Why autorun program becomes virus.
Hi! Dear,
Viruses are for disturbing you and a virus needs no permission.Then how can a virus disturb you?It happens on how they write the virus.They write in some such of a kind of code that it starts to work automatically and spreads it out automatically and create a same file like itself at many places in the computer and attach with exe files of your software and if you install any type of antivirus and when you scan your computer then that exe file removes from your computer because it is effected and now your software is useless.
OK.
Why autorun program becomes virus.
When USB flash drives became popular, so are the autorun viruses that became rampant because of this type of device. Most autorun viruses are Trojans and its primary objective when they enter the system is to install itself in all of the hard drives and most especially in Windows registry. When it installs itself in the hard drive, its main target is the System Volume Information folder. This folder can be found in all of the drives and is located in the root of every drive. This is a hidden system folder and is not normally visible in Windows Explorer. To make this directory visible, you need to enable the Show hidden files and folders option in the Folder Options and uncheck Hide protected operating system files.
The System Volume Information folder contains all the restore properties of that specific drive and if a Trojan worm, like the autorun virus, infects this, the whole drive is affected. Autorun virus is very alarming because all USB flash drives that will be inserted in the computer will automatically be infected and when that flash drive is inserted on another computer with a weak antivirus, it will eventually pass the infection on to that machine. And the cycle continues.
