I Bidefender for 2 years on my PC that seemed especially by slow elsewhere on the Internet (I had never been able to analyze the hard drive because it took longer than 24 hours), I had given up analysis by PC antivirus. By Kaspersky, my PC to the Internet has become much faster and I was able to analyze all of my hard drive in less than 45 minutes (no virus found so Bidefender had done this work I admit), I recommend Kaspersy that Norton had also replaced my PC a few years ago; Norton I had nothing but trouble (I left there 10 years).
