Full system scan caused hard crash

Hi there
Like the thread title says: I attempted to run a full system scan on my PC on 01/May/2021 using Bitdefender Internet Security. After running for a few minutes the scan "froze" and seemingly caused a hard crash on the system:

- The mouse cursor remained visible and mobile, but the Bitdefender interface would not respond to attempts to close it.
- The date-time display in the task bar stopped working (it showed 23:18 when the scan became stuck, and was still showing 23:18 ten minutes later).
- The computer would not respond to ctrl-alt-del, alt-tab, etc.
- All other elements of the Windows UI were unresponsive.
- The computer's fans were running at full speed, suggesting 100% CPU usage.
- After waiting for 20 minutes and observing no change in Bitdefender, a hard reset (holding the power button to force shut-down) was the only way to regain control of the PC.

Bitdefender was fully up-to-date and had run one previous system scan successfully. Windows 10 had been fully updated prior to the installation of Bitdefender. I was not running any other security software in parallel with Bitdefender.

Is this a known issue with current versions of Bitdefender Internet Security? I switched to Bitdefender after being badly let down by Avast's software and support, and it's very worrying that this has happened only two weeks into a two year licence.

    There is currently no issue pertaining to bitdefender product. The scan may sometime use more resources if there are other background services running. Since bitdefender has to compete with the sharing of the resources with the other background processes, and if your system requirements are not met with minimal system requirements needed to run bitdefender product, it may end up in hanging of the system.

    Kindly collect bitdefener logs (https://www.bitdefender.com/consumer/support/answer/8919/) & drop an email to bitdefener support at [email protected] with your query. Also attach the logs with the same email.

    Regards

    You should note that it is better to have a new cpu like core i3 8100 or i5 6100 or i3 6100or better for example or ryzen cpus.(I mean your cpus have at least 4 core and 3.2ghz for good working when using bitdefender).
    I mean that using old cpus like intel pentium (r) core duo 2.7 ghz or 3 ghz not recommend for bitdefender and for bitdefender it is necessary to run on ssd to don't slowdown your pc.
    I don't say you can't use it on hdd but it is very ideal to use it on ssd (because forexample its startup is take much time even on ssd and in normal using may lead to hanging or some slowdowns for your system if you use hdd).
    And for ram it is good to have at least 6 or 8 gigabyte or ram.
    and I should note that I don't have your problem when I select my hdd partitions to scan but I think bitdefender have some problems on scanning the hdd drives because it have make some bad sounds and high sounds of hdd that I think it is not happened on other antivirus product like kaspersky and eset.
    One of the way they can fix this problem is that they use smart scan method that forexample eset use that and it detect all of the virus if its database has them.(I mean this method works greatly and bitdefender can use that scan way.)
