A few targeted next steps that build on 's Safe Mode/temp-file advice and help deal with a persistent backdoor that resists normal removal.

Start with containment and evidence collection. Immediately disconnect the PC from the network so the backdoor cannot phone home. Use a clean, separate machine to download any tools you need. Back up important personal data (documents, photos) only — do not copy executables or installer packages without scanning them first.

Gather a few quick diagnostics (run from an Administrator command prompt) so helpers can spot active connections and services:

netstat -ano
tasklist /svc
ipconfig /all

If processes or ports look suspicious, note the PID from netstat and match it in tasklist. If files or temp items cannot be deleted because the AV intercepts them, either temporarily stop the AV protection (use the product GUI to disable shields) or boot from trusted rescue media/USB and delete while offline.

Use specialised, non-destructive tools before manual deletion: Autoruns (to locate and disable persistent autostarts), Process Explorer (to identify handles locking files), and a reputable bootable rescue scanner to run offline scans. Run a rootkit detector as well — persistent backdoors sometimes hide via kernel hooks. After removing entries, reboot and re-run a full, up-to-date scan with at least two different engines (on- or offline).

Repair system settings that malware commonly changes: reset browser search/toolbars via the browser’s reset options, restore a clean hosts file and correct DNS entries, and check scheduled tasks and service entries for anything unfamiliar. After confirmed cleanup, change all online passwords from a clean device.

If removal still fails or the system integrity is in doubt, the safest course is a clean reinstall: image the drive for forensics if needed, copy critical user files (scan them on a different machine), then reinstall Windows and thoroughly update it before reconnecting.

Just to add as well, when I try to delete my temp internet files norton AV goes spastic telling me about the colfusion virus, and I cant delete the files...access denied

Try emptying the temp folders while in Safe Mode (you'll be going there in a bit anyway).

This is just a quick review because I know you've been waiting; I'm sure there is more, but I've gotta get some sleep.

Close all browser windows, scan with HJT, and have it fix the following entries:
R1 - HKCU\Software\Microsoft\Internet Explorer,SearchURL =
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar =
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page =
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,SearchAssistant =
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,CustomizeSearch = res://C:\PROGRA~1\Toolbar\toolbar.dll/sa
R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant =
R0 - HKCU\Software\Microsoft\Internet Explorer\Toolbar,LinksFolderName =
R3 - URLSearchHook: (no name) - - (no file)
F2 - REG:system.ini: Shell=Explorer.exe winsock.scr
O1 - Hosts: www.dcsresearch.com
O4 - HKLM\..\Run: [dxset.exe] C:\WINDOWS\dxsetu.exe

Reboot into Safe Mode

Go to:
C:\WINDOWS and delete dxsetu.exe
All Temp and Temporary Internet folders for all users and empty them.

Do a full system scan with NAV; let us know if it finds something it can't fix (and it's location)

Reboot normally, close all browser windows, scan with HJT, and post a new log please.
