So we have few listed here which are – virus, worms, Trojan virus, and spyware which various form of malware. Viruses, for example, then to cause disorder on a computer’s hard drive by deleting files or directory information.

How does anti-malware software do its job?
Many programs scan for malware using a databank of known malware definitions (also called signatures). These definitions helps to figure out how the malware works and how to recognize it.
If the anti-malware program discovers a file that matches the definition, it’ll flag it as potential malware. This is the best way known to get rid of any known threats, but one things it needs is regular updates to make sure the program doesn’t miss out on newly developed malware.
Another method to detect anti-malware or bad software is a procedure of analysis called heuristics. An unconventional database scans, then heuristic analysis allows anti-malware programs to detect threats that were not formerly discovered. Heuristics adopts the method of identifying the malware by behaviors and characteristics, instead of comparing against a list of known malware.
A good example of this analysis is that if an application is designed to remove important system files, the anti-malware software may flag it as malware (since applications should not be doing that). Sometime heuristic analysis can come out as “false positives,” or programs flagged as malware that are actually legitimate.
A third method to remove malware is by running a program it suspects to be malevolent is in a sandbox, which is a protected space on the computer. The program is made to work in its full capacity, where it has complete access to the computer when, in fact, it is running in an enclosed space while the anti-malware monitors its behavior.
If it reveals malicious behavior, the anti-malware will terminate it. Otherwise, the program is allowed to execute outside the sandbox. Though, some forms of malware are clever enough to know when they’re running in a sandbox and will stay on their best behavior…until they’re allowed free access to the computer.
