IMPORTANT information for Microsoft Security Essentials/Defender Anti-Virus users:
Over recent years there has been much debate about the effectiveness of Microsoft’s free antivirus package, Security Essentials, or Windows 8 Defender. Until recently Microsoft have defended their corner but this has now changed. Holly Stewart, senior program manager of the Microsoft Malware Protection Centre recently explained that the company had stopped improving its antivirus solution almost two years and chose to work with other companies on identifying threats.
So what does this mean to you?
In short, if you are relying on Security Essentials (XP, Vista, Win 7) or Defender (Win 8) then you are NOT adequately protected. My advice is to remove the Microsoft protection and install a recognised third party anti virus.
Which solution should I install to replace Security Essentials?
There are lots. If you want to use a reliable free anti-virus then go for AVG or Avast. If you would like additional protection and want to pay for a more in depth security package then I would go for Norton, Kaspersky or Bitdefender. I regularly check various antivirus surveys and these three tend to be in the top five consistently.
