--------------------------------------------
I have been plagued with remote attacks since I bought this newly built computer from the store. Formatting; including low level reformat, resetting cmos jumper, and removing all components has been done by 6 different people but to no avail.  It seems like I am being  compromised when I do my windows update; sometimes right away and other times I haven't noticed the problems for a week. I do not use Internet Explorer.  I install anti-virus programs prior to accessing the internet for updates. I have tried every anti-virus, spyware, firewall, registry check and they are great for a few days (if even)
and then they become disable. Oh and just to show you how desperate I am for help, I purchased most of that software! LOL  Install logs look like I am installing fake updates so perhaps a browser hijack?

A couple of the problems I experience: Loss of Local Admin priviledges and eventually a complete D.O.S. (by NT AUTHORITY\NetworkService?).
Registry continues to change with added users and SID's.
My C: drive shows up as a file folder and no longer a system one.
Despite disabling remote/terminal apps from services.msc my registry
and logs become filled apps that appear to be remote access apps.
3 times now I have lost access to my CD-rom and DVD drives. I have CD-Rom this time but DVD and Floppy won't work.
Packet sending logs with reference to streaming.
Although my RUN ----> services.msc show apps as disabled, a ms-dos prompt shows them running with demand starts.  


It's like I don't have access to my real C: drive if that makes any sense.  I can't explain it any other way than to say that I feel like I only have access to and see a fake drive.
This is the same with anti-virus programs. They look llike they are doing their job but it appears they have been come compromised. Most of the time I am unable to access online scanners.

Weird things like this showed up today. Maybe it's normal?

I installed Nortons 2005 and it worked long enough for it to detect

Spyware.WinKeyG
Hacktool.XScan
Bloodhound.Exploit.6 (Norton's stopped working shortly after this)

Firefox had a virus detected so I'm using Netscape for the immediate time. I dont' know if this is normal but my Netscape opened up to this url:

Thank you,

I gave this a difficult rating because I have taken this computer to different computer stores and they have not discovered the problem.
