multithreaded av scanner?

is there an av and/or a-malware scanner that uses multiple threads, allowing me to scan say two hdds, usb, etc at the same time?

 

Difficult to find/google, but according to Best 2010 Free Anti Virus Software Avast should have it.

doesn't talk about 2 hdds

 

Norton AV lets you set the number of CPU threads in use but not necessarily use the for individual drives.

NOD32 uses only one core for one scan but according to information from ESET will use another instance on a different core so if you set if four different scans on four different drives NOD will launch four separate instances each running on a different core.
While it may seem like a pain all you need to do is schedule scans for each physical drive.

 

so nod 32 can scan two drives and a usb at the same time but launching three instances of the program?

 

Yes- three separate scans. Technically it will be one instance of the program but three separate windows and three separate scans will be started.
