ActiveX is just a way of extending the functionality of a web browser, but it's also the way most spyware manages to get a foothold in your system. Just take my word for it unless you want a long technical explanation.
The security risks posed by ActiveX are just one of numerous reasons why I tell people to avoid IE like the plague. If you haven't been infested with spyware yet, count your blessings and start using Firefox or Opera immediately. Otherwise, clean up the spyware, then start using Firefox or Opera immediately following.
I have a question...Is Active X spyware/adware and if I download it is it an open door for these. Is it a safe download to use for msn ect.
