Lsass.exe Problem

This has a pagefile.pif file cannot be detected by Bitdefender.

When it infect in your computer, it infects some files and serveral install packages.

After Ghost up Windows, run Bitdefender to scan the whole system again, some viruses are detected. Howerver, some still exists and survives in some install packages (like Microsoft Office setup, etc)

After scanning finished and do deleteting all detected viruses, I reinstall Microsoft Office, suddenly Bitdefender detect this virus again and says somethings like : "multiple viruses detected ..." then computer is infected, Bitdefender crashes ! and can not be started again.

It's very strange !

I will try to upload this pagefile.pif later.

Thanks.
