[solved] Computer Slowsdown With Bitdefender

sonoransunburst

I’m experiencing an issue with BitDefender that has been occurring since I purchased and installed it (digital copy) a few weeks ago. My computer has slowed way down since installing the product, and my internet access is also affected. When I click on any icon or start any program there is often a 15-30 delay before the program actually opens. When I open Chrome it takes the 15-30 seconds, plus whatever webpage it’s trying to load will either time out or take a really long time to load. Once whatever program is started it seems to run OK, with the occasional hiccup. While these delays are occurring, there aren’t any other obvious things running, and there is no disk access happening. It’s like everything is just hanging in limbo until something times out and it goes on its merry way.

If I uninstall BitDefender the problem disappears. It reappears when I reinstall the product. I tried this twice.

My system is running Windows 8 64-bit on 16GB or RAM, 4.8ghz I7 processor.

I downloaded and ran the Bitdefender support tool that I saw in another thread while I was researching the problem. I tried to attach it to this post, but it said I'm "not permitted to upload this type of file."

Any help you can offer is greatly appreciated.

Thanks.

Intrusion detection system is found in firewall settings.

Keep Intrusion detection system setting in Permissive mode.

See if this helps.

Also make sure you have downloaded bitdefender from trusted location. Click on link below to get the official download link.

I think I have this same issue as well, checked my firewall settings and they are already as instructed.

I only started noticing this issue as soon as I uninstalled the old version and installed the new one.

Hi,

I didn't have this problem with the last bitdefender but I do with the latest version.

It seems after Bitdefender has run its idle scan or whatever it does when it is idle, the computer becomes incredibly unresponsive, taking 30 seconds plus to open a program or go to a webpage etc, my system runs off an SSD so I know that isn't causing the slowdown, the problem only started since installing the latest Bitdefender.

I have a similar problem.

Same problem here, since the 17.15.0.682 update after an autoscan my computer becomes unresponsive as does the Bitdefender interface, I have to restart my computer to fix this, I'm also using a system installed on a SSD.

Yes thats pretty much the same as me, getting fed up with it to be honest, only a restart seems to sort it and even then it takes ages to restart!

It is fairly annoying, especially since I've only just recently purchased a licence for Bitdefender and now it's having this problem.

Do you think it could have something to do with the Firewall/IDS? I had problems yesterday with windows and web pages freezing as mentioned in the below post. I'm using the New version AV+ (on this partition) and had been running a 3rd party firewall which included HIPS. Since I uninstalled that firewall, everything has been responding normally. So I wonder if that could be something to consider, especially with the Photon technology running in the background: http://www.hotforsecurity.com/blog/bitdefe...hoton-6477.html

The Photon technology gradually “discovers” the currently installed applications on the user’s computer and molds on every PC configuration individually by learning which processes need monitoring and which ones do not. The result is a lower number of files that need constant supervision and less system resource spent on watching perfectly safe applications, which allows the scanner to fully concentrate resources on potentially malicious files.

Maybe in self trouble shooting, try disabling the Firewall (if concerned, during that time, turn on Windows firewall) IDS, and maybe even then if needed, AVC, and see if we come up with a common result?

Also, what would be helpful to each other, as well as to BD support who do read these threads, is what version of BD you are using, AV+, IS, TS, and what OS you're running. In this case, AV+, on Windows 8 Pro, 64-bit.

-------------------

-------------------

... other problems are random freezes that unfreeze after some time. Also the firewall keeps asking several times for the same program even thought i have the application (browser) open and doing normal browsing. Old paranoid was better.. I love being asked to allow programs but not again again until i reset rules...

Latest TS Bitdefender and Windows 7 Ultimate.

Broken Hope

I'm using AV+ on Windows 8 64 bit and no firewall software.

I'm using AV+ on Windows 8 64 bit and no firewall software.

That's good to know, as we both have the same set up, that it may not be a firewall/IDS issue? I'll keep using this partition, and see if it changes, and gets slow or unresponsive.

Honestly it only started when they did a program update a few days ago, it's something Bitdefender have done IMO.

Yes it's something I have only noticed recently.

I have 64 bit Windows 8 & Bitdefender Total Security(Latest version)

It would be nice if we had the option of rolling back a build update that may have caused issues, separate build, virus def. update tab options.

I have noticed the same thing. ###### annoying having to restart your computer everyday.

Yes it is getting annoying as you know when it happens as everything stops responding. Hopefully a quick fix is on its way!

This problem occurs whenever there are events showing in the widget. These events are always cookies that the Autoscan has detected and deleted. Page loading slows to a crawl and computer must be restarted to fix the problem. Annoying.

Hmm thats interesting, I don't use the widget however? But even when restarting, thats taking forever as well. Bit of shame there doesn't seem to be any offical response on the problem

ragbuster

Seems to occur on my machine when the computer attempts it scan after being switched on in the morning, probably after it has retrieved its daily definition updates.

