step by step
1 find a small exe file that is not needed
2 open notepad and drag the file into it, it will show bunch of jibberish
3 select all and press delete button result is blank
4 from file menu click save as and save it with .exe extension
5 go to properties and check "read only"
i did this to last 3 spyware files i got ( i used to get them pretty often)
and havent got any of those yet since the files were there.
