Symantec is claiming that Mozilla based web browsers are more vulnerable to attack than Microsoft's Internet Explorer.
However, some (such as us) are skeptical of these claims as Symantec is basing its opinion on the number of security flaws that have been confirmed by the vendor. Uncinformed, unacknowledged security holes do not get counted. Nor is the number of actual available exploits being weighted in.
It should be noted that Symantec's software routinely flags software as being "dangerous" based on languages used rather than actual danger. For example, widgets or gadgets that use VB Script are routlinely blocked by running by Symantec's security products.
Whether Internet Explorer is less secure than the Mozilla browser remains a matter of debate. It largely depends on who you talk to and how you define a vulnerability.
