I currently have Kaspersky Internet Security 2012 (had 2011 last year). I have 5 days remaining for my paid subscription. I am debating in purchasing Kaspersky Internet Security again ($27.99 through amazon and can get for around $12 through Ebay). I also received from my brother an unused ESET NOD32 Antivirus 4. So, it is free for me. 1) First of all since the disk I have is ESET NOD32 4. With the license number will I beable to receive ESET NOD32 5 for free since the license has not been used yet? 2) I know on Kaspersky if I type something on a search engine (lets just say google) Kaspersky has a green "K" next to confirmed safe websites. Does ESET have something of that sort that indicates a confirmed safe website? 3) From what I gathered through research it seems that ESET is less of a resource hog, BUT, from what I also read is that Kaspersky is overall a better protection software than ESET. So, what kind of loss of protection will I incur if I use the free ESET NOD32 that my brother gave me in comparison to the Kaspersky Internet Security that I am used to?
