When I boot up,I get this as my default page in Internet Options:
http://%76%70%75%7A%65%65%2E%74%2E%6...0?%61%69%64=35

The page eventually loads as :
http://th.msie.cc/index.php?aid=20035

On running hijack this,the file looks as follows:

Can you help,please,it's driving me nuts )

Many thanks to you all for a great forum.

it sounds like somobody or something has edited your system's HOSTS file to redirect your defualt page (homepage right?) or a specific url to another website.

go to C:\WINDOWS\system32\drivers\etc and open up the file called HOSTS in notepad. All you should see is a comment header and a single line with 127.0.0.1 localhost incase it dosn't, erase everything and enter the line below into your HOSTS file and save.

clean hosts file for you:

Have only HJT running & fix these entries=
