Bitdefender Internet Security 2018 preventing system boot

After Bitdefender Internet Security 2018 recently updated itself, it required a reboot to apply the changes. However, the reboot could not complete and a Windows startup trouble shooter began running but was unable to find or fix the problem. Only after I rebooted in Safe Mode and uninstalled Bitdefender (BD) was I able to reboot normally. I reinstalled BD, and everything seemed fine. But the very next reboot failed and I went through the same process again - reboot in Safe Mode, uninstall BD, reboot normally, reinstall BD.

I have sent logs and files to BD Support for analysis and hopefully a fix. Still waiting.

Has anyone else experienced this issue?

I am running Win7 Home 64 bit on a Dell Studio XPS7100 with an AMD Phenom II X6 1045T 2.7GHz chip with 6 GB memory.

sorry to hear about it mate. Its actually an issue that affected 100's of clients - after an update that was released, here's an article about it - Bitdefender Ironically Stopped Working on Safer Internet Day

I'd set my updates to auto-update at 12hours interval, so I missed this bug thankfully - I'm on Internet Security 2018 as well, infact I bought the pack just 1 day before this mishap happened.

Have you tried applying the latest updates after you'd reinstalled it ? BD mentioned, then reverted back to an older db to prevent users from facing this issue, when they issued an fresh update it was released with in 30-60 mins if I recall correctly - they stated the reason for this mess is because of an incomplete update download at user's end from their server.

why don't you try installing Comodo Cloud AV (free version) or any other AV for a few days & later try to reinstall BD & check if you're still facing the issue ? Its not a fix but at least you can have something to work around

Once I get a good reboot and reinstall BD, I have no problems. I do have a BD update pending that wants me to restart, but I am leery of letting it loose. I never had any BD error messages like the ones in the article you provided, just a Windows start up error message and a series of messages from a Windows startup repair program that could not resolve the problem on its own. I am hoping the BD CS team can use the logs/files I sent to get me fixed. since my issue appears to be somewhat different. Thank you again for your willingness to share important information on the BD problems.

Now a month later I have received confirmation from BD tech support that my problem is related to their new firewall. The only way I can reboot with BD active is to manually edit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and change the ignis value to "4". That prevents the BD firewall from loading, and my reboot proceeds normally. Of course I have to turn on the Windows firewall. BD has advised they are testing my issue in their labs and will follow up with a solution. It has taken over a month and 40+ email/chat exchanges to get to this point. Very disappointed in their responsiveness.
