Strengthen the defense of your computerStrengthen the defense of your computer

How do you strengthen the defense of your computer? You should have instant Firewalls. "Firewall" will separate the internal network and the Internet. The firewall carries out some filtering when two networks communicate. It lets the data that you allow to enter your network, and also block the data that you disallow from your network. It can prevent malwares from changing, copying, or destroying your material. You must keep your firewall update to ensure it work perfectly.

Then, you should prevent virus from entering your computer. You should install the Anti-virus software and start the real-time monitoring process and keep the software and the virus definition file up-to-date by setting the update process in daily mode. You should scan your computer every week with latest updated anti-virus. You should scan your USB pen drive before you plug into your computer as it is one of the fastest ways a virus infecting and spreading in your computer and to other computers.

Finally, you should guard against Spyware. Spyware is a program that is installed without the user authorization. It can obtain the information and send to a third party. Spyware can automatically attach in software, executable image and break into the user computer. They are used to track the computer usage information, record the keyboard hits, or take a screen capture. To get rid from spyware, you should raise the security level of your browser, install software to guard against from spyware and verify with the official website about the software you would like to install. You may install Sandboxie to protect your computer from the attack of spywares.
