Windows Security Center

It might be that the Antivirus wasn't successfully uninstalled. Please try the uninstall tool in the topic above.

Can you share the link where i can get Uninstall tool for Antivirus?

You can download this tool via this link: http://www.bitdefender.com/files/Knowledge...installtool.exe.

I can't believe that nobody at Bitdefender can give me an answer. Just another reason to not use their software. " />

It might be too late for you; but I noticed the same/similar issue (note: I'm using Windows XP SP3)...

Since having 'BD AV Free' installed, I had installed 'Ad-Aware 11 Free' (uses BD AV engine), and very recently (yesterday) I uninstalled Ad-Aware, and then installed 'Avast! Free AV'.

After installing Avast! I checked/tested whether turning off the 'shields' would produce the expected 'Windows Security Center' alert/warning, but it didn't - but, whilst checking in the 'WSC' , after turning Avast!'s Shields off, it showed a message to the effect that there were supposedly two AV programs and that Bitdefender was supposedly sill active/providing protection (which was clearly wrong). Also 'WSC' indicated that there was more than one Firewall running (and advised that can cause problems).

I had previously 'thoroughly' uninstalled 'BD AV Free' using first the Windows 'Add and Remove Programs' route, and also had run the downloadable 'BD Free Uninstall Tool' several times (and I repeated the use of the uninstall tool whilst Avast! was still installed, to no effect - WSC still showed BD Free supposedly still present/registered).

Ultimately I found the only solution was to use 'System Restore' to revert the system back a month, to Oct 25, at a point when no AV was installed (note this was after a first install of 'BD Free', but just before a second install of 'BD Free'). After re-applying the usual monthly windows/flash updates etc, that System Restore undid, the 'WSC' notices/warnings now worked as they should, both before and after re-installation of Avast! (WSC no longer showing two AV/Firewall/Bitdefender etc).

There is one thing I'm not 100% sure about - whether or not the problem was also there before installing the intervening 'Ad-Aware AV'. I suspect the problem probably was there, but I had not noticed (although I had noted that turning of Ad-Aware's AV shield/protection had also failed to produce the 'WSC' warning - but supposedly that was a 'known issue' being worked on).

Incidentally, whilst the 'WSC' was indicating the erroneous supposed presence of two AV/Firewall/Bitdefender - there was no other indication of any problems re Ad-Aware or Avast! running, nor any other problems with speed/errors etc, nothing - which strongly indicates that anything 'left behind' by Bitdefender wasn't causing any obvious problem other than the misleading/confusing/problematic persistance of BD in the 'WSC' messages.

So - a possible solution, if you encounter this problem, is - maybe to try 'System Restore' to a date before the installation of Bitdefender - but be prepared to have to repeat/re-install any updates/programs installed in the time in-between (which sometimes can cause some problems).

[Yet another bad experience - and 'black mark' against 'BD AV Free'.]
