Deleting MGtools files

Hi,
I had a problem with malware, a helper guided me to deal with it using MGtools among other programs. Once the malware problem was solved I uninstalled all the programs (everything went fine). Then I had a problem with a software and I was advised to install again MGtools and use its logs. Once the problem was solved I deleted Mgtools, but still remain lots of files in C:\ created when installing MGtools and some Thumbs.db files in many folders all around the pc. I just would like to get rid of all these files.
Windows XP, home edition.

Regards

 

Thanks for reply.
I’ve seen that tread before and tried it, it didn’t work. I uninstalled all programs OK when finished my problem with malware. Also in this instructions; just says to delete Mgtools. I deleted Mgtoolsexe without problem but still remain lots of its files in C:\ and Thumbs.db all around the pc. I don’t recognise any of these files, so I don’t know which one I can delete and with one I shouldn’t.
