I have just reinstalled BitDefender and all of the old problems have returned:
Slow CPU
High Usage of RAM
Panic crashing post iMac going into sleep mode.
I have followed all the advice mentioned below.
Which anti virus package would the community suggest I use - BitDefender feels more like a virus than an application that keeps my iMac safe.
iMac 27″, macOS 10.12
If you check around this forum there a couple of things which are stated repeatedly: You should never, ever install any antivirus app in a Mac. It will definitely slow down the computer and will often cause other serious problems. (Such as you have experienced.) No antivirus app is ever needed. Macs have their own built-in protection. Also, the operating system is write protected, so no changes to it can be made by any source other than Apple. Go to BitDefender's web site and download their uninstaller app. Use it to remove all the various bits of the app which are scattered throughout your computer. Then rest assured and don't concern yourself about viruses.
