@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.
Thanks for sharing
