Tech Guide - Securing your system from viruses

A computer virus is a malware that, when executed, replicates by reproducing itself or infecting other programs by modifying them. Infecting computer programs can include as well, data files, or the boot sector of the hard drive. When this replication succeeds, the affected areas are then said to be "infected". 

Definition of computer virus is quite easy to understand but it's not the same with viruses. Once your system(computer /laptop/ mobile), it make all possible harm to your system and data. 


If you are wondering how to avoid viruses and keep your system virus free. Here are few things to follow for a virus-free system :) 





Install an antivirus program –
You should install the antivirus program, the very first thing after installing the OS. It’s very important in the new emerging networking trend where we are in touch base with each other via social media. Data transfer has been a daily task these days that even school going kids are hands on with. Hence it's necessary that we keep on running the scanning software in the background while working with our system and always scan the external device like pan drive before connecting with the system.

Don't open email attachments unless you're expecting them –
Whenever you receive any email from an unknown person always make a thumb rule that you delete that. If you think that you should check it before deletion, you should scan it properly. One simple step can save your PC and rest of the data residing there.

Keep your computer updated –
You should check for the patches/ update in every month released by Microsoft or other vendors. Most of the time when we install any program then the wizard shows an option “check for auto update”, you can check that or later check the update manually as well. Mostly when you are connected via internet, the program itself pop up the window. OS patches are available every second Tuesday of every month, you can keep you system up-to-date by using these options.

Use a firewall
Windows Firewall can help restricting unnecessary access to your system. You can restrict specific type of access (Inbound or Outbound) based on your requirement. It also blocks viruses, worms, and hackers from attempting to download potentially harmful programs to your computer. If you are an expert you can restrict specific type of ports by making rules inside the firewall.

Use your browser's privacy settings. 
If you mistype a URL and the website is fake then the websites might use your private information. It is important to prevent fraud and identity theft, especially if you are working on a public PC or from cyber café that you delete all your personal information before leaving the system. If you're using Internet Explorer or any other browser, then always ensure that you are deleting the temporary and cookies files before leaving the system.

Use a pop-up blocker with your browser. 
Pop-up windows are small browser windows that appear on top of the website you're viewing. Although most are created by advertisers, they can also contain malicious or unsafe code. A pop-up blocker can prevent some or all of these windows from appearing. It can easily be achieved from the Internet Explorer or related browser’s settings.

Keep your system safe and virus free 😊
