The two files that caught my eye are these
C:\Documents and Settings\Kirsty Margaret\Application Data\MIDIMAST.INI
C:\Documents and Settings\Kirsty Margaret\Application Data\wklnhst.dat
These may be legit files but they pull no results on any search engine that explain what they are!
You can locate them in that folder and right click each and Select properties and see if they are associated with anything legit on the system!
You can also have them scanned at these 2 sites
Other than that,I see little or nothing wrong!
Have you Installed a firewall yet?
Also another good program to assist you
Please post back and update me as to how the system is running and if you notice anything else wierd!
All the files you uploaded were examined by some of the best in the Antivirus Buisness!
Each said,it was a nasty and intentional Hack and not of the usual type!
So please be careful with MSN and any other Messenger program as well be careful Opening Emails!
If I can track where the files came from,I will be more than happy to pass that info onto to you and the proper authorities!
Please post back with any comments and an update as to how the PC is running!
