I use already for decades Kaspersky and was / am always very satisfied with the program. The databases are updated daily and it recognizes many extremely harmful software. The installation runs smoothly, and the program is very comprehensive and easy to use. The price of 30 euros per year license is in my eyes really very moderate for the performance. Sure, there are other programs that are better. However, for the "average consumer / user" This program is perfectly adequate and keeps the PC from malicious software clean.
Conclusion: Good Antivirus Program, which no large Hardwareresoucen eats, keeps your computer clean and always up to date. Highly recommended.
