I have tried NOD32 and like it. I want to buy it. I am fixing to wipe my hard drive and do a fresh install of the OS. My question is, can I install the trial and buy thru it, or do I have to download a different NOD32 if I bought it. The reason I want to know is because I don't want to install the trial if I have to turn around and uninstall it. Especially on a clean install of OS. Thank you for your input.
