Security risk includes viruses, malware, spyware, and grayware. Trend Micro Security protects computers from security risks by scanning files and then performing a specific action for each security risk detected.
Viruses and Malware
Tens of thousands of viruses and malware exist, with more being created each day. Computer viruses today can cause a great amount of damage by exploiting vulnerabilities in corporate networks, email systems and Web sites.
Trend Micro Security protects computers from the following virus/malware types:
Joke program: A virus-like program that often manipulates the appearance of things on a computer monitor
Trojan horse: An executable program that does not replicate but instead resides on systems to perform malicious acts, such as opening ports for hackers to enter. A Trojan program often uses ports to gain access to computers. An application that claims to rid your computer of viruses when it actually introduces viruses onto your computer is an example of a Trojan program. Traditional antivirus solutions can detect and remove viruses but not Trojans, especially those already running on the system.
Virus: A program that replicates. To do so, the virus needs to attach itself to other program files and execute whenever the host program executes.
Boot sector virus: A virus that infects the boot sector of a partition or a disk
Java malicious code: Operating system-independent virus code written or embedded in Java™
Macro virus: A virus encoded as an application macro and often included in a document
VBScript, JavaScript or HTML virus: A virus that resides on Web pages and downloaded through a browser
Worm: A self-contained program or set of programs able to spread functional copies of itself or its segments to other computer systems, often through email
Test virus: An inert file that acts like a real virus and is detectable by virus-scanning software. Use test viruses, such as the EICAR test script, to verify that your antivirus installation scans properly.
Packer: A compressed and/or encrypted Windows™ or Linux™ executable program, often a Trojan horse program. Compressing executables makes packer more difficult for antivirus products to detect.
Probable virus/malware: Suspicious files that have some of the characteristics of virus/malware. For details about probable virus/malware, see the Trend Micro Virus Encyclopedia.
Spyware and Grayware
Spyware and grayware refer to applications or files not classified as viruses or malware, but can still negatively affect the performance of the computers on the network. Spyware and grayware introduce significant security, confidentiality, and legal risks to an organization. Spyware/Grayware often performs a variety of undesired and threatening actions such as irritating users with pop-up windows, logging user keystrokes, and exposing computer vulnerabilities to attack.
Trend Micro Security protects computers from the following spyware/grayware types:
Spyware: Gathers data, such as account user names, passwords, credit card numbers, and other confidential information, and transmits it to third parties.
Adware: Displays advertisements and gathers data, such as Web surfing preferences, used for targeting future advertising at the user.
Dialer: Changes client Internet settings and can force a computer to dial pre-configured phone numbers through a modem. These are often pay-per-call or international numbers that can result in a significant expense for an organization.
Hacking tool: Helps hackers enter a computer.
Remote access tool: Helps hackers remotely access and control a computer.
Password cracking application: Helps decipher account user names and passwords.
