Be safe from computer virus

Computer virus are such type of the programs that can be transmitted from one computer to another and cause the adverse effects to computer. These viruses can not only corrupt the files and data but also can damage the whole hard disk drive. In the past time these virus are transmitted from the email but nowadays pen drive or also known as the flash drive are the means to transmit the computer virus.

Some of the symptoms that are seen when the computer is affected by the virus are:

1. The computer performs in slow than normal.
2. The system gets crash and restart time to time.
3. The application programs in the computer don't work properly.
4. The menus are in unordered manner.
5. The anti virus of the computer gets disabled.
6. New folders are created automatically.
7. Programs are lost from the hard disk.

Many of the computer users use windows operating system. Windows is vulnerable to the virus. But there is the full protection from the virus in the unix and linux operating system and also from the hacking problem.

While surfing the internet there is the maximum chance to get affected from the virus if you don't use the anti virus and firewall. The default browser of the windows called internet explorer is taken as the unsafe software in terms of the protection. Inside of this you can use other browsers like firefox, chrome etc. But the most safe way is the use of the latest and updated antivirus. The antivirus must be updated time to time in order to protect from the new virus in the internet world. Similarly downloading and running the unwanted softwares from internet may also cause the transmission of virus. The transmission of the virus by the use of the pen drive is due to the autoplay feature in computer. The autoplay makes the programs run itself whenver CD-ROM or the pendrive are inserted. In this way as you use the pendrive the autoplay makes the virus run automatically and spread in the system. Hence to protect the computer from this virus you should disable the autoplay feature in the computer. For the xp users these are the steps to disable the autoplay:

• Open the run by clicking "run" in start menu.
• Type gpedit.msc and enter.
• Click computer configuration and open anministrative template.
• Then click system and turn off the autoplay by double clicking.

Doing this the virus are not spread only by inserting the pendrive as the autoplay is disabled. If you are using other's computer then keep pressing shift button before inserting pendrive upto sometime you inserted it. This will make the autoplay disabled for a while. And open the pendrive with the folder explorer rather than double clicking.

If you are the internet user then you must use the firewall in order to protect your computer from the unauthorised access and hacking. Firewall is the software that can protect your computer from the access of the unauthorised users in the network. This also checks the each and every messages and data that pass through the network and access or block them as necessary. Firewall can also be used in the safe browsing of the websites. There are many types of the firewall like free firewall, software firewall, hardware firewall, desktop firewall etc. The desktop firewall protects from the remote login in the personal computers.
