First of all we have to remove Newdotnet, either from add/remove programs, or by going here. & scrolling down to the uninstall tool.

Unzip HJT into it's own permanent folder before doing anything in order for it to create backups. (Not a temporary folder or directly on the desktop & not directly on your hard drive). Close all (browser) windows & rescan with hijackthis. When the scan is finished place a check in the box to the left of the following entries & click 'fix checked' :

O4 - HKLM\..\Run: [bxwbjg] C:\WINNT\system32\mrlugh.exe
O4 - HKLM\..\Run: [alchem] C:\WINNT\alchem.exe

Reboot into safe mode following the instructions here & navigate to & delete the following if found:

C:\WINNT\system32\mrlugh.exe< file
C:\WINNT\alchem.exe< file

Reboot normally.
The 017 entries take me to a yellow pages site. Seems a bit suss to me. If this is from your ISP or company network then leave them, otherwise fix them with HJT.
