avast Antivirus 6
First, lets take a look at the free offering from AVAST Software for home users: avast Antivirus 6. It includes virus, spyware, and rootkit protection. In addition to the basic functionality, here are some of the advanced features youll find:
Real-time shields: The file system shield monitors and scans files you open, save, and store on the computer. It serves as the main component of protection and is similar to other real-time scanners. However, avast also provides additional shields that monitor specific connections to potentially detect infections before they actually get to the file system. These shields monitor mail, Web, P2P, IM, and network traffic. The script and behavior shields also provide detection of scripts and suspicious behavior.
Boot-time scanner: Can be enabled to run a scan before Windows loads the next time you reboot. Since it has direct drive access, it may be able to better remove rootkits and other stubborn infections. Site blocking: Optionally list URLs to block users from visiting. Though only a basic filter, its a great bonus feature.
Virus alerts: Can notify others of any viruses that are detected, sent via email, printer, or network message.
Password protection: Protect the avast components and settings with a password, so your children and others cant play with or disable it.
No matter which antivirus solution you use, its best to run weekly full scans to make sure no infections have made it through. Some antivirus programs auto schedule this for you, but avast doesnt. But dont fret, simply click Scan Computer, click More Details for Full System Scan, click Settings, and select the Scheduling tab.

Comodo Internet Security 5.3
The Comodo Internet Security suite offers free protection for both homes and businesses. In addition to virus, spyware, rootkit, and bot protection, it comes with a firewall. It also has even more advanced features, including:
Auto and manual sandboxing: Untrusted executable files and programs are automatically ran in the virtual environment so modifications cant be made to the real system. This is similar to avast, but Comodo lets you manually run programs in the sandbox at your choosing. You can also view and manage the trusted and unrecognized files.
Web filtering: This DNS-based service helps to block known dangerous websites at the browser before you have any chance of becoming infected. But if you want to block specific sites or categories, youll have to use a different solution such as OpenDNS.
Advanced customizable polices: Comodo is highly customizable with advanced settings. You can create a computer security policy as a part of the Defense+ component and a network security policy for the firewall.
Configuration management: Maintain, save and export multiple configurations of your settings. Great for backup purposes or for deploying multiple computers.
Password protection: Protect components and settings with a password to prevent children, employees, or others from changing settings or disabling protection. Optionally suppress alerts to prevent users from doing damage, such as ignoring a virus.
Currently, Comodo is offering a 60-day free trial of GeekBuddy, a live remote PC support service. When you install Comodo Internet Security you can choose to also install their remote software that you can use to request assistance.
I should point out that rootkit scanning isnt enabled by default in Comodo Internet Security. The vendor said this is because it may create false positives that cant be distinguished by average users. However, if you think youre able to, you should enable it.
AVG Antivirus Free Edition 2011
The AVG Antivirus Free Edition 2011 provides protection for home users against viruses, spyware, and rootkits. Its security functionality is fairly basic compared to the previous two solutions. Though there are a few notable features:
Link scanner: Displays safety ratings of links in search results to help you identify dangerous sites before you visit them. This is similar to what other antivirus solutions (such as avast) provide.
Desktop gadget: Optional small gadget that remains on the desktop of Windows. You can check the status of AVG, start a scan, and check for updates. There are also shortcuts for Facebook, Twitter, and a search box to use the AVG search engine. But keep in mind, the search box cant use other providers, like Google.
Browser toolbar: Shows the safety rating for the current website youre on. Youll also find an AVG search box and shortcuts to news and weather. It also has an email and Facebook notification feature that could be useful.
PC analyzer: Scans for Windows registry issues, junk files, drive fragmentation, and broken shortcuts, all of which can cause performance issues. But the annoying part is that have to download another utility to fix any found issues. Plus you can only run one free fix then you must purchase it.
Remember, AVG Antivirus Free Edition does not provide sandboxing. If something bad does slip by, it has a much better chance of causing damage. Additionally, it doesnt provide password protection in case you have children or other curious users.
Like avast, AVG doesnt automatically set a weekly scheduled scan. So make sure you do it yourself.
Microsoft Security Essentials
Microsoft now provides an antivirus solution: Microsoft Security Essentials. Its free for home use and for businesses on up to 10 PCs. It includes protection for viruses, spyware, rootkits, and other malware. Its security functionalities are also pretty basic compared to the avast and Comodo solutions we discussed earlier. Though there are two noteworthy features:
Network inspection system: Detects malware infections coming from network and Internet connections before they hit your computer. Behavior monitoring: Identifies and stops suspicious activity or patterns that could be dangerous.
Remember, Microsoft Security Essentials is a very basic solution. Even the two features above lack any logs or settings. Like AVG Antivirus Free Edition, it also doesnt have sandboxing or password protection.
In my review, I found avast Antivirus 6 and Comodo Internet Security 5.3 provide more security features than AVG Antivirus Free Edition 2011 and Microsoft Security Essentials.
Bear in mind, the actual detection and repair performance of each varies, which we didnt get into. For benchmark testing, check out AV-Comparatives, Proactive Security Challenge, Virus Bulletin, or AV-Test. Consider their testing methodology and all features of the product to determine which you think is the most secure and best fit for your home or business.
If your computer is for business use, youre limited to using either Comodo Internet Security with advanced features or Microsoft Security Essentials with basic features. If you have any untrusted users, use a solution with password protection like avast or Comodo.
For the free antivirus programs that dont include a firewall, using just the Windows Firewall in XP and later typically provides enough security. Otherwise, consider a free third-party firewall, such as from Comodo or ZoneAlarm.
Most free solutions also lack SPAM filtering, but many email providers and client applications provide some type of filtering. If not, consider free solutions such as Comodo AntiSpam, Spam Pal, or SpamBytes.
