[phillyman2004]

I fix computers for customers everyday , and i have found ways to make the following Antispyware Programs Run without installing on the users machine

Spybot S&D

Spysweeper

Ad-Aware

I would like to get Microsoft Antispy to run without installing , I keep getting errrors each time i try though , This is the code for the others to run without installing (Spybot S&d Code) , I am not sure why i cant get it to run properly , The code below is for Spybot , and it works just fine