I don't think the widget has anything to do with it. I was just implying that the problem only seems to occur when Autoscan has taken action on something.

Hi,

I have the same problem. I am sure it depends onnautoscan, because in laptop mode there seems to be no problem but I will analyze today.

I have already opened a ticket.

I am having a similar issue along with other problems. I am running on windows 7 ultimate 64 bit, 8gb of ram, AMD FX 8350 cpu, SSD and an nvidia 780 gtx. Adding up to the problem i have several other but similar to this one i have random disconnects from games and communication programs like TS3.

The funny thing is that i posted 6 days ago a problem about autopilot and haven't got an answer from the support team and this topic seems unanswered too.

Jonj1611

Yes its definitely autoscan related. I dread leaving my computer in case it starts and I can't find where to turn it off either.

Happens during the 2nd autoscan for me. Opened a support call about it

Turn off auto scan, you give the autoscan off and will not turn on

Hello all,

Thank you for reporting this situation.

We need to identify first which Bitdefender module is causing this issue. In order to do this please follow these steps:

1. Open the Bitdefender window either from the Desktop shortcut or by clicking on the Windows Start button -> All Programs -> Bitdefender -> Bitdefender Antivirus Plus or Internet Security or Total Security;

Note: for Bitdefender Antivirus Plus, please skip the 3rd and 7th step.

2. From Antivirus turn Autoscan OFF;

3. From Firewall, turn the Firewall OFF;

4. Then click on Settings;

5. Click on Settings and disable On-access scanning from the Antivirus box. Disable if for 30 minutes. It will enable back when this period expires;

6. Then disable the "Active virus control" in the lower part of that same window;

7. Then click on gear, select the Firewall module and from Advanced disable the Intrusion Detection system;

8. Click on gear, select the Privacy module and perform the following changes:

- turn ON the Show Bitdefender Toolbar option;

- turn OFF the Scan SSL option;

- turn OFF the Protection against fraud option;

- turn OFF the Protection against antiphishing option;

9. Close the Bitdefender window;

10. Open your Internet browser, click on the tiny black marker from the central left spot on top of the page in order to expand the Bitdefender toolbar and turn it OFF;

11. Close the Internet browser and check if the issue still occurs.

If the issue is solved by disabling all those modules, please try to enable just one at a time in order to check which of the Bitdefender modules is causing it.

Please let us know if disabling any of these modules solved/reduced the slowdown, and which of them it was.

Looking forward to your feedback!

Don't you read messages from people? It is f*cking autoscan related problem. I got this problem too.

tmaesing

as I have reported in my support call and a lot of people here it is a problem with autoscan!!!!

It is really frustrating to get a lot of promotion e-mails but no hotfix until now. This should not

happen with the new Photon...

Don't you read messages from people? It is f*cking autoscan related problem. I got this problem too.

If you read through this thread, people have been posting about other potential causes other than autoscan. So it makes sense to post those instructions. They will help isolate the issue(s) manifesting on the different systems categorically. When that is done, it can be recreated with the support tool running. Then with the logs sent in they will have more chance of fixing the issue(s) without the extra misleading information the logs would otherwise contain.

tmaesing

Hi,

there is definitively a problem with autoscan.

But there is a second problem, the update slows down the maschine also very much, for me too much. I have had

Norton Anti Virus and Kaspersky on the same maschine, so I can compare, both are better at this point.

Best regards

ragbuster

Just to confirm, once autoscan is switched off I have not experienced this issue so bitdefender support you need to look at what is happening after the software downloads its new daily definitions. During the 2nd autoscan causes this issue.

I was having a similar problem with Firefox until V 23.0 than Firefox started to use memory like it was going out of style virtually crippling my computer's (multiple) Internet surfing ability. After some fiddling around I thought why not just do an uninstall and clean install of Firefox. However, the problem was how do I do this with the minimal amount of time spent given my 25+ add-ons and hundreds of bookmarks and passwords. Anyway I gave it some thought drank a bit of coffee and gave it some more thought. After coming up with a plan I executed it without too much effort and time involved. Viola Firefox is now running better than ever.

ozziebear

Problem still remains. Every time Autoscan finds some cookies and 'disinfects' them, my computer slows to a crawl and must be restarted, but of course, even this is painfully slow.

killmeplease

i got the same problem, i let my PC idle around 20min, autoscan start and when i get back, FF freeze and other programs run very slowly

I turned off autoscan and everything were back to normal again.

Thanks for that. I uninstalled FF today, I left my settings intact and reinstalled. Running much better now. Actually, I'm running the nightly build of FF x64 and really liking it right now.

Mines to do with Autoscan.

