Long story but bear w/me..bought laptop fm BestBuy w/Norton included. Notified by BestBuy Norton no longer supported and sent me to Webroot where Anti-virus was downloaded and good till 9/4/2014. Geek squad will renew for $53+ but same protection is avail. fm Webroot for $40. No brainer... My question is this: As I already have the software anti-virus already downloaded, on 9/14/2014 do I tell Webroot I want to "renew" or do I have to uninstall and re-install the anti-virus?
