BD Antivirus quick scan takes long time with .pyd files


Quick scan used to take about 10 seconds, but it's now taking 7 minutes because it's scanning a file with a name like


c:\users\<username>\appdata\local\temp\_mei54002\windows.conditional.pyd


I haven't been able to find out what this file is, but the anti virus scan doesn't identify it as a virus.


Is this a known problem?
