[Fixed] Network Traffic Causes Bitdefender To Use Excessive Cpu

Wow, feels a little bit good to just hear of others having this issue. It has been driving me and my wife CRAZY on our two laptops. It all started around a month or so. I'm trying the "disable port scan blocking" right now. My CPU would never go to 100%, but it might as well had with all the stuttering and audio cracking issues it would display. Even the mouse would lag and jerk.

Hopefully BD will fix very soon. I've used them for several years and this is the first issue with them, so I'm willing to cut them a little slack this one time.

If you say that the previous version of BD worked fine, why not install that version? Always the newer version has some problems. This is because they try to keep up but not always and for everyone this would work. If you are sys admin like you claim why you are so puzzled about this common situation..

Why shouldn't I be puzzled with a common situation that is affecting my computer? Why should I have to downgrade to a previous version, because of 1 simple bug, that can be easily fixed. Now that I finally received a response from Bitdefender and am working with them, maybe this will get resolved. This is how it works with software. If no one reports it and no one has the time to deal with trying to fix a bug, it will stay like that. Bugs are meant to be fixed.

Downgrading to a previous version to resolve my problem isn't a solution to take, that's like downgrading to a O/S no longer supported.

please don't forget to share the fix for that proplem with us thank you .

Still no fix..

After sending them logs and them giving me a scenario of what to try to fix it (basically do a repair of TS 2016), which did nothing. They told me this: "Please be kind and send me a new support tool log and after I receive it I will send your case to our superior technical department ."

Like seriously, they $uck a$$ at customer service and support. I told them to visit this thread on their own forum. I'm about to contact sales to have my 2 years I just stacked on revoked for a refund and just deal with the problem for the remainder of time I had left of 4 months and switch.

Yeah, I'm looking at Kaspersky and Avast! Will weigh the alternatives over the weekend.

I was looking to use Kaspersky as well as an alternative

but after looking to that video

I changed my mind

You think they don't know there are some problems and now because you were so brave to report, everything will be ok? They receive performance reports from every bd pc. That download problem is old as a monk. Maybe you should try BD Box

Please just leave this thread, you are giving no help what-so-ever. You are basically copy and pasting information that can be seen by just doing a Google search or looking at this forum alone. If the download problem is "old as a monk". How come you haven't reported the issue yourself? Do you not care about being provided the best software as humanly possible? Or would you rather just invest in software where it is never fixed or updated? REAL companies listen to their customer's problems. Maybe you have never dealt with a company like that before. Also, if you are going to give stupid sarcastic responses and troll this thread, maybe you should at least try learning good English.

On mine, it's looking possible that the 'Block port scans in the network' being enabled is causing the problem. Leaving firewall enabled, but disabling that single option seems to have it working fine again. Can't say I feel to comfortable about having to disable a pretty significant security option to be able to have my internet connection run at any decent speed.

Nor should you have to disable the product. I'm sure that they will implement a fix if enough people report this issue.

Yeah, agreed, but during my ongoing email conversation with them about this problem, this is what they suggested about having that option disabled

"Configuring the settings in this way will not leave your PC unprotected and you are completely protected by the core Bitdefender modules."

Completely protected? so what am I with the option enabled then? I might be reading more into it than there is, but that suggests to me they consider that fixed.

I'm having this problem as well. I first thought it was the Wifi driver from Intel that's causing the problem... Turning off port scanning is definitely helping at the moment, but it really shouldn't be a long term solution... Will email BitDefender and hopefully they'll fix it soon.

In desperation, I even tried a clean install (formating and reinstalling everything) but nothing changed...

The only solution up to now is to desactivate the port scanning in the firewall option. It immediately resolves the problem.

But I'm not fan of this solution.

All i wanted to say is from my 5 years bd user experience i thought it might help. Had same download issue and every time i was eager to install the latest bd version. But now after all what i've experienced i came to the conclusion that is not a very good move to uninstall which is a bad idea in general no matter what av is used because pc remains unprotected for a short period of time during the change plus the compatibility issue might occur. I m not denying your opinion but i just wanted to help and come up with alternative solutions. That BD box idea would make a huge difference between a normal bd av installed on pc because will work as av + ips. You could request a change of the product in a your favor. Sorry for any inconvenience i caused to you or other members but that was not my intention. Have a great day and a virus free pc

Hello all,

A case was created on our internal testing platform to further investigate the issue you report.

