How does an antivirus detect a virus?
I know there are a lot of techs here on HB. I just wanna find out how an antivirus can detect a virus.
One way is by finding a unique piece of code within the virus and comparing it.
Much like a real-life doctor, at the time of designing, antivirus are "taught" how most "viruses" are coded, and how they work. Sorta like a doctor knows how certain symptoms equate to certain illnesses. Antiviruses have a database of "viruses" which they compare suspicious software with and offer their results/diagnosis. Every now and then, antivirus update themselves so they can be able to detect new "viruses".
