@carsten ibsen: add a Disk Imaging Backup solution (Macrium Reflect Free or AOMEI Backuper, are free and reliable).
Also, to run Bitdefender Total Security+Zemana Anti-Malware Premium+Heimdal Pro+Voodoo-Shield Pro is overkill as real-time protection, I think Your don't need neither ZAM nor VoodooShield running alongside BTS. You may keep ZAM for on demands scans.
In field Virus and Malware Removal Tools: You may delete BTS, as You are using it as real-time solution, here You may add Norton Power Eraser.
I also believe that you should make a backup and not for a malware attack, because I believe that a malware against your computer is like trying to repel a nuclear attack with two stones, but there can always be a hardware failure, by a power failure or anything else outside your defense.
Scheduling the backup task while at those times when you are not using the computer can be the difference between a good day and a bad one
I would also suggest a good free backup solution. As also mentioned above either Macrium Reflect or Aomei Backupper both have a good free and reliable version for you.
