I know what these are. Decrapifier is apparently ok as is PCAudit.
I can delete on my hard drive (F partition). But what do I do with the System volume info I cannot open, see, understand.
There's no point me submitting them to Eset since both are well known applications.

WindowsXP-home-SP3, NOD32v3.0.672.0

Hello, disable System restore and restart computer. Then you can enable it again.

Thanks a lot. That did the trick.
Considering that it's not on the system drive even restart wasn't needed.
