BD Episode 2: The Return of the Forced Scans

This is a bit of a joke right? I just moved to bitdefender and am seriously regretting doing so. This should not be hard to diagnose and fix for the technical team.

Hello all! So I appear to be affected by this issue as well. Searched for similar occurrences and found this thread. In my case, it definitely appears to be some sort of startup scan that is hitting all of my drives after every boot. I have about 30 TB of local storage in my rig across four hard drives; one SSD and three mechanical. The drives get scanned in order as listed in task manager on the performance tab. Unfortunately, it is taking around 30 minutes to an hour to get through them all after logging in (30 TB is quite a lot). I have tried turning the Early Boot Scan option off in Antivirus > Advanced settings, but the scan is still occurring. It's the bdservicehost > Bitdefender Virus Shield process that is causing the spiked disk activity - I can tell since it's still top of the processes list sorted by Disk utilization after the early post-login processes have settled down.

Would love to know how I can prevent this from occurring, and I am happy to help with any troubleshooting steps I can perform. Please let me know.

Thanks!

Are these problems related?

Thanks, do Your words help me back buying my phone and 💻 and data, nope , it's a discrimination between the freedom of you and us, because I'm a poor Iranian who you believe that people are not law for life and by political perspective .Kaspersky and Bitdefender are responsible for this situation and are now because live in Iran. it's a good reason for telling me your laws. I'm just a health promotion officer and by the way you told me what do better, sit and cry

>>How can I see if I have received the update?

I see a minor update in the build number: Update 26.0.25.84 --> 26.0.25.86

Also make sure you have got the latest signature updates.

For me, boot-up is back to normal. But keep in mind: It's just a rollback, not yet a fix.

Thanks to Ironbuket and Camarie for getting this issue resolved.

Camarie. I have two questions:

If the fix is to respect user exclusions, why have they been ignored up to now? It doesn't make sense to me that Bitdefender has exclusion settings but the program ignores them? Clearly I'm not understanding something here?

Is the cause the same as the cause last time this happened? See the previous thread, or a different cause this time?

Thanks for the information Camarie. It is interesting hearing how things work behind the scenes. It also gives confidence when a company replies to issues.

Just out of curiosity how does an anti-virus company deal with the life cycle of threats?

Take log4j as an example. When it was discovered it was a huge threat. Large actions needed to be taken immediately. A lot of pressure to put log4j as top priority. But as time passes this will become less urgent. Say a year from now, 2 years, 5 years. Anti-virus should still be able to pick up log4j, but computers owners who are not dealing with the vulnerability it becomes more and more the owner's fault for not updating and dealing with the known weakness. It feels like as time passes that AV products should move new threats up the priority list. When log5j and log8j threats turn up you guys will be prioritising those. Does log4j get pushed down the priority list as time moves on? Will the AV products becomes les aggressive in CPU and Disk access as the threat becomes older?

The hard coding of the log4j optimization seems counter to this. When log4j is 5 years old will your corporate customers till be burning CPU and Disk access treating it as a top priority pre-optimization by scanning in advance for log4j? Will the pre-optimization be removed and log4j treated as a normal priority virus in 2 or 4 years from now?

I am not asking out of frustration, or trying to be difficult. You have fully dealt with problem that made me frustrated and I am grateful to you for that. I'm considering waiting a month or two just to be safe then re-installing Bitdefender. I am more asking the question above out of my own curiosity. Not often do we get to engage with AV professionals, and learning a little bit about the process is interesting.

@Nunzio d'Abbruzzo

With the less powerful PC's would it help by disabling some of the "optional" high resource programs from startup in MSConfig or Task Manager?

I don't see it as a laughing matter, I see it as both disappointing and frustrating

Bitdefender is not ideal for an old system like yours. It's not going to be any lighter. Bitdefender is very fast on a decent system with SSD. Your system config is simply not strong enough for BD to perform properly without having the impact that you're having.

There are one or two other free AV that might do a better job on your PC. Since it's a Bitdefender forum and not related to the topic, I'm not mentioning the names here.

@HomoSapiens

Ok, I'm back to report something, after reinstalling it again today, I saw that the same thing happened again, so I had to turn off the HDD's hard disks from Win11, to prevent it from scanning one after the other, but then, on the main disk C: SSD NVME, it kept scanning it, for no reason at startup.

I have found that the product installed updates every time I reinstalled it, and today it notified me of a product update just after, having finished the annoying service task.

Apparently, after updating the antivirus, I restarted and this did not happen again. But, my question is, when you download from your account, and bitdefender central, when assigning a device, and download the installer.

Shouldn't the product come with all the updated libraries and files? to prevent this from happening? I mean if the fix is applied or has been applied in my case, after installing an update, when checking for updates.

I am sorry if I speak from a lack of knowledge, or the correct function of how this works, but as I said, I noticed that every time I completely uninstalled the antivirus and re-downloaded it and ran the tests, these updates were installed later, in my case, the fix seems to have been applied, after 2-3 update notifications, one of which was the last one and was for the product in general.

Guys, I believe we've proven transparency is one of the fundaments of this community. Feel free to express your opinions, even if that means suggesting a competitor. We aim to be better, not hide stuff under the rug.

@Ironbuket well, gifs are part of the forum culture and this is a forum, after all. I'm sorry if this offended you in any way. We have a different approach here and you may find gifs and memes occasionally, because we are not the black-suit-and-tie kind of admins around here. We are real people with a good sense of humor and lots of appreciation for the members of this community and starting from the very beginning, we wanted to do something that stands apart from other forums in this niche and build a welcoming and inclusive virtual environment, where people can express themselves freely and get closer to our teams. Because in the technological era we live in nowadays, the human touch is paramount to a real and satisfying customer experience.. Surely, there are areas of improvement and if we make sure to listen, not only hear, we can put the feedback to good use and improve.

Of course, there are certain limits and moderation is part of our job. But if someone posts a picture, or a gif that may put a smile on someone's face in times of trouble, I see nothing wrong with that and I encourage it. You have noticed that we do keep things professional and tidy around here, but that doesn't mean we cannot have a good time on these pages, even if we are confrunted with an issue, or frustrated because of something that doesn't work as expected, having a nice atmosphere and meaningful, quality conversations from which all parties can benefit, will help clear the air and also difuse unpleasant situations.

In regards to the competition, we respect all cybersecurity, IT solutions out there and I believe we are not racing or competing against each other, but share a common goal: to protect people's sensitive and personal information, defend against malicious threats and become the best version of ourselves. I don't know how many of you know this, but apart from the home and enterprise solutions, our detection technologies are also being licensed to about 30 percent of our competitors in the anti-virus space. So, you can mention anyone you wish, as long as it's in a decent form of expression.

Here you will find more transparency than anywhere else, this I can assure you.

Cheers!
