On 12/13/13 I logged a support ticket with Bitdefender regarding the program consistently crashing every time Game Mode was enabled. In addition to that bug, the constant hard drive access by Bitdefender's Autoscan feature was unlike any I've ever seen from an anti-virus. I let the program download it's first virus definition database and ran a full system scan, which took roughly 5 hours to complete. I had assumed that this would lessen the amount of on-access scanning in the future as most antiviruses these days have a "scan only when changed" sort of feature to keep from unnecessarily scanning the same file twice. According to the built-in Windows Resource Monitor the Bitdefender process was still accessing the same files after the scan. Throughout the next week I was having trouble with Bitdefender automatically updating. It would warn me that the virus database is out of date. I would open the security center, update the program, and all would be fine. The next day I would experience the exact same issue. In addition to all of this my computer has BSOD'd several times since I've installed the program, which is very unlike my usually smoothly running computer. I mentioned this to Bitdefender support as well. On 12/18/13 I was contacted by Bitdefender and requested to generate a support log and attach it to my next email. I provided them with the log the next day. On 12/21/13 I received another reply from Bitdefender asking that I uninstall Malwarebytes Anti-Malware from my computer, as that is what is likely causing the majority of my issues. I was about to explain that the program is on-demand only, and does not run in the background. However I gave them the benefit of the doubt and uninstalled. The issues persisted. I continued to find little quirks and issues with the program the week after the last email. The security center would alert me to “serious issues affecting the security of your pc” and upon opening the security center I would find absolutely nothing wrong. All of this combined with the performance and auditory annoyance of the scanner constantly running the the background was enough for me to email Bitdefender and ask for a refund of my purchase. I sent the email on 12/23/13 and have not received another reply since. I understand that the holidays may be causing a delay in our exchanges, however I’m having serious doubts about the program itself now. Has anyone else had similar experiences with BD? I'm not sure where to go from here.
