You have a heap of crap there, but 1st off you MUST get rid of Newdotnet.
Newdotnet removal instructions here http://www.newdotnet.com/#remove
Then We will get you to do the following which will clean up a lot more stuff B4 we remove what is left manually using HijackThis.
Download & instal Adaware from http://majorgeeks.com/download.php?det=506
& update it B4 scanning.
In settings under 'scanning,' have it set to
'scan within archives,'
'scan active processes,'
'scan registry,'
'deepscan registry'
'scan my IE Favourites for banned URL's,'
'scan my host's file.'
Also in tweaks under 'cleaning engine' set it to 'Automatically try to unregister objects prior to deletion.'
Remove what it finds by placing a check in the box to the left of the object.
Download & instal Spybot S&D from http://www.safer-networking.org/index.php?page=download Update it B4 scanning.
After the scan is complete, have spybot fix everything marked RED.
On the page that first opens when you start Spybot there is an option to immunise, you should do this. In the immunise section there is also a link to download Spywareblaster. Download that & you can keep it updated by selecting the same link that you use to download it.
Please post new log after rebooting.
