Malware scanner seems to be freezing

I have Firewall Pro on Windows XP Home and when I run the malware scanner it seems to scan fine for a few minutes then it stops and says that the scan completed up next to where it says “Scan My System”, but the scan status says “Scanning: C:\blah\blah\blah” and appears to be frozen. The options in the lower right corner of the box also change from “Pause” and “Stop” to “Exit”.

When the malware scan is complete does it usually still display “Scanning” in the scan status?

Yes its normal. If it says scan complete its done.
