Even some viruses may affect hardware of your computer. Many people are thinking only internet users requires Anti Virus but the truth is that Anti Virus is important for every Windows PC user because you PC can be affected by removable media also(Pen drives,Hard disk etc.,)
Independent test lab AV-Test has completed a series of tests for antivirus/anti-malware products on Windows 8 and 8.1.
They compared both business and consumer solutions. For each, they tested with the then-current version last November and December to increase confidence in the numbers. They compared the business solutions to Microsoft System Center Endpoint Protection and the consumer solutions to Microsoft Windows Defender.
For each, AV-Test generated scores for protection, performance and usability. Each score ranges from 0 to 6 and are added to make the Total score.
Protection is defined by how well they blocked known and unknown malware. Products with a score of 6 blocked 100 percent of malware or very close to it. Performance is a measure of the product’s impact on the system speed, but AV-Test provides no details on how the numbers were calculated. Usability is a function of the number of false positive detections in various situations; “Usability” is perhaps not the right word for it, but it’s a valuable metric nevertheless.
The stand-out business products are from Bitdefender, Trend Micro and Kaspersky, with F-Secure not far behind. Bitdefender did not received a 100% score for detection, but it was very close. Trend Micro, Kaspersky and F-Secure fell short in system performance impact, but not by much.
