This anti-virus product is an effective product, but not as good as Kaspersky. It is a product that is easy to install and use. It's a step above its previous version as the 2009 version offers real-time, scheduled, and on-demand scanning options. The NAV 2010 version offers new features that will reduce the task in scanning and removing of malware, as well as improves protection against the latest viruses, spyware, and more at a price of only $39.99 (at symantec.com).
NAV 2010 improvements include:
- Faster protection
- Quick, full and custom scan
New features: it includes Norton File Insight, Download Insight, System Insight, Threat Insight, Insight Network, and SONAR 2.
What's new: Norton AntiVirus 2011. It includes features specifically engineered to catch the most lethal viruses (the ones that aren’t found by traditional security signatures), as pointed out in the Norton AntiVirus Review by TopTenReviews.
Highlights: Norton is well-known for offering real-time virus protection: providing proactive performance warnings. Its program may be a good choice for those users who seek not only virus protection, but quick installation too.
Its anti-virus products are said by consumers to be better than Norton's. The new Kaspersky Anti-Virus for 2012 offers cloud technology: featuring a dual cloud-and-local security system interface. This new function, launching a cloud-based detection network, only costs $59.95 to buy.
Version history: The 2009 version provides up-to-date protection, and protects users from Phishing and Malware sites. It offers real-time automated protection against current Internet threats. Additionally, it provides real-time scanning of e-mails. Simply said, with the 2009 anti-virus product alone, you are able to get complete antivirus protection from viruses and spyware, as well as from infected Websites.
It even got better with the extra tools and features in their KAV 2010 version. KAV 2010 provides essential PC protection (in fully automated real-time) at a price of only $39.95 (at kaspersky.com). KAV 2010 improvements include: Basic identity theft protection and blocking of suspicious programs based on their behavior. It also offers color-coding of links to unsafe websites.
When it comes down to which product is better, Kaspersky's 2011 Antivirus wins (according to consumer opions and by testing labs). Antivirus labs rank it at or near the top. Kaspersky just offers more features and protection than Norton, but costs a bit more too. Even though it's really up to the computer user and buyer to decide what product suits them best for the price, isn't the price worth the amount of protection to safeguard a PC?
Highlights: KAV 2011 turned out to be a top-notch anti-virus product and the new features in the 2012 edition just goes to show why Kaspersky is among the best providers of anti-virus protection.
