Computer Crimes

Today, I write about "Computer Crimes".

 Nowadays, there are various computer crimes.

I cannot introduce all of them so I take up some themes.

The first theme is “Computer virus”. Computer virus is one of the most known computer problem. Computer virus defines a kind of the illegal program which brings damage to a computer. There are a number of kind of computer virus such as “Trojan horse”, “Warm virus” and “Logic bomb”, you computer may have damaged. The early virus which only reproduces its copy, is only infected between computers through a floppy disk etc., sometimes displays a message, and surprises a user was harmless. But After the second half of the 1980s, a virus evolved gradually and began to become the cause of bringing about realistic damage. The kind of computer virus is continuing increasing day by day and it is said that tens of thousands of sorts of computer viruses exist. On the other hand, development of the "vaccine" which remove a virus has also been furthered in parallel with evolution of a virus. In order to prevent infection of computer virus, introduction of anti-virus software is effective and the easiest. You should keep anti-virus software which install in your computer the newest thing because anti-virus software is often updated.

The next theme is “Online fraud”. Nowadays, the Internet spreads rapidly and is used all over the world. The Internet is very convenient but it is often abused. An online fraud is one of them. One of the online fraud has one-click fraud. One-click fraud means that if you click URL sent by email once, you are made to contract without your agreement. You may be blackmailed if you do not pay a charge. You may pay because you do not want it to be known. However, since the contract which has not obtained both consent is invalid, regardless of a click-through count at all, the contract is invalid. It can be considered that it is fraud to charge after they know to consent to the failure of a contract, so you do not have to pay.

The last theme is “Penny auction”. Penny auction is a new Internet problem. It is an Internet auction of the form that a commission is needed for every bid at each time. Although the upset price and contract price on a display are a small amount compared with the usual auction, the commission at the time of a bid becomes a large amount of money in many cases. Moreover, even when you are not able to make a successful bid as a result, it will be necessary to pay a commission. The number of consultation increased rapidly, so Consumer Affairs Agency urged the nudge to use in December, 2010. Penny auction site closing succeeded one another from the autumn of 2010 from the influence of a report of the trouble about such a penny auction.
