best antivirus software for windows

Antivirus software is a computer-based program used to detect, prevent, and remove malware that has infected your device. They are very essential to protect your data and privacy from getting corrupted or stolen.

Whether it’s your Windows PC, Mac, tablet, laptop, or anything, all devices are continuously exposed to malware attacks. Hence, having a stealthy antivirus program will not risk malware attacks. Therefore, antivirus programs are available for a wide range of operating systems, including Windows, iOS, Android, and even Linux.

How Does Malware Attack Your Device?

Viruses lurk everywhere; even if you take precautions when performing internet searches, you could find a virus that costs you a lot of time and money. Hackers constantly develop new forms of software for any purpose like:

  • Steal your personal information from computer files
  • Steal bank information or account login info
  • Pop up ransomware threats to get money from you
  • Turn your device into a ‘bot’ to perform email spamming.

Some risks are more serious than others. On the other hand, Viruses nearly always consume CPU, memory, and other system resources, reducing your productivity and jeopardizing your privacy.

Do you need antivirus software?

With preloaded virus scanners and protection tools, many users think about whether they should go for a third-party antivirus program or not. Some experts argue that you don’t need to have antivirus until you follow a safe browsing habit.

But, in one line, the answer is, “YES, YOU DEFINITELY NEED AN ANTIVIRUS SOFTWARE!”


Nowadays, hackers keep working on different ways to create and improvise malware. There are different types of viruses that do not look malicious at all. They do not even steal your data or do any financial harm; they execute other activities. 

You never know when a piece of adware will start stealing your data or giving hackers access to your device. You cannot tell when a secure website becomes harmful, no matter how cautious you are while browsing.

These are some of the reasons why you should safeguard your software against viruses.

  • Protect your files, personal information, etc.
  • Setting parental controls so that your children or any others person cannot access something harmful.
  • Keeps you from infecting others while you are communicating.
  • Blocks untrustworthy websites and warns you before you enter the browser.
  • Adware makes your PC real slow, so antivirus gets rid of adware and makes your PC fast.
