Another positive review of Security Essentials
The new, free Microsoft Security Essentials (microsoft.com/securityessentials) doesn't follow that pattern. This download for Windows XP, Vista and 7 seems downright meek: You don't have to click past upsells for a premium edition when you install it, and your only hint of its existence afterward may be two icons at the corners of the desktop.
Combined with Windows' built-in firewall and the automatic blocking of hostile Web sites provided by such modern browsers as Firefox and Microsoft's Internet Explorer 8, Security Essentials can do a lot to keep a PC safe — and without the irritation factor of many competing programs.
But it can't do it all. The most effective security measure — on Windows or in any other operating system — remains a cautious, skeptical person between the chair and the keyboard.
