What Is Unauthorized Access Logged Norton Deleted Profiles And Security Alerts?

Deleted Profiles and Security Alerts? - what is unauthorized access logged norton

Three days ago, I have a second user account with administrator privileges. The closing of the computer for automatic updates and when I return to my new account has gone home. All my documents are gone. I am running Windows XP SP2 and Norton Internet Security.

Nothing in the trash. When I tried to understand what happened, I started to have the files from Norton. I have in my alert file found several "unauthorized access Identified" warnings (36 10:42:21-10:42:23). There were 63 more cases 11:06:03-12:07:11. This is the whole time, which would have lost the profile ... or maybe a little later in the day. There was more connected to the next time I returned to my computer.

Read all warnings as follows:
Cast: C: \\ \\ \\ \\ \\ \\ \\ \\ WINDOWS \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\system32 \\ \\ \\ \\ \\ \\ \\ \\ winlogon.exe (PID = 664)
Target: C: \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ Program Files \\ \\ Common Files \\ \\ \\ \\ Symantec Shared \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ ALUSchedulerSvc.exe

My question is twofold: it was someone hacking my computer? And it is a way to recover my lost data?

Thank you.
