The software developer is a web site called Mister Group at;
http://www.mistergroup.org/
I see nothing worrying about their web site, but when I navigate to their download page they themselves link to a RapidShare download. I downloaded the file, 'SystemExplorerSetup.exe' and it downloaded OK. I virus scanned it with my own anti-virus and it came up clean.
Strangely, they have another download link, this time from their own web site.
They are a Czech Republic development team and I notice that the Download.com software description page has no reviews although over 46,000 downloads have been made but I have to wonder if they are for older versions. There's no feedback to consider 'for this new version'. In their web site they quote Download.com with 5 stars, but that is for an older version.
What I find strange is, the CNET team reviewed this on Feb 27, 2009, but the file was added on July 26, 2010. Usually upgrades are reviewed separately as if they were new software products.
I have alerted the Download.com team to this broken link, and to the RapidShare referral.
May I say...? I'm a coward. I don't like experimenting with software that I cannot find reviews for and so personally I would stay away from this one. But that is just me, and I cannot say there is anything suspicious about this software.
Thanks again.
