Anti Virus Software
The anti-virus software market is extremely popular. There are 10+ large players in the industry and no one company really has a monopoly on the others. This is quite rare when it comes to computer software in general. There is normally always one major player but in the anti virus and virus scanning software market, there isn’t. With that said though, all of the virus protection applications that you can buy off the shelf at your local software store do pretty much exactly the same thing, they protect your computer from harmful computer viruses.
With this in mind, it doesn’t really matter so much which brand you buy. All that matters is that you buy one with a good virus definition database and more importantly, buy an application that offers free, daily updates. Computer viruses change vast with new ones being released daily, so you need to keep up to date. Some applications I have seen in the past charge you significant amounts to update your various patterns and definitions. This is something you need to look out for.
All virus prevention and scanning applications offer the basic service of identifying viruses within your system currently and also alert you should you try and open a file that contains a virus. Some of the more advanced and ultimately popular virus scanning applications such as BitDefender also contain malware, spyware and adware protection elements that take virus scanning a step further than the traditional sense by protecting you against online and web based threads. Some applications also feature anti-phishing tools in order to stop you giving out your personal data to those pretending to be someone else such as your bank for example.
