Can anyone shed light on the CRCAB.exe process - what is it and how do I get
rid of it (I suspect its a trojan)

When I google a search the result is "do you mean crack.exe" so the web
doesn't know about it!

Very puzzling

Please submit CRCAB.exe to Virus Total --
http://www.virustotal.com/flash/index_en.html
The submission will then be tested against several different AV vendor's
scanners.

Another way to submit is to send the suspect file to the following email address
scan<at>virustotal.com
{ replace <at> with @ } with only the word SCAN as the subject.

Please post back the EXACT results.

The McAfee module in the Multi-AV front end should get it.

Dump the contents of the IE Temporary Internet Folder cache (TIF)
Start --> Settings --> Control Panel --> Internet Options --> Delete Files

Dump the contents of the Mozilla FireFox Cache { if you use FireFox }
Tools --> Options --> Privacy --> Cache --> Clear

Download MULTI_AV.EXE from the URL --
http://www.ik-cs.com/programs/virtools/Multi_AV.exe

It is a self-extracting ZIP file that contains the Kixtart Script Interpreter {
http://kixtart.org Kixtart is CareWare } three batch files, five Kixtart
scripts, one Link
(.LNK) file, this PDF instruction file and two utilities; UNZIP.EXE and
WGET.EXE. It will
simplify the process of using up to 3 different Anti Virus Command Line Scanners
to remove
viruses and various other malware.

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in Normal
Mode. This
way all the components can be downloaded from each AV vendor’s web site.
The choices are; Sophos, Trend, McAfee, Exit the menu and Reboot the PC.

You can choose to go to each menu item and just download the needed files or you
can
download the files and perform a scan in Normal Mode. Once you have downloaded
the files
needed for each scanner you want to use, you should reboot the PC into Safe Mode
[F8 key
during boot] and re-run the menu again and choose which scanner you want to run
in Safe
Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive
PDF help
file.

To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close

Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }

NOTE: You may have to disable your software FireWall or allow WGET.EXE and/or
FTP.EXE to go
through your FireWall to allow them to download the needed AV vendor related
files.

I carried out the suggested procedure (took all night) but still had the
CRCAB.exe in the process list (Even in safe mode) so the various removal
tools failed to delete the file. The process in task mgr refuses to die when
terminated (it seems to respawn itself) and proceeds to take up to 90% of the
CPU time.

however I made boot dik and ran the sophos scan from dos and this deleted
the CRCAB.exe file

When windows was restarted a message saying that the CRCAB.exe was missing
(so something is still trying to load it - Reg entries?)

Anyway its gone and the PC is back from the dead

Maybe you need to include a DOS scan instruction in the procedures

Question - Do you need the full .LOG files from the various scans Ill mail
if necessary
