I recently had reason to update my Adobe Shockwave Player and when installing it asked whether I would like to install a Free Norton Security Scan.
My strong advise is , with all these additions to downloads that you can be offered , is to say NO.
Do not put the tick in that box.
There are many online virus scanners that will not intrude on your system and to install one with another piece of software is fraught with danger.
Now for toolbars
I have seen many systems with multiple toolbars installed on them , some examples are:
- My Search
- Windows Live
- Ask Jeeves
My strong advice is don't install these toolbars , they will slow your system down and some toolbars are linked with rootkits and spyware ( not the one's listed above )
