It’s not safe to browse the Internet without having an antivirus program installed on your computer. Many websites are infected with viruses and malware, which affect the performance of your device, or even help hackers to gain control of it and steal your data.

This is why it’s indicated to use an efficient antivirus software, to protect your computer against cyber attacks. Two of the best products are Bitdefender and Kaspersky, and below we’ll compare their prices, interface, level of protection, performance and features.


At this moment, if you want to buy the Bitdefender Internet Security 2015 from the official website, you will pay $59.95 for 1 computer, one year, $39.95 for three computers (a discount of $40), $119.95 for up to five computers, while price for up to ten computers is $209.95. If you have a computer and need the license for two years, you’ll pay $89.95, while the price for three years is $129.95.

Kaspersky has price of $39.95 for one PC, 1 year, while for two years, the license costs $54.95. For three computers, one year, this antivirus program costs $75.95, while for three years, the price climbs up to $105.95.


Both programs have modern interfaces and they’re easy to use. Their features are intuitive, but there are also hidden menus for advanced users. Bitdefender has some modules which categorize different tools and the users are able to access common features without looking for them through menu items. Kaspersky has a similar user interface, but it’s more visually appealing.


Many independent researchers who installed Kaspersky noticed that this program can detect up to 80 percent of known viruses, which is a mediocre score, because other products can detect over 90 percent of known viruses. Bitdefender falls into the second category, having a score above 90 percent. This program firstly checks new files in the existing virus database, then sandboxes potential threats and doesn’t take action until it’s sure that the files are dangerous, and finally, it checks every process to detect malicious activities.
