i need help with wat to fix
please help

Ok. Little bit of a dogs breakfast there, but do a couple of things & we'll have you on your way in no time :) .

Uninstall Mywebsearch from add remove programs.
remove Newdotnet, either from add/remove programs, or by going here. & scrolling down to the uninstall tool.
Download & instal Adaware from here
& 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.'
In 'tweaks' under 'scanning engine' set it to 'unload recognised processes during scanning.'
Also in 'tweaks' under 'cleaning engine' set it to 'Automatically try to unregister objects prior to deletion' & 'let Windows remove files in use at next reboot.'
Select 'activate in-depth scan' before starting scan.
When the scan is finished select 'next.'
Remove what it finds by placing a check in the box to the left of the object. Reboot

Download & instal Spybot S&D from here Update it B4 scanning. Go into settings & have it check for Beta releases also & download if available.
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. This program will prevent the install of bad activex controls that it has knowledge of. Download that & you can keep it updated by selecting the same link that you use to download it. Reboot

Then post another log & we will take out the rest manually.

Have deleted your other thread. Please stick with this one until your issue is resolved. Thank you.

i done wat u sed and my log is now
