My thoughts are that you should pause the standard shield when doing a scan with another security based application. This avoids any possible conflict it will also avoid duplicate scanning and reduce the overall scan duration. If adaware opens a file for scanning, that forces avast to first open it and scan it, if clear then control is handed back to adaware.
You don't say what the file names or locations are so it is not possible to make and determination.
What is the infected file name, where was it found e.g. (C:\windows\system32\infected-file-name.xxx) ?
Check the avast! Log Viewer (right click the avast 'a' icon), Warning section, this contains information on all avast detections.
Thank you DavidR. I appreciate your help.
(I hope my lack of knowledge is not the problem.)
Here is one entry from the Log Viewer:
516 Sign of "VBS:Malware-gen" has been found in "C:\DOCUME~1\ANTI-C~1\LOCALS~1\Temp\AAWTMP\C4059750\37BB3D\Dummy.class" file.

Regarding your comments in the first paragraph:
It appears that Avast finds the virus only after the Adaware scan forces Avast to open and scan the file. Why doesn't Avast find it earlier during the Avast scan?
My free version of Ad-Aware only scans when I do so manually. You suggest that I will turn off Avast before I run the Ad-Aware scan?
Then there is the risk that the virus will never be found?
