File Extension QIT

The file extension QIT is associated with a Trojan Horse, which is a malicious program that disguises itself as a legitimate application on your PC. A Trojan Horse is created by savvy programmers with malicious intent for the purpose of taking control of a PC or a group of infected PCs which is known as a bot.

The Trojan Horse computer virus gets its name from the Trojan War in Greek mythology. As the story is told, the people of Troy were presented with a wooden horse presented by the Greeks which had Greek warriors hidden inside. Overnight, the warriors were released from the wooden horse to take over the city of Troy.

The file extension QIT is specifically associated with Backdoor.QIT which enters a PC without the knowledge of the user. The Backdoor.QIT Trojan Horse is programmed to enter a backdoor on your PC which is an undetected vulnerable area in the operating system. A backdoor not only allows the hacker to access your PC, it also provides them with the means to return and enter the system even if you change password access.

The file extension QIT is a malicious file type that contains executable files which are launched once the Trojan Horse enters your PC. The executable contains malicious code that performs a variety of criminal functions such as logging your keystrokes (keylogging) in an effort to steal your passwords, mailing spam to your contact list, launching fake antivirus programs that trick you into revealing your credit card information, and other malicious acts.

How to Open QIT Files

If you are trying to determine how to open the file extension QIT, a strong word of advice is not to open the file under any circumstances. Although you may have an antivirus and anti-malware program installed, a Trojan Horse can sometimes manage to slip by PC protection applications.

If you have received an email attachment that contains the file extension QIT, delete the file without opening it to prevent your PC from being infected. To play it safe, perform a complete scan of your PC after receiving the attachment to double check for other existing malware.

If you discover a file that contains the QIT extension in the Documents folder or other location on your PC, delete the file as soon as you discover it. Follow up by performing a complete scan of your PC using your antivirus and anti-malware PC protection applications.

It is also important to mention that some Trojan Horse viruses can replicate even after you have deleted the file from your system. For this reason, it is important to run the PC protection program you use after restarting your PC. If you are tech savvy and know how to work with the registry, you can disable a self-replicating Trojan Horse by finding the files in the registry and changing the file extension to OLD and changing the binary to 0. This will disable the Trojan Horse altogether and prevent it from restarting each time you boot up your PC. After you restart your PC, you can delete the modified files from the registry and perform another scan with your PC protection program.
