I have run ClamWin 0.88 on one of the W2K servers. It found virus and quarantine the file.
After deleting the infected file, a different virus show up again. Following are the scan report:

As you can see, I forgot to clean the recycle bin at one time. There are many times when I scan the entire dirve D, the computer was shut down and reboot automatically which left no scan report.

Can anyone tell me how I should do further to get rid of the problem? TIA!

claiwn finds a virus in your memory dump file, which is created when Windows crashes. It may or may not mean that you have a virus resident in Windows memory. Although your scan report does not show any other errors or irregularities, I am incliden to think that the detection of a virus in the memory dump file is a false positive.

However to be absolutely sure try one of the command line scanners form other AV vendors, like sysclean utility form trendmicro:
http://www.trendmicro.com/download/dcs.asp
readme is here: http://www.trendmicro.com/ftp/products/tsc/readme.txt

I wanted to add one more piece of information. When the computer was shut down. Sometimes it hung on a blue screen. There are these words shown:

***Stop: 0x0000000A (0x7A0AFEC8, 0x00000002, 0x00000001, 0x80448F09)
IRQL_NOT_LESS_OR_EQUAL
*** Address 80448F09 base at 80400000, DataStamp 3ee650b3 ntoskrnl.exe


I hope this helps.

Jasper

OK, I'll give it a trial. Thanks,

IRQL_NOT_LESS_OR_EQUAL means there was a crash in Windows system kernel, most likely caused by an error in the driver (graphics card, printer, or on-access scanner form another AV product). Do you have anothe AV installed with real-time monitor?

I have no other AV installed. The crash happen while I am running ClamWin 0.88 to scan drive D where the OS located. It did not happen with ClamWin 0.87. But, I am not so sure it was due to 0.88. Thanks,

Jasper

I have run the sysclean and found no virus. I guess it may be just a software conflict somewhere. Don't you think if it helps if I re-installed ClamWin 0.88? See my reply on your another response. Thank you,

Jasper

Do a file system check on drive D, maybe windows crashes when clamwin tries to open a damaged file?
