The best world-wide reviewed antivirus software are Kaspersky Anti-Virus and Bitdefender Antivirus Plus. The battle between them begins firstly with the price comparison. After checking different offers from multiple sellers, the winner is Bitdefender Antivirus Plus with the price of $29.95.


The installation process is very similar between them, the only difference that can be found is in the interface design, which clearly cannot be the same. To download the software you must make the payment online using a credit card, there you will be given the option to choose for automatic renewal, meaning that they will charge your credit automatically when your subscription comes to an end. Some users might see this option as annoying, but this is not a problem because it can be disabled after you install the software. The estimated installation process for both Kaspersky and Bitdefender is around 5-6 minutes.

Extra features

Both Kaspersky and Bitdefender havev a “game mode” that can be use for entertainement. You can play video games, watch movies, tv-shows and the software will not stop your activity.

One of the differences between the antivirus programs is that Bitdefender provides the buyer with a file “shredder”. The “shredder” helps the user delete documents of sensitive material, and it also has a password manager for complex passwords. Kaspersky also has this feature, but only for a more expensive packet.

Malware detection

Both the products had their malware detection testes by two product-testing labs. The AV-TEST lab in Germany and AV-Comparatives located in Austria. The products were tested against a large number of malware, and in the end they measured how many of the malware they caught and how many managed to breach their security.

Bitdefender performed without any problems, managing to have a 100 percent detection rate against the tests performed in January and February 2016 on Windows 7. Kaspersky got a detection rate of 99 percent, managing to get three perfect marks.

On windows 8.1 Bitdefender managed again to get a perfect score after three tries, and Kaspersky got a two perfect scores out of three security tests. Kasperksy did not receive any false positive, while on the other hand Bitdefender had one false positive.

Security features

Both of them have a big number of security features, but the most relevant one is the dedicated defense against ransomware. Both Kaspersky Anti-Virus and Bitdefender Antivirus Plus have this security measure, but one of them is stronger.

The software have high defenses against ransomware that locks your screen. When hackers use ransomware, they block your screen with a splash-screen and ask for money to be sent to a Bitcoin or Paypal account. Here Bitdefender shines because it locks down files that are chosen by the user to be under safety, so the user doesn’t lose his files.


Bitdefender Antivirus Plus is clearly the best decision here. It detected more malware than Kaspersky Anti-Virus and it also did not impact the computers performance too much. And the price difference is pretty big, considering you can pay $29.99 for one year of Bitdefender Antivirus Plus and $34.99 for a year of Kaspersky Anti-Virus.
