In response to the "so, is it safe" statment.. May want to check into it on your own.. I'm not flaming.. But, personally, if I see the potential for compromise, I check into it, research, find out what the reports mean, etc..
But, for those of you too lazy to do it:
SpamTool.Win32.Gadina.d is listed as a trojan, it's malware. What, exactly it's looking for, or exactly what it's doing, can't be determined without examining the file, which I don't care to download. Reference ->
http://research.sunbelt-software.com...threatid=46075 for more information.
The VIPRE.Suspicious hit is explained here ->
http://research.sunbelt-software.com...threatid=93377
So, in other words, if you want an address-stealing trojan, and unknown (yet low-risk) Suspicious hitting files assoicated with a download and blind install, go for it. If you don't trust it, then no, I suppose it's not "safe"..
But it's all opinion. Some may say it's cool. Some may say it's not. It's up to you. It's your computer, information, account. =)
