backdoor virus is a malicious code which, by exploiting system flaws and vulnerabilities, is used to facilitate remote unauthorized access to a computer system or program. Like all malicious code, it works in the background oblivious to the victim. This access gives it total freedom to conduct malicious activities on the system. The system is now vulnerable to illicit file copying, modification, data stealing, and additional malicious injections.

If your computer has the backdoor virus, then the hackers can have a clear view on all your personal information such as online transactions password, your credit card pin code and your bank locker number. These viruses serve as a tool to break your security walls.

These viruses may be transferred to your system when you visit any unsecured websites. Initially they will pretend to be normal software. But later when they come in contact with the required information, they will change to a backdoor virus. They will be saved as any other normal application until they get their required information from the host system. After a point they will serve as a remote system which allows information transmission.

How do you protect yourself from backdoor attacks?

*   Never click on any screen pop ups

*   Do not run connect to internet without updated antivirus installed in your system

*   Never get into any unsecured website

*   Never click any suspicious websites.

*   Do not change the spelling of any website address

Have the above security tips in mind when operating your computer systems. Report any cybercrime incident/activity
