When Bitdefender 2015 detects an infection, it will take automatic action for the detected malware.
Some malware will have to be cleaned when Windows starts and for this situation, we recommend you to run a System scan on that computer.
In order to do that please first update Bitdefender to be sure you have the latest virus signatures: open the main interface using the Bitdefender icon from your desktop. Click the Update button from the main Bitdefender interface.
After the update is complete, please run a System Scan: at the Protection panel, go to the Antivirus module where you should have the System Scan. At the end of the scan, a scan log will be generated; all detected and resolved items will be stored in it. If you want to manually remove an infected file, you can follow the steps from our article.
If infected files are still found on the system (and they haven’t been resolved by the Bitdefender scan) please generate a scan log and send it to the Technical Support Team via the opened ticket you have with us. You can see here in our article how to generate a scan log.
