Maybe this is because your antivirus program doesnt go the extra step like norton 360 and inspect each download, even .exe's (executable install files) are scanned after download
In both forms (after download / download inspection by norton 360, AND when scanning the file within its folder/ downloaded location), the download was marked by Norton 360 (which costs $130 au dollars per year) as a "Heuristics Virus" - with SUSPICIOUS.AD detected
Upon inspection of the download itself, it detects this

"SUSPICIOUS.AD" component which must be new - as the faulty component and prevents any installation - however the file stays intact at the location on disk it has been save to
Furthermore, once you scan that download location,
e.g drive m-Soundspectum Downloads/g-force4.0b3.
It is detected once again, but this time norton 360 actually removed the risk (the whole file, installation package and all)
Considering ANDY just recently made changes to the g-force 4.0 BETA 3 to add signatures to the .exe and standalone components
"- Now signing exes and screen savers to prevent anti-virus false positives"
It seems this was not configured correctly or in a format that Norton 360 will allow G-Force4.0b3 to operate.
For starters our antivirus hasn't picked up anything that wasnt there in the first place, and any exe file or download with something built in inside of it identified as "SUSPICIOUS.AD" would ring a bell in any antivirus software that is half decent.
Thanks

, but as mentioned by other SS platinum beta testers, its actually an issue that Andy and the SS team will need to address internally as part of the install file package (.exe) and correct for the greater good of all G-Forcce 4.0 users
Maybe it just that your "Download for FREE or inferior generic antivirus programs" won't find the SUSPICIOUS.AD string because they don't go the step further to inspect downloads as safe or dangerous, or it simply doesn't use heurisitc protection or detection mechanisms, etc.
Please correct me if you think im wrong, but the SUSPICIOUS.AD component would NOT have been found if it wasn't part of the downloaded ex file install package in the first place

- obviously introduced by andy in GF 4.0beta 3, or mistakenly named, wrongly configured, etc
Im sure Andy knows how to phone Norton's Symantec Parent company if this continues to be a problem for SS customers / license owners
