Bootable Recovery Tool - How long does it take?

Sorry about registering and asking a question on the same day, but I didn't see my answer after doing a search.

 

I purchased Internet Security 2011 after a scare on my wife's PC.  Her machine became unusable after a severe infection from malware that disguised itself as anti-virus software.  Upgraded from basic AVG on my PC and was happy that the NIS 2011 CD also had a Bootable Recovery Tool incuded.

 

Giving the Recovery Tool a shot now on my wife's machine and was getting the results I expected (numerous infections).  The concern I have is that the Tool may have stalled.  It's not frozen as I can pause and un-pause the process.  However, it's been sitting at the following now for a couple of hours:

 

Checking for: DriveCleaner

Total Items Scanned: 168,403  - I can tell it's "stalled" based on this number

Total Risks Detected: 11

 

The risks include the following:

SecurityEssentialFraud

Trojan.Gen

Trojan Horse

Downloader.Ertfor

W32.Harakit

Trojan.FakeAV

Downloader

Downloader.MisleadApp

Trojan.FakeAV!gen29

Trojan.Gen.2

Infostealer

 

Ouch, I know.  Anyway, I was curious if it's supposed to take several hours for the "Checking For: DriveCleaner" part.  I don't mind leaving this PC on (for several days even) to do this process if needed since we'll be headed out of town.  This is an older, single-core PC running Windows XP and with a hard drive no larger than 80GB.

 

If this seems like it's hung up, should I simply try again?  Would I be better off with the Power Eraser?  If I use Power Eraser does that have an option to create a boot CD?
