I love manually getting rid of these, it used to take up most of my Holiday in South Africa cause they were too daft to know what was causing so much bother.
If you know the names there will certainly be a removal tool on the net.
If its prohibiting your net connection from functioing properlly, go into the task manager and kill the exe files, then try.
If you can find the source folder, they always shift around, but find the source and rename the exe in the folder to anything.txt (this is after you kill the exe in task manger or you will get file in use error)
Theres more to this and its very long winded but at least this will help you get the removal tool to work effectively.
Happy times
