After the recent ransomware attacks, the first thing that the PC users are looking for before buying a security application is Ransomware protection. A ransomware is a malicious program that locks down your computer.

WannaCry, the dreaded ransomware that affected 200K computers this year barred Windows users from accessing their accounts. It replaced the Windows lock screen/welcome screen with a message to transfer a random bitcoin amount to a bitcoin address.

To regain access to their accounts, companies and individuals transferred the requested amount to the bitcoin address.

What should you do when a Ransomware infects your computer?

Install Linux OS, copy important nonexecutable files to a flash drive or Linux partition, format the NTFS or FAT partitions and re-install the Windows OS. You can also clean the PC with an emergency rescue disk.

Free vs paid: Which antivirus should you use?

Windows 8+ OS ships with the Windows Defender AV program. It also includes a powerful firewall tool and a SmartScreen utility that displays a warning message when you try to open an executable file downloaded from the web.

WD does a decent job of protecting the PC, but Microsoft doesn’t provide regular virus definition for this program. This is the reason why Windows OS users use a third-party security software.

Top security companies have launched free antivirus programs for Windows. The programs have limited features but they get regular updates. Unfortunately, the top-rated free AV applications don’t protect your PC from ransomware or malware. They don’t allow users to create a rescue disk.

To protect the computer from all types of threats, you must use a good internet security application. The most popular security applications for the Windows OS are Kaspersky, Avast, and BitDefender.

Below, we’ve compared the features and the performance of the three programs.

Bitdefender vs Kaspersky vs Avast

Kaspersky, BitDefender, and Avast have launched 3 security products for the home users – a standalone antivirus program, Internet security, and Total Security.

The 1st product from the 3 firms is cheap and it offers basic features. A standalone AV software is a great asset for computers without an internet connection.

Internet Security suite is a must-have software for Windows users who spend most of their time on the web browsing social networking sites, shopping, or accessing bank accounts. It prevents users from opening phishing and malicious URLs. It monitors email ports and blocks phishing and junk emails.

The program ships with a WiFi analyzer utility which displays a warning message when you try to connect your device to an insecure WiFi hotspot. It also blocks unauthorized users from accessing the webcam. Internet security suites include a Firewall utility that filters harmful data packets. You can block certain Windows apps from accessing internet by creating a firewall rule.

Apart from the regular virus and privacy protection, the Total/Complete Security suites of Avast, Bitdefender, and Kaspersky provide extra security features.

Kaspersky Total Security ships with a password manager and file encryption tool. It also provides parental control settings which you can configure to prevent kids from browsing inappropriate websites.

Avast Premier software is a good alternative to Kaspersky Tsec. It includes a file shredder and app updater tool. It prevents DNS hijacking attacks and sends suspicious file to an Avast server for analysis.

BitDefender Total Security packs the following features:

  • Multilayer ransomware protection.
  • Parental advisory, Autopilot mode.
  • Photon module.

AV-Test, the independent IT security firm benchmarks antivirus applications and publishes the results on its website. The firm tests programs on Windows XP, Vista, 7, 8, 8.1 and Windows 10 OS running computers.

Which is the best security software among the 3?

I’ve used Kaspersky, Avast and Bitdefender Internet security on my laptop. These 3 programs run in the background without degrading the computer’s performance. They are easy to use and have a powerful antivirus engine.

Kaspersky’s security products are cheaper than that of BitDefender and Avast. If you are searching for a cheap AV or IS application with excellent ratings, buy Kaspersky. Avast and BitDefender are good alternatives to KS.

BD has an autopilot mode feature which handles computer security issues on its own. It analyzes the computer hardware and changes program settings automatically. BD’s ratings and reviews on software download sites aren’t great.

Avast is an impressive program with a good AV test score and excellent ratings. You won’t be disappointed if you buy an Avast security product.
