Just a FYI for those that use these applications.
Bitdefender Antivirus does not play well with K-9 Web Protection. It seems to hose the DNS and you can't browse the web, update anything etc.
I recently began installing Bitdefender on clients' computers as my A/V of choice. Problem is that many of my clients use K-9 Web Protection for their parental control software. I don't know what exactly the problem is, but when they are both installed, and K-9 is not in Admin mode (where it allows everything), DNS does not work.
I can ping any web address by IP address but it fails when trying by domain name. nslookup fails as well. I tried manually changing the DNS servers to opendns but that didn't help.
I once had issues with Kaspersky blocking K-9 because K-9 plays with the hosts file, so I just excluded the hosts file from Kaspersky and all was well. (I don't know if that is still necessary) This workaround does not work with BD. I excluded the hosts file, the K-9 application folder and the driver file but it still does not work. I manually checked the hosts file but it's the standard one. The logs in BD don't show any viruses being detected, just that the updates failed because they could not resolve the server's address.
If I uninstalled either one, Bd or K-9, there were no issues, but if they're on together, it's down.
I saw on K-9's website that there is a known issue with BD and K-9 (I hoped I can manually take care of that as above) and K-9 tried to work with BD but they need to hear it from the customers, so I should contact BD support to tell them to whitelist K-9. I did that but they replied with some baloney about running two different security solutions at the same time degrades performance etc etc. and they do not troubleshoot if the customer has other security solutions in place. They were also saying that I shouldn't run MBAM at the same time for the same reason. They didn't even want to look into the issue at all. (K-9 is NOT an A/V app, and neither is MBAM)
The problem is that it doesn't seem to be "blocking" the program per se, just something is going on with DNS.
In any case, if anybody has any ideas, I'm all ears. Otherwise, I'll have to use another A/V from now on.
 
Thanks for that.

I find BD's attitude a bit concerning. [emoji52]
Beginning to think my loyalty move to emsisoft was a good idea.
 
For those situations with K-9...what if you turn off the content filter component of BD?

Seems logical that http proxies (and differening DNS services they rely on) might collide.

This is Bitdefender Antivirus Plus. I don't think it includes content filtering. I couldn't find any setting for that.
 
It still has some browser protection modules...anti phishing, that online banking component, and something with the name "search" in it...search protect or search assist or something....try disabling those.

Lmao...... Big style !
Bitdefender uses conduit search protect ??!!

You heard it here first.

(I know, I know that's not what ye oldy meant, but it just tickled me anyway).

Tried that. Disabled basically everything: Idle Scan, Antiphishing, On Access Scanning, Active Virus Control, Search Advisor, Scan SSL, Fraud Protection and Phishing Protection. I basically turned it off but nothing changed. The only way to get online was by disabling K-9 by going into Supervisor mode.
 
did you reinstall k9 after bitdefender?

Bitdefender was installed first, then K-9, and Internet doesn't work.
Uninstalled K-9. Tested and worked. Reinstalled K-9, didn't work.
Uninstalled Bitdefender, tested and worked. Reinstalled BD, didn't work.
