Hello!
with the last clamWin version, in Windows XP.
Yesterday before leaving I did the scan of all my hard drive (C, D, E, F).
This morning, coming back, I red the windows error that the system is going low in virtual memory...
maybe the message was: "Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. During this process, memory requests for some applications may be denied."
I had 4 or 5 messages like this, and after, the last message was the application error of ClamWin.
I am sorry if I can't be more precisely but I didn't red it with much attention... tonight I will do the same and tell if it works or not.
Seems there's a leak of memory...
greetings,
Filippo

Also today I found the error, now I can be more explicit:

FIRST ERROR:
"Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. During this process, memory requests for some applications may be denied."

CLAMWIN ERROR:
"ClamWin.exe, error in instruction 0x00d930e4 reference memory at 0x00d930e4. The memory could not be written."

it doesn't mean that clamwin was consuming a lot of memory, but it is possible. Would be good to monitor the clamwin process in task manager whilst it is happening.
