For now I would like to get rid of (if installed?) drivers of DB3 and possible infected files you have moved.
Programs that claim to update your drivers install either the wrong or corrupted drivers.
If you have installed any driver with Driver Booster 3, please remove them as it may cause trouble.
Please run a threat scan with Malwarebytes*, a full scan with your AV, scan your system with Adwcleaner, Kaspersky TTDSKiller, ESET Online Scanner and SuperAntiSpyware
*(Uncheck trial version in the installation process)
It is best to start troubleshooting with an installation clean of malware.
