There is no log generated as it just replaces the MBR and nothing else
Thanks for the info. That's contradicts what I was told elsewhere, that a log would be generated. Who is correct?
Did you read this page ? http://www2.gmer.net/mbr/
No, I didn't (thanks for the link). There's no link to that link from the http://www2.gmer.net
homepage that I can find, only a link to download mbr.exe. I guess that answers my main question, except... I've searched through it and found some references to mbr.exe near the bottom under "Detection and removal" and "Update". According to that info, there are several different versions of mbr.exe, and the author is from gmer.net (not avast.com): "Stealth MBR rootkit detector 0.2.2 by Gmer, http://www.gmer.net
"; "mbr.exe version 0.3.1 or newer"; etc. Also I see no cautions about its use, i.e. why it's risky. My impression is that mbr.exe is only used to remove a few known mbr rootkits, not to find/diagnose them, nor to repair the mbr in general. That contradicts the tech guru advice I'm seeing elsewhere that mbr.exe can be used, in general, to repair mbr errors. So are we talking about the same mbr.exe or are there two different authors/software using this same name?
So it seems that the cat's out of the bag already, running rampant in the wild, and it's now time to provide full documentation and op instructions for everyone to read! Otherwise expect an increasing stream of complaints and queries about it.
This programme has been out now for many years and you are the first I have come across that has voiced any concerns about it. As for running rampant I fail to follow you - this is a tool used in malware removal forums by people who know what it does, and when to use it. If you had concerns at the time why did you not ask the person helping you
It has gone beyond malware removal forums, into general purpose forums and newsgroups. Yes, I asked the persons who recommended it for details. I also asked the gmer author for details. None of them responded. At least I've got you on the hook...
