NOD32 found Win32/PrcView. However SDFix is not malware certain files that are used by the tool can sometimes be detected by AV scanners as possible malware. The main reason this happens is down to a number of reasons such as what file(s) it uses, what is altered/accessed, does it do anything to the registry and so on. Win32/PrcView, is a program that scans system processes and is capable of terminating these processes, while this can be seen as malicious, SDFix needs this to perform its task. AV products in general are unable to properly identify these tools correctly and flag them as malware just to be safe.
This means you have a very good AV scanner. However if you wish to run the tool you will either have to disable NOD32 for the duration of the fix and restart it as soon as it is finished of you can instruct NOD32 how to ignore this tool and ignore its actions while it performs its task.
