hi as usual, I am a new poster that only get in here to complain
.... so first things, I am very happy with bitdefender and I think it is a very good software. There, now am not just complaining 
i have read the other Vsserve.exe posts and decided to start a new one as in my case, the problem seem to be specific.
I have a laptop DELL inspiron 9400, with XP and bitdefender 2011. I have had no problems with the software for months. In the last couple of weeks I have notices that my pc slows horribly due to Vsserve.exe taking down close to 50% of my CPU. However this only happens after my PC has done a scan. I have noticed this after one full scan and the last 2 quick scans . I cannot do anything about it other than restart my machine. As I cannot close the Vsserve.exe file or bitdefender itself, it does not allows me to do so.
After a restart, the problem goes away until the next quick scan...
Restarting my machine after every quick scan is easy but cumbersom, do you guys think I need to repair the installation? Is this an issue you are familiar with and has a quick fix?
Thanks and regards,
Richard.
