1. 0websearch has been set as the start page. 2. I change the start page to about:blank, it changes back to 0websearch after a while. 3. I can't open txt files with notepad any longer. 4. When I hit CTRL + ALT + DEL, I see "Services" running on the bottom. 5. When I shut down "Services" and run Notepad or try to open a txt file, "Services" runs again.
