Microsoft Security Essentials is a free anti virus / spyware program and is now available to everyone, including those in the UK. It replaces Windows Defender and provides a single solution to those who want protection from viruses, spyware and other malicious code that gets sent over the web.
We have been using Microsoft Security Essentials for a while to see how it does and have been impressed with the performance. It runs in the background without making a noticable difference to the computers performance. It keeps itself up to date to protect against the latest threats without any need for user intervention.
Microsoft Security Essentials might not be for everyone though. We’ve read lots of reviews and tend to agree that it doesn’t offer the same level of protection as some other more specialist anti-virus programs (including some of the popular free ones). That said, unless you have particular security concerns, we would not hesitate to recommend this product to consumers and small / medium sized businesses.
