the newdot thing but it took me about 10mins to rid it
runs msconfig.exe—stop any bodgy start ups and disable any wierd services,if you dont know what is good to keep running and what is not,nows a time to learn.
run bootscan,it will prohably detect a few infected files–delete them
run a reg vac i have regvac and reg seek,also have hijackthis
always empty your tempinternetfiles,check program files for wierd progs,you will prohably find one in there called newdotnet.
check your startup folders,run the reg vacs,these often delete unassociated links and suspect enrties
go to the registry manual edit delete anything that says newdot net,run the regvacs again,check task manager for runnign apps .
do another boot scan,no of infected files =0…okay
boot up,do reg vac run hijack this
dlete ant newdot net folders or any wierd progs in program files or installed program files in windows.check start up folders and any folder in documents and settings that yuo think might hold a prog
run the reg vac ect
i keep doing this until i have disabled the virus startup association keys and files and services
keep doing this
till its gone
if it persists,its hanging off somthing,then yuo might have to do manual regedit again .
Hint,when it infected my computer there was a newdotnet folder in my program files that kept rewriting
Hint set you page file to clear on exit—its a reg edit
hint–learn how to tweak your internet seetings
for security and how to make small edits in the registry that can make a large difference.
cheers
just an edit,i almost forgot,while doing all this dissconnect yuor machine from the internet 
and also file shredders are great for those stubborn files .
i also have Kerio firewall it alerts yuo when anything is on the move locally,neat
and vision will alert yuo with registry changes on the move
both software allow you to deny changes and continue,…with what your doing ,great stuff ;D
Avast resident security set to high.
