yeah, so frustrated with eset smart security 4 regarding connecting with my router that uninstalled it. tip for those who want to completely uninstall it is to use the provided uninstaller then download the esetuninstaller.exe to remove it entirely in the system.

Hello.This article was extremely fascinating, particularly since I was looking for thoughts on this issue last Tuesday.

I have JUST downloaded ESET smart 4 onto a clean install of XP pro and so far it is working perfect. By doing this I am giving ESET the best chance of doing its job, in the event I get any problems I will report back. Please note: I do not have the time to ‘fiddle’ with settings so it is all at ‘default’ level.

Hey folks,

Have the same problem here. Going to use Windows 7 firewall again. Eset caused my router to reboot instantly when I tried to enter it through browser.
After the router rebooted ESET noticed it as danger, blocking every connection to it, forcing it to reboot again. And again. And so on.

No other software firewall caused this behaviour.
This is simple DHCP renewing. Their solution was to disable the router dhcp or going deep into menu and entering a rule for the router IP to allow any traffic from and towards it, and to disable IDS for it.

Same problem here. Worse yet, uninstalling ESET failed (I got an error message about the uninstaller not being able to reach the ESET Kernel) and made it impossible to use any networking at all.

It somehow obtained control over the computer’s firewall system and won’t let it go, WIN XP firewall won’t work any more. It reminds me to the extremely difficult process of removing Panda Antivirus some years ago. I had to reinstall ESET then deactivate firewall protection and that worked for some time. But even then, a day it just decided to stop working.

Really really dissapointed with all this. I can’t connect to anywhere with that computer anymore.

Resetting the winsocks didn’t work for me. Now I’m formatting and reinstalling from scratch. I’m never using ESET again!

I have to agree on the criticism. I have noticed these issues back in the 3 series and after removing ESET Smart Security,, I decided to try and reinstall (after good 6 months) because I absolutely loved it’s performance in the past..

My issues are not with internet connection as a whole but are definitely tied to winsock. There is nothing I haven’t done to re-set to clean up,, to modify,, so on,, the issue remains…

Considering the magnitude of the problem I agree that ESET should be A LOT more proactive about resolving this…

Every version of ESET’s firewall, from v3 to v4, has problems with basic issues such as renewing DHCP IP addresses. ESET seems to be hiding their heads in the sand. The documentation and knowledge base provide no help at all on such issues.

Installing Vesion 4 over version 3 causes serious problems, unistall and reinstall will fix many problems that occur if you install over an existing version. (ESET should check in the install script and not allow this!)
ESETs firewall is excellent in V 4, just because it finds high risk behavior risky isn’t a reason to knock it. There is no doubt that better explainations and faqs about certain conflicts should be documented for easy review, but if you configure correctly it is a fantastic product even running on a server where it “should’t be installed” and where it has to deal with very high traffic levels it works great. I love it, and V4 is a big improvement over 3 in my experience.

I had Firefox and Thunderbird logon problems. I found switching off Peer Guardian solved all of my problems. This is one of the problems I had that ESET picked up: 05/03/2010 11:14:51 Detected DNS cache poisoning attack 192.168.0.1:53 192.168.0.100:1290 UDP and also 16/03/2010 09:57:49 Packet blocked by active defense (IDS) 192.168.0.100:1275 78.33.33.73:80 TCP . ESET have suggested that I allow them to connect remotely to my machine and they will “investigate and remove the problem”
