Windows says my computer isn’t secure so what to do

Windows - Windows 7/ XP

Problem in details : Microsoft has given Windows built-in security alerts that flag if your computer isn’t protected by antivirus software. This triggers a pop-up alert originating in the system tray.

Solution : Open the Windows Action Center, which can be found in the Control Panel. This will tell you what is causing the security alert to show up. In most cases, the problem is a lack of anti-malware software on your PC. This problem can easily be solved by downloading Microsoft Security Essentials (Link). This is Microsoft’s free anti-malware application, and it has received favorable reviews. Alternatively, you can download a free third-party anti-malware app or you can purchase an Internet Security suite from a company like Norton or McAfee ( but try to solve without using third-party anti-malware app )
