What is anti-virus software? Anti-virus software consists of programs designed to detect the presence or occurrence of a computer virus. If any virulent infections are found on your computer, you can set the anti-virus program to quarantine or delete the infection. Why is anti-virus software required? Malware (malicious software which includes viruses, adware, spyware, Trojans, keyloggers and other destructive programs) is now widespread on many people's computers. Recent estimates state that about 70% of computers which connect regularly to the internet are infected with some kind of malware. In many cases, the infection results in simply a slow-down of the computer's functionality, but malware can also be extremely destructive, deleting files and interfering with operating system functionality, and in the case of spyware/adware, sending personal information such as credit card numbers and bank account details and access codes to a criminal third party. http://www.antivirusroot.com/antivirus
