Someone seemed to hack into my computer and put new settings, and files, and locked certain things so i can not access them. What should i do?
It all started when my password was changed. I changed my password, and then thought everything was fine. But recently i have discovered i am not able to access certain administrator settings and there has been some files and programs downloaded, and settings are very different in almost all of my applications, and system settings.
I am the only user, i only have one log in name, and no one shares the computer. I had the laptop since 2009 oct. And this is my first problem. I dont know what to do. i would delete and restore it new, but i want to make sure this wont keep happening.
Also there is a little american icon in the top right when i log in now? dont know what that is either.
If someone can please tel me any suggestions on what to do because i know someone is messing with my settings, and whole computer and i dont know what to do!!
i have antivirus and mac keeper as well, and i had both before this problem occured.
VERY CONFUSED!!
HELP!
MacBook Pro, Mac OS X (10.7.1)
