I have same problem...0 -
The said issue is occuring again since last two days. Bitdefender detects DNS servers assigned whatever manually or DHCP as port scan attempt. But there is no reply

Same for me with my DNS servers even when added to whitelist.
I brought this issue up a month ago and I'm still waiting for a response to my pm's and a solution
" />0 -
I tried everything (including adding DNS servers to whitelist). The only option is really set port scans blocking feature to off. So now I have disabled port scan blocking (but this setting is forgotten after reboot), renamed bdtl.dll, disabled automatic updates and lack of a scheduled scans. I'm seriously thinking about returning to BDIS 2011...

Now the frequency of said issue has been increased, but still there is no reply

Bitdefender display pop-up for Port Scan attempt, but the Events are not highlighted for them may be because they are classified as "Warning".
0 -
Those pop-ups are just notifications. The "scan" is blocked for the DNS just until the rule is created. Considering this, you should not have any interruptions on the internet connection.
Any of you encounter any issues with the internet connection when or after the notifications are displayed ?0 -

The rules for DNS over UDP and TCP are already created by-default and set to "allow" but even then the pop-up displayed. Kindly see the attachment. I also faced the said issue by assigning DNS either by DHCP or by entering the DNS manually and also using different ISP. And after the pop-up appear, the internet browsing reduced very much i.e. web pages load very slowly, but I can download only from torrents.

Hi Cristi
Are you saying that the problem should have been fixed in a recent release? If that's the case then I'm still seeing this very regularly...

Same thing overhere, frequent popups, about blocking a port scan of the Google DNS server.
No problem with blocking a port scan, but the popup is quite annoying. Is there any way to get rid of the popup?0 -
Hi Cristi B.
I have the exact same problem can I send you the log file?
Please reply
Thanks0 -
Hi
Yes please. Follow the steps from that article and send your log via PM.
Thank you.0 -
Hi
Thank you for the log.
I've send all the data to our development team and they are working to fix this issue.
Th update will be delivered via automatic updates without user intervention.
As a temporary workaround, please disable Block post scans from Firewall-Settings. Don't worry, the firewall will still protect your machine.
We are sorry for the inconvenience. Thank you in advance for your support and understanding.0 -
Even i have same problem. Hope you guys fix it.

Hi
We are very sorry for any inconvenience that we may have created and we rest at your disposal for further information.
Thank you for your support and patience.

It started happening while I was on eBay, so I thought it was them. So no one is actually scanning for open ports? or trying to harm my computer?

Hi and welcome to our forum.
You machine is safe, the firewall is not turned off.
It just a small issue that it will be fixed with a product update.
Until then, please make the following settings in the product:

Any idea on when this fix will be implemented yet?
I'm still getting this problem and it's now some 4 months now since it was first reported" />
2011 seems to have been a poor year (IMHO) for Bit Defender, I had serious issues with BD TS 2011 x64 which never worked for me properly and although it has lesser issues BD TS 2012 x64 is turning out to be pretty poor too

Hi Nightgaunt
The Dev. Team is working to fix this issue, I can not provide you an ETA for this.
It will be fixed with a product update soon.
Thank you.0 -
I have the same issue. Mostly it happens when I click the back button on either of my browsers (IE9 and Chrome). Even otherwise it happens occassionaly and the detected IP is my ADSL modem's 192.168.1.1.
Also, my Windows explorer.exe keeps freezing while surfing. Why? No error message. I have to keep Anti Phising and Safe Search disabled or else surf at a crawling speed with 1 Mbps connection.
Did you'll release a beta version in a hurry without proper coding and testing?
I have already posted in the thread about Scheduled scan feature missing issue.
This is my first disappointment with BD in 3 years.0 -

Hi Cristi
No, it isn't fixed - I'm due to send you a log for a Trufos problem and I'll try to capture it in it.

Still not fixed. At least suggest to the developers that they could allow us the option to turn off the notification for now. As a novice programmer, I know they could easily program that into the code in no time. Also, I am not about to turn the option "block port scans" off, and I suggest no one else does that too. You never know if you might be providing an opportunity for someone or better yet a bot to footprint and collect information on the ports that you have open. Especially, if you have any specialty ports open for inbound connections. Honestly, it would not be so bad if the notification did not appear at the top of all open windows or minimize me from full screen mode.
Thanks,
Alex

will this problem cause lag spikes in internet usage, basically the usage goes to 0% ?

Still got the same problem here too, yet another problem that has not been resolved within a reasonable time frame
I mean almost 4 months since this thread alone was started, is anyone actually fixing anything in Bitdefender these days?
That's a third of someones license time, totally unreasonable tbh and I doubt I shall be renewing again, your software has been seriously buggy in both 2011 and now 2012.0 -
I've just discovered that due to this issue if I have block port scans switched on this disconnects my new tv from the dnla server even though a firewall rule is set up to allow everything on the the tv ip address.
BD 2012 TS x64 constantly blocks port scans from the ip addresses in my own network.
Since changing from BD2010 to 2011 and now 2012 I've had constant issues some of which have been on going for far too long now.
Just how many employees does BD have working on these problems? I suspect in some cases none!0 -
Another month has passed since anyone from BD posted to let us know the devs were working on a fix for this issue.
No fix yet, nothing to keep us informed and worse still no deadline for a fix!
Can someone at BD please give us some information, you must know by now what is causing this issue and at least have an estimate of when a fix will be implemented?0 -
Just uninstal Bitdefender and switch to alternate solution, since they said we fixed it and they actually NOT. Thanks Bitdefender. 1 loyal customer gone forever.

Not that far behind you. Seriously, I am sick and tired of firing up a program for the first time, and within 5 minutes finding features that I really need to use yet the developers not only never even considered, but can't be bothered to fix." />0 -
Hi guys
Thank you for your feedback.
Please follow the steps explained in the article below and send me via PM the generated log file:
http://forum.bitdefender.com/index.php?s=&...st&p=119338
I need to look for file version. In my opinion, in some cases, this could be generated because you don't have the latest product update installed.
So if you still encounter this issue, please send me the log.
Take care.0 -
@Chris, the amount of time this issue has been going on for is a total disgrace.
As you are aware I've solved the problem myself by uninstalling BD2012 TS from my two pc's and using a competitiors internet security package which not only works but also found a number of trojans on my machine that both BD2011 TS and BD2012 TS did not find.
I will never use your software again let alone continue to beta test it for you, the reasons?
The slowest customer (lack of) support I've ever seen and the fact your software has more bugs than the Amazonian rain forest!
No logs from me I'm afraid, you did however get my money and a year of my time which I think is more than enough!
Not very constructive I'm afraid but hopefully some good feedback to take back to your marketing department and management.0
