I noticed a weird .ini file called secure.ini keeps appearing under 'today' in my finder. Each time I drag it to the trash and do a secure empty of trash it reappears when I reboot the MacBook. I'm really worried that some sort of invisible malicious application is using it, as have used the MacBook for a year and a half and have only become aware of the .ini file very recently. I've also had to repair my hard drive recently after running a disk check when I was trying to figure out where the .ini files are coming from. I still don't know why the HD was damaged and am linking it to the appearance of the .ini files at the moment as have little else to go on. Help with any of the following questions would be greatly appreciated: 1. Is there a way to find out what application is generating the .ini files? 2. I've not used terminal before, but is this the best way to delete the files, or will they just continue to be reproduced until I can work out what application is using them? 3. Should I delete them? 4. Should I be seriously worried? I have Applecare Pro Plan and could probably take my machine to be wiped or something but am reluctant to do that if there is a better way to delete the files myself or if anyone can shed any light on the matter.
