Hi, I'm looking for some help / reasurrance about a potential security issue on my PC and found my way to this forum via Hijack this.
After leaving my computer switched on overnight and finding it unexpectadly restarted i checked the system event log. I have noticed a large number of 627 change password failure audits from both NT AUTHORITY\SYSTEM and NT AUTHORITY\ANONYMOUS LOGON.
there around 30 failed 627 events usually followed by a succesfull change all happening within a few seconds.
In all cases the target account is mine( the only and administrator account).
I'm not really sure what i'm looking at but its got me worried as i thought this message was only generated by a user attempting to change password.
The other thing is that the large number of failed events seem to coocur every half hour or so. Is someone trying to hack my machine or is it a normal error message.
I'm have attempted to scan / clean my system with all the suggest utilities.
I have bitdefender 2009 and ZA installed and up to date.
Some experienced help would really be appreciated, especially if someone has time to go over my hijack this log.
thanks in advance
