You may be wondering what exactly is Autorun.inf and how did it get inside your drives. The reality is that you are dealing with a classical computer virus in the form of a worm. This thing is absolutely impossible to remove manually unless you know the right way to handle it and it will also spread between infected drives. In this manner it is able to infect computers that are not connected to a network.
Autorun.inf is characteristic for its ability to lock people from accessing their drive’s content by locking the drive into an auto run loop menu. At the same time the virus may seek connection to the internet in order to upload various interesting information it may recover from the infected files – such as accounts, passwords and more. Sometimes Autorun.inf may work in conjunction with various spyware or keylogger programs in order to make them impossible to remove and to assist them with siphoning your data back towards their creator.
How was my PC infected with Autorun.inf?
There are multiple ways of how this may have occurred. We‘ll try to listed the most common methods, but this list is by no means exhaustive and you can use your imagination to fill in the blanks depending on your particular circumstance.
Because Autorun.info is actually a computer virus it is able to replicate and install itself in all types of drives – HDD, SSD, flash drives and other. This means that whenever a clean drives come in contact with an infected one the virus will spread and infect them both. It is entirely possible that one of your own mobile USB Sticks came into contact with an infected computer and then spread into your own. The same applies to any other drive connected via the USB interface to your PC – that of a Friend, colleague or neighbor.
This is why plugging random devices into your own computer is a bad idea, although sometimes this remains unavoidable. For these situations a good anti-virus program is invaluable, because it will both scan the drive for viruses and block any such from installing into the computer parent.
It is also entirely possible that this PC was originally infected from a file obtained online. The usual carriers are
- Attachments in malicious emails
- Warez copies of pirated software T
- Files downloaded from torrents and online storage sites
- Malicious links spammed in forums, chat boards and other media
If you know for certain that a computer or device is infected you have to make sure to isolate the problem only to the computer/device. Try to limit its networking sharing permissions and absolutely never plug in any other media, or you risk it becoming infected as well.
Typically the virus installer will pose to be something else entirely or will be imbedded into a modified installer for a program. For this reason it is usually a bad idea to download executable files from such unsafe locations, especially when it comes to illegal software. Most torrent networks lack any security measures at all and thousands of people may become infected from a single virus infected file, especially when it is related to a popular program for download.
