When it comes to naming Windows anti-virus vendors, is Microsoft's Security Essentials one of the vendors on the tip of your tongue? Well, it should be, at least according to OPSWAT, the anti-virus tools vendor. In their last market share report released this week, their share rose to nearly 15% of the North American market, making it the top single product. Symantec owns more market share as a vendor but spread across several different product lines.

The corporate Internet is a very different place these days, at least according to research done by cloud security vendor Zscaler's research arm ThreatLabZ. The report analyzes billions of Web transactions over Q4 2011. In particular, Facebook, Blackberry and Internet Explorer continue to decline in terms of enterprise traffic seen last year. The biggest threat to corporate security is outdated browser plug-ins, such as Acrobat and Flash, providing "a key driver for threats in the wild," according to the authors.

At the end of every year, AV-Comparatives releases a summary report to comment on the various anti- virus products it has tested over the year, and to review their high-scoring products too. This year, the top overall award goes to Kaspersky Anti-Virus. Anti-virus tools from Avira, Bitdefender, ESET and F-Secure were also highly rated. We last wrote about their 2010 test results here where F-Secure won the top berth.
