New viruses
Anti-virus programs are not always effective against new viruses, even those that use non-signature-based methods that should detect new viruses. The reason for this is that the virus designers test their new viruses on the major anti-virus applications to make sure that they are not detected before releasing them into the wild.
Some new viruses, particularly ransomware, use polymorphic code to avoid detection by virus scanners. Jerome Segura, a security analyst with ParetoLogic, explained:
“ | It's something that they miss a lot of the time because this type of [ransomware virus] comes from sites that use a polymorphism, which means they basically randomize the file they send you and it gets by well-known antivirus products very easily. I've seen people firsthand getting infected, having all the pop-ups and yet they have antivirus software running and it's not detecting anything. It actually can be pretty hard to get rid of, as well, and you're never really sure if it's really gone. When we see something like that usually we advise to reinstall the operating system or reinstall backups. | ” |
A proof of concept virus has used the Graphics Processing Unit (GPU) to avoid detection from anti-virus software. The potential success of this involves bypassing the CPU in order to make it much harder for security researchers to analyse the inner workings of such malware.
Explanation of what is a computer virus, you can give a few. The most simple - domestic explanation for Housewives who never in his life of the computer is not seen, but knows that He is, and that It found Viruses. Such an explanation is given quite easily, which cannot be said about the second explanation, designed for a specialist in the field of software. To me, it is not possible to give an exact definition of a computer virus and to make a clear distinction between programs on the principle of «the virus is not a virus».
On Friday, on may 13, 1988, several firms and universities in several countries of the world met with the virus of «Jerusalem» (Вирус) - on this day the virus destroyed the files when you run them. This is, perhaps, one of the first MS-DOS virus, which became a reason of this pandemic messages on infected computers came from Europe, America and the Middle East. Name, by the way, the virus got on the place of one of the incidents - University in Jerusalem.
Together with several other viruses («Cascade», «Stoned», «Vienna»), the virus «Jerusalem» has spread to thousands of computers without being seen - antivirus programs have not been distributed in that time as widely as it is today, many users and even the professionals have not yet believed in the existence of computer viruses. It is indicative that in the same year a computer guru and man-legend Peter Norton spoke against the existence of viruses. He announced them non-existent myth and compared with tales about the crocodiles living in the sewers of new York. The incident, however, did not prevent the firm Symantec after a while start your own project antivirus - Norton Anti-Virus
I Love YOU (вирус)
This virus was notable for the fact that he was cleverly coined. The user that the mail came the message «I LOVE YOU» with your file attached, started to download it, as it was very similar to the love letter. In the end, the file used a script that send a lot of email, traffic and even after just delete important files on your PC. The results shocked the all - 10% of all computers were infected and brought a net loss of $5.5 billion. The virus «I LOVE YOU», probably, it is listed as number one on the caused damage.
Рисуем кактусы акварелью
Распускающиеся бумажные цветы на воде
ГЛАВА ТРЕТЬЯ, в которой Пух и Пятачок отправились на охоту и чуть-чуть не поймали Буку
Домик зимней ночью
Центральная часть Млечного пути приоткрывает свои тайны
