Hi all, Whilst browsing this evening, I had a warning come up that told me my computer needed to restart, by holding down the power button and then pressing again to restart. Everything froze and had no use of any keys and this was the only thing i could do. After rebooting, i did a disk permissions repair and the very last line read: Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired. Out of all the previous repairs i have done, i am sure i have never seen this before, so i am wondering if my MBP has been compromised?? IF so, does anyone think i should wipe the HDD and do a fresh install in case? Thanks for any help.
