Computer viruses can affect almost any computer, and unless you are protected in advance you would be in a lot of problems. There are now a number of commercial software tools, but if you want only for home use, there are a number of PC virus removal free tools available that you can consider.
Most of these is for versions of feature limited counterparts trade to obtain the same scanning and binding engine.
To begin with there is AVG Free. It is one of the best free anti virus tools out there because it is easily the lightest anti system virus happens ever through. In fact, even if you run an age of the stone PC with processor Pentium 3, Windows 2000, 128 MB RAM, this anti virus be completely unnoticed and at the same time totally effective. AVG also comes with a built anti spyware tool. He is also very reliable because it is updated at least once a day automatically.
Another option is Avast Home Edition. It is free for home users and people who use computers for personal use. The main thing you will notice with Avast is that the interface of this software may be stripped. Now why anyone in the skin an anti virus is that one thing too complicated to understand. But when it comes to its actual work, Avast is excellent. It is really good and its VRDB functionality is something which makes the tool really stand out the crowd.
Avast is not resource intensive can be easily run on any PC purchased in the last 5 years or more. It also comes with an integrated anti spyware module. This allows you to save the need for a separate anti spyware tool on your PC. Avast is completely free, but there is an annual nag her. You must provide a valid email ID to get the free updates once in a year. There is no charge, but to do so once in a year may be tolerable or annoying depending upon your choice.
Your third option is MoonSecure Antivirus. Less well known that the two previous options, it is still a competitor. Apart from its tag line that said "Security of space", it is a tool antiviru really down to earth. The main thing is that it is free software and open source. This means that the source code of the program is available to anyone who wants. It can also be used in a commercial facility. The software can be downloaded in the form of the source, and you can make changes in the code so that they meet your requirements.
MoonSecure uses the same core engines which power the property known ClamAV and ClamWin, but he is able to do the analysis in real time which is absent in the family of clam antivirus solutions.
Free PC virus removal tools are available for the Microsoft Windows platform in most cases, although Clam AV is available for Unix based and systems.
Conclusion - Yes you can protect your PC with free software. It really depends on the level of security that you need. Personally, I am launching a package of anti-virus subscription paying on my system, but I also have a free that use to run next to this package.
The reason is that well-known brands are heavily targeted by virus for a lesser aswell suite known running programmers must catch all malware that slips the net.
