AV Software

Antivirus software is a tool programed to prevent, detect, and remove computer viruses such as Spyware, Trojan Horses, Worms, Adware, Bots and Botnets, DDOS Attacks, and Fake AV. In its simplest form, antivirus software scans suspicious files and searches for known viruses. Other kinds of AV software are always active, attempting to detect the actions of general classes of malware. AV software must be regularly updated so it can keep up with the latest viruses as they are released1.

There is a great variety of strategies employed by antivirus software vendors. The traditional approach, known as signature-based detection, involves searching for known patterns of data within executable code. However, it is possible for a computer to be infected with new malware for which no signature is yet known resulting in a zero-day exploit. So more advanced antivirus software solutions will include technologies that can identify new viruses or variants of existing viruses by looking, for example, for slight variations of known malicious code, and predicting what a file may do2. The more extensive the vendor’s email, web, and file reputation databases, as well as how well they correlate the threat information in them, the greater their ability to recognize and block code variants.

You may be concerned that antivirus software will slow down the performance of your computer. Products with cloud-based detection and protection technology – such as Trend Micro Security, Worry-Free Business Security, and OfficeScan endpoint security – run with minimal performance impact on your systems.

The dangers that plague computers without antivirus software are not going away, so understanding threats and their impact is crucially important. Ever since computer systems and networks were introduced, various types of cybercriminals have existed to breach security. The organization and skills of these cybercriminals pose ever-changing, highly sophisticated treats. Because of this, traditional antivirus software is not a cure-all. Using a reputation-based solution helps protect you from the diversity of the threat landscape by blocking threats at their source, before they reach your computer. The Trend Micro™ Smart Protection Network™ infrastructure correlates 16+ billion web, email, and file queries daily to block 200 million threats each day. This cloud-based infrastructure and its fine-tuned data mining tools identify and stop new threats faster, allowing Trend Micro to deliver on its mission to make the world safe for the exchange of digital information.
