How Can I Uninstall Nod32 Antivirus From Windows Xp

So I ran its setup exe file where I found an icon for removal, but during removal it gives this error:

‘Another application has exclusive access to the file ‘C:\Documents and Settings\All Users\Application Data\ESET\ESET NOD32 Antivirus\Logs\virlog.dat’. Please shut down all other applications, then click Retry.’

I restarted the PC, but this keeps on happening. Then I terminated all processes related to ESET NOD 32 in Windows task manager, especially the ’ekrn.exe’ process, which I think is related to this antivirus.

Still I am getting this error and I am not able to uninstall it. Tell me what to do.
