the websites of the black list pose in themselves the explicit or hidden threat for your computer by entering of a dangerous virus there or are way for hackers to fill up the purse or to receive from you passwords of systems where you are registered. Very often they mask under popular social networks where for registration you need to perform operation on replenishment of the unknown account. Or, finding the social network searching, you can come across information that your account is frozen (is blocked). And further at you ask to transfer money for an unblocking. It is necessary to remember that such companies as VKontakte, "Schoolmates" and others do not collect means for activation of your profile.
Such type of Internet fraud is called a phishing. Vendors of web browsers already agreed about ways of fight against such websites. In many browsers the system which informs the user on threat and closes access to the website joins, or warns about danger and suggests to select – to follow the link or not. By results of polls first place is won by "Firefox". It was recognized as more effective in detection of phishing sites.
However there are services which look as the normal websites, but pursue the different aim. Some suggest to download video content for the decent sum which should be transferred to the given bill. On the one hand it looks as online store, with another urges on young users to spend means of the parents.
Besides there is a huge number of the websites of the extremist and religious orientation urging to join the ranks. Here too the security system will not work, and everything will depend only on your consciousness.
It is necessary to mention also the websites which offer different types of earnings. Their feature is that from you can ask money for registration. Or you at small monetary expenses, after success and replenishment of a virtual wallet you will not be able just to receive the earned means. They either will pass to the owner, or will remain in a virtual mode. It is possible to carry also different Internet casinos to such websites.