Got this update from the support call:

In order to optimize the resources usage, Bitdefender uses a technology called

Smart Database - it indexes all the files and does not scan them if the file

have never been accessed since the last scan.

This database is created by scanning, the Auto Scan being the primary factor.

Given that it slows down the computer, please run a System Scan with

Bitdefender - it will fill the database muck quicker and the Auto Scan will

use less of your resources.

Please let me know if this improves the speed of your PC.

I performed the full system scan last night and so far this morning my computer is fine. Will keep monitoring it though.

I reinstalled BD to see if this might fix the autoscan problem. The first thing I do after a reinstall is run a full system scan. It was fine for 4 days but now the problem is back once again. Same scenario. Events showing in the widget and computer loading web pages and programs slower than molasses including BD.

I should also add that the events which cause the slowdown are always cookies disinfected by autoscan. Other events, such as reboot requests have no effect on computer performance.

ragbuster

Spoke too soon, disregard my comment. Computer still slows down after it starts a background scan. Back to switching off autoscan for now.

Georgia

Hello all,

Thanks so much for your feedback so far.

I will need a few support tool logs gathered while you managed to replicate the slowdown while the Autoscan is ON.

In The New Bitdefender, the support tool executable "supporttool.exe" is found in this location:

C:\Program Files\Bitdefender\Bitdefender

Run "supporttool.exe" (right click on "supporttool.exe" and choose "Run as Administrator" if you have Windows Vista/7/8 ).

Fill in the required fields, check the box "Try to reproduce the issue before submitting" and select "System slowdown issue".

Now turn ON Autoscan and take all the actions to replicate the slowdown.

When the progress bar gets to the end click "Finish". A new archive will appear on your desktop. The name starts with "BDSP_....".

You may not be able to upload the archive here as it's too big so you can put it on www.sendspace.com or any other file hosting site and post the download link.

I am waiting for the necessary logs. Thank you!

Jonj1611

Why does turning off Autoscan then change the program from Autopilot to Manual? Thats the most stupid thing I have ever seen and it shouldnt work like that, turning off Autoscan has nothing to do with how the applications evaluates what programs are safe or not.

Georgia

Hi Jonj,

While on Autopilot, Bitdefender applies an optimal security configuration and takes all security-related decisions for you. This means that in Autopilot Bitdefender automatically fixes critical issues, enables and quietly manages:

- antivirus protection, provided by on-access scanning and Autoscan

- firewall protection

- privacy protection, provided by antiphishing and antimalware filtering for your web browsing

- automatic updates

This is how the program works. Thank you for your feedback.

Hi

I am experiencing the same problems as described above on my 2 computers (Windows 8 64 bits) since I have upgraded to the "new" bitDefender.

No remedy so far so I have uninstalled the software and back to Windows defender " /> " />

I am wondering why I paid a licence fee?

ozziebear

Problem is worse now! To summarize: With BDTS 2013 and Windows 8, I would get the little pop up telling me that BD had started the Autoscan Process. That was all good. FAD. When I upgraded to the new BD with Photon Tech., I no longer saw that little pop up. Autoscan would take up to 12 days to complete one cycle. In fact the only way I knew that autoscan was working at all was that there were events showing in the widget. These were always cookies which had been 'disinfected' by BD. As soon as I saw that, I knew that my computer (browsers and programs) would be unresponsive and would have to be restarted. Now, all of a sudden, that little pop up is back and again, as soon as I see that, I know I will have to restart. I have a feeling that this all has to do with the Photon Tech. I have run 4 complete system scans since my last reinstall and have seen no benefit from the Photon Technology.

Same here. I've used Bitdefender for the last year or so and it has worked to perfection until the "new" came along. Updating and throwing my money away has been a disaster on my Win 8 x64 machine. I also will probably call it an expensive lesson and go to something else. I reinstalled BD and for several days it worked fine and then it reverted to it's old ways, a delay on everything I run, whether it's the control panel or a new window in IE.

I wish I could download the old version and just run that for the life of my license and then I could buy something else.

antikythera

Bell1 - You can download the previous version from here, nobody is stopping you apart from yourself:

http://forum.bitdefender.com/index.php?showtopic=35494

To have a clean base to install it on, run the New Bitdefender and 2013 Uninstall tools in windows safe mode. If you run them in normal mode they cannot clean off locked files that are still in use.

Jonj1611

I have taken it off all my machines apart from my main machine and thats only because I have turned off Autoscan, its clearly an issue and if you have ever experienced it, its so frustrating, it just shouldn't happen, I notice a lot of people who are having issues have Windows 8

Georgia

Thank you all for reporting this issue.

If you decide to reconsider our product please post back at anytime with the result of the Bitdefender support tool and we will be able to assist you further.

Looking forward to hearing from you, have a great day!