We will keep you updated with any progress we make.

please I need a fix also for that proplem

I contacted bitsy@bitdefender.com still no answer

when scan ssl is turned on twitch show black screen

and the only fix for that is to turn scan ssl off

even with a new windows 10 install same proplem

I have bitdefender total security 2016 .

I've just submitted more logs on my own support ticket, although reading through them, it's just a load of PINGS and Tracerts with basic network config included, nothing that could help them with their own code...

I notified them about this issue in mid-March and have yet to have ANY helpful suggestions from their tech support. When people on this forum figured out that it was the "block port scans" option messing it up, they said I should just do that and that it wouldn't compromise my security. Total BS. Plus, why did it take their customers figuring it out on a forum? They couldn't figure out what was causing it and issue a patch? Most of their email responses are simply copy/paste or automated. They've asked three times for a support tool log which I supplied in the second (of a now super long) support email chain. Shameful.

The unchecking of the block port scans does not resolve the issue. See above.

I've been having the same issue here for about 1 maybe 1,5 months on both my desktop and my laptop. Issues appeared, coincidental or not, after replacing my router. Used to have a Huawei HG 655 (so nothing fancy) and I replaced it with an Archer C2 (still nothing fancy but a big step up). Issues that were described in this thread by others started immediately after that. Only thing that actually fixes it is disabling "block port scans in the network".

Weird thing is I have some friends using Bitdefender IS 2016 with some chea.p routers (something similar to what i used to have, the HG 655) and they don't have these issues. Could it be coincidence or is there something different in these more expensive routers that conflicts with Bitdefender and the port scan option?

Still no response. So, I've contacted sales to revoke my 2 licenses purchased for 2 more years and asked for a refund. Let's see how long this takes.

a new update that required s restart released today

I got it and it asked me to restart

Updated, tested, still a problem.

It looks like a moderator has merged two forum topics, one about high CPU usage and one about throttling started by AcePuppy ( see the old version here )which is why this topic suddenly has alot more replies than I remember and why the conversation seems a bit disjointed.

It would appear they were meant to be separate since the issue in the original excessive CPU topic could be fixed by turning off the "block port scans" option in the firewall, whereas that didn't work based on replies in the thread started by AcePuppy.

Hello all,

Sorry to hear that the high CPU usage persists with the latest build version 20.0.27.1467 released yesterday.

This issue was escalated to our developers for further investigation. I will update you on this once I receive more details from my colleagues or to let you know about the fix delivered via automatic update of Bitdefender.

Thank you for your support and patience.

Hello, I see my thread was merged from the Protection forum. I don't believe this should have been done. Our issue in that thread was bandwidth throttling with the firewall being on as you can see from my replies and others. Our issue was not a high CPU problem. Please understand that this is 2 separate problems.

Still waiting Bitdefender. STILL WAITINGGGGGGGGGGGG

Can say this still is not fixed although it appears to happen less often. I haven't yet found at trigger for it.

This time I was downloading a .exe and sending a different file from my computer to another via Microsoft Remote Desktop.

The main symptom was lagging and jerky mouse on the desktop.

The low part in the middle of the graph is when i toggled the "Block port scans in the network" option off and then on again

Windows Performance Analyzer

.

I'll keep an eye out and try to find a reproduction case.

As the name implies the situation has been sent to development, when we will have a update on the matter, the thread will be updated.

Rest assured the situation is not forgotten and it is being worked on. The developers are being poked and prodded for a answer.

@AcePuppy please take the time to read the forum rules, spam is not tolerated consider yourself warned.

If you wish to bump a thread do it constructively, add something that might assist in resolving the issue not complicate it.

Hi Spikeles,

Please upload the graph to www.wetransfer.com and post the download link, I will send it to the devs. Thank you

@Spikeles I have downloaded the file and sent it to our devs, thank you for your assistance.
