[All anti-virus scanners run on startup as soon as the scanner is successfully installed.|Every anti-virus scanner runs upon computer boot up as long as the software has been installed successfully|When antivirus software is successfully installed, it automatically runs upon startup.] [It is necessary for these software to run in the background in order to scan for viruses when there are new files coming in and out of the system.|It is an important requirement for these antivirus software to automatically run in the background to detect incoming and outgoing files in the system.|These software should really run a scan even in the background to check the system for possible malicious activities.] [This is commonly referred to as "Real-time Protection" and serves as a first layer of security in virus prevention.|It is what we called "Real-time Protection" that acts as the first layer of security to prevent incoming viruses.|This is known as "Real-time Protection" that provides the first layer of protection against viruses.]

[If ever a virus is detected while the "Real-time protection" is active, it will be either deleted or cleansed depending on the type of virus.|When a virus is detected through the "Real-time protection" process, it will be removed or cleaned depending on virus types.|While the "Real-time protection" is activated and it detects a virus in the system, it will either clean or quarantine it depending on the detection type.] [Some virus scanners display a pop-up notification asking the user what action to take.

[Some scanners have different kinds of scanning options with the "Quick Scan" being the most common and frequently used by novice computer users because of the speed and convenience.|Virus scanners also provide different scanning options and "Quick Scan" is the one which is most commonly used because it is easy to use and understand.|The "Quick Scan" option on the virus scanner menu is frequently used by novice because of the speedy and convenient process.] [Although the way it works varies amongst virus scanners, most quick scans scan certain locations in the disk where common viruses are and automatically take the recommended action to deal with the virus to avoid user interaction.|Though different virus scanners work differently, quick scan feature just scans certain drives locations where common viruses can be found and they automatically take the necessary action.|Although quick scan works differently on many virus scanners, it still scans the commonly infected areas or computer drives to automatically carry out certain actions without user’s interaction.]

[Some viruses can be cleansed by the virus scanner while others are deleted and transferred to a special area called the "Quarantine".|Most viruses can be easily cleaned while the rest are deleted and moved to the “Quarantine” folder.|Virus scanners cleansed the viruses but there are times that they are just moved into another location specifically for “Quarantine” files.] [The quarantine serves as a storage center where infected files are placed and cannot be opened unless they are brought out of the quarantine.|The quarantine folder acts as the safety storage of infected files and these can’t be opened except by taking them out of the folder.|Infected files stay on the quarantine folder which is a safe place for viruses and they are inaccessible until you bring it out of this quarantined area.] [This allows you to bring clean files that were mistakenly flagged as viruses (also known as "False Positives"). |This enables you to take out the clean files that has been flagged as a virus even though it is not (called “"False Positives”).|Files that has been mistakenly flagged as viruses (referred as "False Positive
