Viruses trick money from Windows users without copyright

Recently, a dangerous program appeared on the computer with the ability to hijack the system and give fake notifications to trick users.

When the virus is activated, users will not be able to control their computer, and the screen will warn: " Windows license has been locked. Reinstalling the system may cause personal data to be lost. ".

Next, the virus example fixes the problem by calling Microsoft switchboard to receive the Windows activation code in detail. With the current use of pirated software, many people mistakenly believe that this is Microsoft's Windows copyright activation service and call the instructions.

Fake warning of the virus.

Mr. Vu Ngoc Son, Director of Development Research Division of Bkav, said: " Hackers hit the psychology of most unauthorized Windows users and made them nervous after receiving alerts. Every time Calling will cost 0.7 USD and Bkav's test shows that it takes a few calls to contact the switchboard, of course, those calls lose money and that is the hacker scenario . "

Bkav also found a secret code built right in the virus without having to call. Users experiencing this situation may use the code 1351236 to temporarily regain control of the computer.

In addition, many people have been unable to connect to the network after killing the Ndisvan virus, currently infecting about 39,000 computers in Vietnam.

When intruding, Ndisvan becomes ingrained into the system and becomes part of the computer's network connection chain. The usual way to kill antivirus software is to delete the file containing the virus, but that means deleting a link in the network connection component of the infected computer. In this case, the user must reinstall the operating system. Therefore, they should choose anti-virus software equipped with virus removal technology from the system, not merely deleting files containing viruses.
