i got some software and when i tried to install it nothing happened. i checked running programs and nothing new so i deleted it. but now for some reason when i try to run sygate i get a message that say "smc.exe is not a valid win32 application". i uninstalled ran adware took some stuff off. re-installed sygate and samething again. i disconnected it from internet, i'm afraid to connect not sure what might be trying to get out. i never get on without firewall. i don't have any virus software but i know there is free scans online. anyone have any advice? should i just connect and do a scan for free or download free software then disconnect? or is it just something weird that i need to fix. i've been running sygate for a few years on xp and have never had this problem. sorry to be long winded but figured the more info i give the less questions till i can find any answer

thanks in advance
