For some reason Bitdefender Total Security 2013 does not prevent the computer from entering a power-saving Sleep state while a System Scan is running. This is a bit of an issue if you ever want users running the System Scan, as it may not finish before the operating system's idle timer kicks in. Many other programs can and do prevent standby while critical maintenace operations like updates or defragmentation are in progress - especially when manually initiated by the user.
The PC I use as a workstation is set to sleep after an hour of inactivity, and this and any settings below 3 hours effectively prevent the System Scan from completing successfully. When I access the PC again, it is to do work, so I cannot leave the scan running until completed.
The software should be able to prevent standby modes when manual scans are run to ensure their completion.
I would have posted this as a Feature Request, but the forum does not allow me to start a new topic in that subforum.
PS. The operating system used is Windows 7 Home Premium 64-bit.
