• What is viruses?
  • virus - (virology) ultramicroscopic infectious agent that replicates itself only within cells of living hosts; many are pathogenic; a piece of nucleic ...
  • virus - a harmful or corrupting agency; "bigotry is a virus that must not be allowed to spread"; "the virus of jealousy is latent in everyone"
  • virus - a software program capable of reproducing itself and usually capable of causing great harm to files or other programs on the same computer; "a true virus cannot spread to another computer without human assistance" 

  • What is antivirus softwares?
  • anti virus - A software utility that searches a hard disk for viruses and removes any that are found. Most antivirus programs include an auto-update feature that enables the program to download profiles of new viruses so that it can check for the new viruses as soon as they are discovered.

  • What is Spyware?
  • Installs and gathers information from a computer without permission, and reports the information to the creator of the software or to one or more third parties. It provides the consumer with little or no control over removing the software.
    Spyware can change system settings, install keystroke loggers, collect and report consumer's personal information, use computer processing capacity without permission, and deliver spam or ads without consumer's notice and consent.

  • What is Antyspyware software? 
  • Many programmers and some commercial firms have released products dedicated to remove or block spyware. Steve Gibson's OptOut pioneered a growing category. Programs such as Lavasoft's Ad-Aware SE (free scans for non-commercial users, must pay for other features) and Patrick Kolla's Spybot - Search & Destroy (all features free for non-commercial use) rapidly gained popularity as effective tools to remove, and in some cases intercept, spyware programs.

  • What is Malware?
  • "Malware" is short for 'malicious software' and is usually used as a catch-all term to refer to any software which causes damage to a single computer, server, or computer network. 

  • What is Antimalware software?

  • As malware attacks become more frequent, attention has begun to shift from viruses and spyware protection, to malware protection, and programs have been developed to specifically combat them.
    Anti-malware programs can combat malware in two ways:
    1. They can provide real time protection against the installation of malware software on a computer. This type of spyware protection works the same way as that of antivirus protection in that the anti-malware software scans all incoming network data for malware software and blocks any threats it comes across.
    2. Anti-malware software programs can be used solely for detection and removal of malware software that has already been installed onto a computer. This type of malware protection is normally much easier to use and more popular.[citation needed] This type of anti-malware software scans the contents of the windows registry, operating system files, and installed programs on a computer and will provide a list of any threats found, allowing the user to choose which files to delete or keep, or to compare this list to a list of known malware components, removing files that match.
    Real-time protection from malware works identically to real-time antivirus protection: the software scans disk files at download time, and blocks the activity of components known to represent malware. In some cases, it may also intercept attempts to install start-up items or to modify browser settings. Because many malware components are installed as a result of browser exploits or user error, using security software (some of which are anti-malware, though many are not) to "sandbox" browsers (essentially babysit the user and their browser) can also be effective in helping to restrict any damage done.
