Hello,
I want to test the AVG anitvirus free edition, before downloading I wanted to know if:

it is also an antispyware and adware? or only Antivirus?
And if before downloading, i have to uninstall first my Norton antivirus and my Antispyware, or if I cna download it and test it, even if I still have my antispyware and antivirus already?

If you can reply to these two questions it would be very appreciated
Thank you so much in advance
Lena
