Bitdefender’s product suites for Windows are more extensive than Kaspersky’s. Each suite comes with multiple scanning options that will ensure your device’s protection from malware. These include a quick scan to find the most suspect locations, as as a full scan on the entire computer. Both suites come with a firewall that monitors the devices that are part of your home network and blocks unauthorised connections.
Both tools do a good job in preventing phishing attacks by blocking fake websites that impersonate legitimate ones, and stopping ransomware from altering files or holding them hostage. Kaspersky provides a tool that can reverse the ransomware attack and recover files, and it has a feature to automatically identify and stop known threats when they are discovered. It scored highly in AV Test’s antiphishing tests as well as the antiransomware test.
In our tests of system performance, Bitdefender was lighter on resources than Kaspersky and a little faster in establishing and running. The labs also examined the suite’s ability to identify malware on their own. The results were mixed. both suites performed well in catching most of the malware that we tested with (which requires advanced detection capabilities) however, they struggled to identify widespread infections that other software already knows about and can thwart by using known signatures or patterns.
Bitdefender is the winner in the customer support fight, as it provides more support channels that are easier to use user interface than Kaspersky. It offers 24/7 phone, email and live chat support, along with a knowledge base and remote support for premium users. It also includes a password manager and a free VPN, and other security tools in its higher-priced plans.
