The Best Practices for Computer Security

Computer security protects against unauthorized access, including hackers attempting to penetrate computer defenses via the Internet. New viruses and malware are created each day, but some basic security features keep machines safe from data theft.

Antivirus Software

Antivirus software protects against maliciously coded programs. Viruses are often packaged with some programs that look innocent, and run in the background of the computer. Antivirus software prevents the malicious code from loading on computers; clean machines that already have viruses; and run scans that quarantine infected files. This security measure protects users from data loss, and prevents password and identity theft.

Firewall Software

Firewalls differ from antivirus programs because they simply block incoming and outgoing communication with the Internet, protecting computers from spyware. Firewall applications are sometimes included in purchased antivirus programs or installed on routers purchased for home and office networks. Firewall software alerts the user that an application is attempting to access the Internet, which helps identify spyware applications. Spyware often uploads passwords and data to hackers who use the information to steal identities. Firewalls protect personal and company data.


Passwords protect computer files.

With networks becoming commonplace for homes and offices, passwords are options on operating systems such as Windows, Linux and Unix. Users are urged to apply a strong password to log into the machine. The password prevents unauthorized access to hard drive files, either in person or via the local network or the Internet. Passwords should contain letters and numbers, and at least one special character for more security. Network administrators can create password rules so users are forced to enter strong passwords.

How to Repair PC Security After a Virus Attack ?

A virus attack can be very devastating to your computer if it is not caught quickly. Computer Viruses change many different settings on your computer so that the virus can hide information and download some additional files to your system. Once the virus has been disabled and deleted, the settings need to be restored to their original configuration to get the computer running normally again. Repairing your PC’s security after a virus attack needs to be a top priority to prevent further virus attack and infection.

Follow the Instructions:

Step1: Open your antivirus software and update it by clicking on the "Update" button on the start page.

Step2. Disconnect your computer from the Internet once the update is completed. You don't want your computer to be infected with another virus through your modem while your security settings are still compromised.

Step3. Restart your computer and hold down F6 to activate Safe Mode. Scan the system again in Safe Mode. Restoring security settings will do no good if there is still a virus lurking on your system. Delete any hazardous files that are found.

Step4. Restart your computer normally and access your security settings through the Control Panel in the Start menu. Click on the Security Center and click on the Firewall to make sure it is enabled.

Step5. Reconnect your system to the Internet and update your Internet browser to make sure you have the most recent browser that has closed previous security breaches.
