In order to protect your computer from viruses you should have multiple levels of security. The more updated you maintain your computer software and the more layers of security you add to your device, the easier it will be for you to maintain it virus-free. New viruses and malware are released on a daily basis on the Internet. Hence you should always stay diligent and well-informed about the latest cyber threats in order to protect your system from potential vulnerabilities.
Keep your Operating System and Security Software Updated:
One of the important things to do in order to protect your system from viruses is updating your operating system with the latest security patches. If you are a Windows user, you should install the latest security updates from Microsoft and, similarly, if you are a Mac user, you can enable automatic updates from Apple. This could help in thwartingany security loopholes that were present in an outdated version of your OS. These security patches will contain hot fixes to security bugs and will help you in eliminating any vulnerabilitythat might be present in your computer. You should not only update your operating system but also security software installed in your machine with latest virus signatures and patches. Also you should keep all the software applications such as web browsers, media players and utilities updated so that there are no security loopholes in your system which can be exploited by hackers or malware. You should especially keep your web browsers updated with latest available versions in order to browse securely.
Install Reliable and Powerful Antivirus Softwareon your Computer:
The first thing you should do in order to protect your computer from viruses is installing powerful and reliable antivirus software. There are plenty of free antivirus programs available on the internet, but not all of them are 100% effective in protecting your system from viruses. You should choose the best antivirus software that will perform periodic scans of all the files present in your system. It should be able to detect any recent virus signatures and malware present in e-mail attachments. Bitdefender is the world’s leading antivirus software which offers 100% protection against all possible cyber-threats without causing a heavy impact on your system’s performance. You should also keep your antivirus updated with latest virus signatures on regular basis.
Avoid opening e-mail Attachments without scanning them:
In order to keep your Computer free from viruses, you should exercise great care when you open attachments from unsolicited e-mails. Ensure that your e-mail application is not configured in such a way that it automatically downloads the attachment files. E-mails containing malicious code or viruses could masquerade as important messages coming from known sources. Hence you should not be fooled just by looking at the email contents. You should always perform a detailed scan of the email attachments using powerful antivirus software before opening or downloading it. Most of recent viruses spread through e-mail attachments and they get automatically copied to your machine when you open the attachment. You should only trust emails from legitimate sources and whose email address can be digitally authorized. For your safety, you should trust only emails which are digitally signed and should never open attachments from sources you don’t recognize.
Avoid Downloading Unrecognized Software such as Freeware from Internet:
One of the easiest ways for viruses to enter your computer is through software applications that you download from internet. You should always avoid installing software in your desktop that you download from unreliable sources such as promotional websites or internet forums. Most of the freeware applications, games and screensavers that you download from internet can contain malware or viruses that will get launched once you execute those applications. If you really need to download any application from internet, make sure you thoroughly scan it using antivirus software. You should avoid installing free games/apps from internet since they are most common source for viruses and malware.
Scan Floppies/CD/DVD/USB Media before copying files to your Computer:
Whenever you copy files from a CD or USB flash drive to your computer, scan those files using antivirus software. There are many instances in which viruses could spread through files copied from external hard drives or USB flash drives. Even a known colleague or friend could accidentally pass along a virus or malware to your computer by sharing files through floppies/CD or USB devices. Always avoid booting your device from external hard-disk or flash drive since they can contain boot viruses which can entirely harm your computer.
