that both read from the hard drive and make use of RAM and the processor.

The Avast Boot Time Scan checks for virus activity and CHKDSK (CheckDisk) checks for and repairs bad sectors (damaged sectors), and the MFT (Master File Table) or FAT (File Allocation Table).

So what's the advantage of doing a boot scan compared to just a regular scan?

Boot time scan is performed before the operating system is loaded. Some rootkit is a kernel-based so a boot scan is useful.

Boot Time scanner can make the job of cleaning and deleting an infected file a lot easier.

Disadvantage of Boot time scanning: Takes a little bit of time to load the OS. Depends on the scanning engine of an antivirus though.

If I'm not mistaken, you can just set Avast to schedule a boot time scan when you want it to do so.
