U disk virus exists in the U disk, you can spread to the computer, the poisoning of the computer can also be transmitted to the U disk U disk, so that the computer and u disk cross spread. The general virus will also detect the inserted U disk, and its implementation of infection operation, leading to the birth of a new virus U disk. This is especially true in schools and companies. Under normal circumstances, U disk virus disguised as a system file automatically hidden, or disguised as other files exist, but also hidden in the system folder, the use of Window vulnerabilities, hidden folders. The virus program can not blatantly appear, usb virus remover are generally clever in U disk.
The following summarizes some of the ways for reference only: 1) hidden as a system file. General system files are invisible, so this achieved a hidden effect. But this is also relatively elementary. Now the virus will not generally use this approach. 2) disguised as other documents. Because most people do not show the suffix of the file, or the file name is too long to see the suffix, some of the virus programs change their icon to the icon of another file, causing the user to open it by mistake. 3) hidden in the system folder. Although it feels the same way as the first one, it is not. System folders here are often deceptive, such as the folder name is the name of the recycle bin. 4) some of the virus hidden folder named runauto ..., this folder can not be opened, the system prompts that there is no path. In fact, the real name of this folder usb virus scanner is runauto ... \. 5) generate the corresponding folder icon virus file (folder imitator) or shortcut (Storm One). 6) other new u disk virus: For example, the 2010 mask ken exe disk virus, when the virus can be through the u disk (mp3, mobile phone memory card, mobile hard disk) spread of infection, we collectively referred to as u disk virus. When you put the U disk infected with this virus into the computer, once you open the U disk, the computer will be infected with the virus. Similarly, when you plug a USB flash drive without a virus into a USB flash drive, the USB flash drive immediately becomes infected. |
