Download Microsoft Security Essentials For Free Anti-Virus Protection.

Modern, up-to-date browser software helps protect you against online problems.

You use a web browser to look at websites. It's the doorway to the internet. Examples include Microsoft Internet Explorer, Google Chrome, Apple Safarior the software that is showing you this page now is your current web browser.
Just like any other software, it makes sense to use the latest, most secure web browser. The latest browsers have security features that block fake websites and protect against some viruses (but you still need anti-virus for advanced protection).
If you have updated your computer regularly or bought it in the last couple of years, it is likely that you are already using an up-to-date browser such as Microsoft Internet Explorer 8 (on Windows PCs) or Safari 5 (on Macs). You can check by selecting 'About' on the browser menu. If this is not the case, you may want to get the new browser software immediately and update it regularly for maximum protection.
Anti-virus software protects you, your privacy and your money. Viruses are not good for the computers. They steal personal information, take over your PC, pop up unwanted adverts and they can even use your computer to attack other people's computers. You may also hear them called malware, trojans, spyware or adware. Anti-virus software protects you against all of them. To work properly, anti-virus software has to download updates regularly over the internet. Out-of-date anti-virus software will have flaws. It is a good idea that you install anti-virus software if you don't have any already.
You can download Microsoft Security Essentials (free for personal use) or a renowned antivirus such as McAfee.
