freeze upon startup — Expert Community https://community.bitdefender.com/en/ Thu, 03 Oct 2024 22:02:47 +0000 en freeze upon startup — Expert Community Random hangs for small percent of mac clients https://community.bitdefender.com/en/discussion/96721/random-hangs-for-small-percent-of-mac-clients Thu, 03 Aug 2023 21:40:01 +0000 Install and Updates adidasnmotion 96721@/en/discussions We have a strange issue with BitDefender on about 10% of the maOS clients we have it installed on. Our macOS clients are Intel computers running 12.6.8. We started having some of our macOS clients randomly hang from time. On a couple of machines we started experiencing an issue where the computer eventually became unusable. It would hang at login and either never become responsive or it would automatically reboot itself. We even wiped the drive and started over on one of the affected computers and discovered that the hang at login wouldn't occur until we installed BitDefender again. Uninstalling Bitdefender the problem would go away. After further testing we figured out that the problem returns only if we reinstall BitDefender with the "Network Protection" features turned on.

We've now implemented that change on all the problem machines and that seems to have resolved the issue. Is there a known issue that might cause this? Is there a way to fix this? We'd like to protect all the macOS computers the same way if possible.

Bitdefender had not worked so well for me lately on this machine, and I just don't know what is the problem. About 4 or days ago, Bitdefender was once again became unreponsive and I restart my computer. However, once it boot_s into the desktop, my computer was blue-screened. I thought it might be Bitdefender. I ran a bug check analysis and here is what I got.

oddly enough, the bugcheck analysis did not point to Bitdefender as a culprit. However, when I did some search around, some sources say that error IRQL_GT_ZERO_AT_SYSTEM_SERVICE (4a) is frequently associated with Bitdefender. I am really confused. I already open a support ticket 4 or 5 days ago with no reply to my problem. My ticket number is:  2016101410170003 . Right now, I already uninstall Bitdefender and running Microsoft Security Essentials and Malwarebytes free as temporary means to stay safe. So far, everything seems fine. No more BSOD. Anyone know about this particular problem? I would not want to run MSE for too long since I am not sure about its detection engine. Thank you

 

Products: Bitdefender Antivirus Plus 2016.

Operating OS: Windows 7 x64 Ultimate

Other security software running in conjunction with Bitdefender at the time of install: None

*edit*:  Could the moderator please move my thread into General Section? I think I click on the wrong subsection and ended up in installation and activation, but I think this is more of a General Problem.
