Freeware Antivirus for Windows® 7
Antivirus software provides an essential layer of protection from a multitude of virus, Trojan, worm, spyware, adware, dialer, key logger and rootkit infections in your Windows 7 Operating System. Most of the antivirus programs that are currently available have good detection rates for all forms of malware. Malware includes viruses, Trojans, worms, spyware, adware, dialers, key loggers and rootkit threats that carry out malicious activities on a computer. With the vast increase in malware, antivirus software cannot continue detecting all of it. But using more than one real-time detection, antivirus reduces protection of your Windows 7 Operating System in your PC.
The main freeware antivirus software for Windows 7 Operating System are:
- avast! free antivirus

avast! Free Antivirus is an excellent free antivirus that is used by many users.

Microsoft Security Essentials
Microsoft Security Essentials is the personal favorite of many Windows 7 users due to the good detection rates, particularly for rootkits. Even more notable is that Microsoft Security Essentials has very few false positives, is light on resources and is good at removal of malware that exists. Microsoft Security Essentials is one of the best choices for average users because of the minimal user interaction that it requires. It automatically updates and eliminates threats. No registration is required, apart from a rapid validating of Windows, and there are no advertisements that irritate you while working.
