Start with downloading Spybot and Ad-aware from links in my signature. Install, immediately update and run. Delete all they find. Also download and run CWShredder. Then post a new log. You seem to have omitted some important information from the top of your log. Please include it with the next.

 

Check i addremove progam and uninstall any fun web programs, if they are there.
FunWebProducts 'My Search Bar' 'MyWay Speed Bar' "Myway toolbar" MyWebSearch, anything Myway.

then make and post a new log , include the entire log though please.
And do mention any problems you may be having.
