@Mark – Are you sure that your tone is appropriate? VirusTotal’s scan with 55 engines, including Avira and Vipre, report the software as safe. Are you really surprised that a program writes-to, deletes-from, or otherwise modifies-files-in its OWN installation directory??? Perhaps, you suspect the program’s developers are hacking themselves.
I understand being cautious, even sceptical, when installing software but a bit of research and common sense should be applied before firing both barrels. That makes for a more amicable web experience for all and keeps you from appearing, well… you know.
