How to remove Virus

If you use computer through internet, web browsing , or downloading softwares and other data, you will know about computer virus or other malware. These are those malicious programs that once they infect your computer. Malware is programming or files that are developed for the purpose of doing harm. Thus, malware includes computer virus, worms, Trojan horses, spyware, hijackers, and certain type of adware.

Different types of Virus:

Adware - A program that randomly displays  pop-up ads on your computer or displays advertisements.

Backdoor - A program that allows a remote user to execute commands and tasks on your computer without your permission. These types of programs are typically used to launch attacks on other computers, distribute copyrighted software or media, or hack other computers.

Hijackers - A program that attempts to hijack certain Internet functions like redirecting your start page to the hijacker’s own start page. Restoring your system gets rid of the Hijacker virus without making you  modify the registry.

Spyware - This program is a type of malware that can be installed on computers, and which collects small pieces of information about users without their knowledge. Typically, spyware is secretly installed on the user’s personal computer. Sometimes, however, spywares such as keyloggers are installed by the owner of a shared, corporate, or public computer on purpose in order to secretly monitor other users.

Trojan - A program that has been designed to appear innocent but has been intentionally designed to cause some malicious activity or to provide a backdoor to your system. This virus disguises itself as a particular application or toolbar you would want to download. Once you click on the download option, it will instead download the Trojan on your system. This virus can then send out important information from your computer to the hacker.

Virus - A program that when run, has the ability to self-replicate by infecting other programs and files on your computer. These programs can have many effects ranging from wiping your hard drive, displaying a joke in a small box, or doing nothing at all except to replicate itself.

Worm - This program has the ability to spread to other computers on its own using either mass-mailing techniques to email addresses found on your computer or by using the Internet to infect a remote computer using known security holes.

Use an anti-virus software to remove the infections:

Make sure you are using an anti-virus program and that the anti-virus program is updated to use the latest definitions. If you do not currently have an anti-virus installed, you can select Nod32 or Kaspersky and use it to scan and clean your computer.
