Truth is, all systems need an antivirus software. Most computers these days come with one installed yet it often has limited features. Experts claim that antivirus programs are only effective or reliable as their virus signature databases. What is generally involved? Since it’s impossible to catch each new virus that crops up, most antivirus companies share info and collaborate with one another. For instance, when a particular company discovers a new type of virus, it goes to a pool of data that is essentially shared with other firms, thus increasing the chance to detect and eliminate the malware in the process.
Since no antivirus program works to capture all viruses at all times, it’s best to run two at a time. For an affordable and solid option, you can go online and get free online virus scanners such as the Panda’s Active Scan or the BitDefender to help detect what’s wrong with you computer system. For other open-source programs that are available out there, you can choose between Clam Antivirus and the Open Antivirus Project as well as the commercial ones including AntiVir, AVG and Avast Antivirus. In most cases, the best antivirus program is merely one that you find most convenient and simple to use. Case in point, the Avast Free Antivirus is considered by most people as the top pick at present. Why is that? Mainly because of its higher rate in detecting new malwares. The software also has full real time features such as network, web and email protection along with scrip blocking and the like.
Basically, scanning your system with two free antivirus programs is a surefire way to highly protect your PC, at no added cost. After all, it’s not your fault that malwares tend to attack your system or anyone for that matter so why should you invest additional dollars for it?
