Hello guys of Bitdefender staff! 
I'm using Bitdefender 2010 B1 on my main machine and it works like a charm! I decided to install BD 2010 even in my laptop that uses Windows xp. The problem is that on the laptop it was installed 2009 TS version of BitDefender. First i tried to uninstall it from "remove application" window but it gived me an error, so i tried the uninstaller. The uninstaller removed only partially BD 2009 installation. I installed 2010 version over the 2009 and it seems to work but many entries of 2009 version are still here. Indeed in "remove application" window i have "Bitdefender Total Security 2009" string again. If i try to uninstall clicking "remove it" it gives me the following error: Code error 2753.
What should i do?
Thank you!
