Microsoft have just announced that Microsoft Security Essentials (MSE), their free anti-malware software, will be released as a beta on Tuesday 23rd of June.

According to Microsoft, the produce will protect against viruses, spyware, rootkits and trojans, and will use little by the way of system resources.

Many consumers and businesses alike are delighted by the news, and hope to be able to ditch their existing applications when the next billing cycle is due. But companies like AVG, Kaspersky and Symantec are probably less than delighted.

If the product turns out to be little more than a basic, less than reliable freebie, then it won’t ripple the market.

If, however, it proves to be effective, then we may all be in trouble.

Customers benefit from competition. The main reason for the high quality of the existing solutions is that they’re all fighting for customers.

If Microsoft’s product turns out to be a roaring success, it may seriously maim some of the long-standing names in the industry.

Even the strongest and most robust of industries may be reduced to a fragile ecosystem when a new giant goes blundering in.

On the other hand, the new product may serve as new competition, inspiring the existing antivirus companies to get that little more serious.

Light a fire under an industry, and the main players get active. Allow the fire to spread and everything may be destroyed.
