I've been using Bitdefender free version for some time and it has 5 processes which run pretty high putting Disk to 100% very often or Memory and CPU to high levels even without browsing or anything. Long story short it uses more resources than other AV. Maybe it's only me. I'm on W10 pro Intel i3 HP 4GB RAM 3.6 GHz desktop.Well, I decided based on what the article said to try BitDefender (I'm a huge fan of set and forget) instead of Kaspersky. However, I've also been a user of the paid version of Malwarebytes for a long time (first for work, then for personal use) and BitDefender refuses to finish installing unless I first completely uninstall Malwarebytes, which it identifies as ''another antivirus program'. I'll try doing that and then seeing if I can reinstall Malwarebytes afterwards, but from the virulence of the popups I'm getting from BitDefender, I have my doubts as to the success of that endeavor.
