Yes, it is possible for an antivirus to make a false positive. It's also very possible for the antivirus to go ape!@#$%^&* and move Continuum.exe to a quarantine folder without your consent. What about the people who had viruses, got rid of them, and SS still doesn't want to run?   In a nuts!@#$%^&*, disable (FIRST) or uninstall your antivirus. Download Cont again and install to a bunk directory (c:\ss). Copy Continuum.exe and paste it in the old directory. It should work. I've managed to mess Vista up three times in two days, this is the only way I've found to work if the antivirus flags and/or quarantines the Continuum.exe.    Spoiler! --Click here to view--Vista is so incredibly buggy. =(
