If you only have problems with the start page and pop ups
try this quick fix for param32.dll and see if that stops
it.
Create a folder on the desktop or c/drive.Right click a
empty space and choose New > Then Folder > Name it and
save both of these into the new folder
Download Killbox :

Download Hijack This :
http://www.spywareinfo.com/~merijn/files/hijackthis.zip
double-click on Killbox.exe
When it is open's enter
c:\windows\system32\param32.dll
into the field labeled Full path of file to delete.
Select the Delete on reboot option.
Then press the button that looks like a red circle with a
white X in it. Let it reboot.
When your computer has rebooted use hijack this,Choose to
run a system scan and save the logfile.Put a checkmark
next to the following entry:
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start
Page = http:://
www.newgenlook.info/ad/ad0034/
or any other R0 or R1 entries that show newgenlook,
Once those entries are checked, close any other open
windows except Hijack This & press the Fix button.
Exit HijackThis.
Run Ccleaner and remove anything found.Then reset web
settings (Open a Internet window and goto tools on the
top bar,Then Internet Options,Goto the programs tab and
press 'Reset Web Settings'
This could remove the problem for you depending on how
much crap has installed, still run a couple of virus
scanners though to be sure its clean.
Good Luck
