Signature-based Detection

Yeh sabse pahle tarika hai. Jiska use karke koi bhi Antivirus kisi malware ko detect karta hai . Kisi bhi computer mai sabhi tarah ki .exe file ko yeh scan karta hai kyoki jadatar virus inhi files mai milte hai .

Yeh sabhi .exe file ko scan karta hai or apne database mai virus definition ya signatures se match karta hai. Tab us file ko delete kar diya jata hai.

Aap Internet se jitni bhi files ko download karte hai. Veh sabhi files sabse pahle scan ki jati hai. Agar unme kisi tarah ki virus definition milti hai. Aise mai Antivirus us file ko detect kar leta hai or delete kar deta hai.

Heuristic-based Detection

Isme detection or signature based detection dono ka ik sath use hota hai . Ise aaj ke time mai sabhi Antivirus bnane vali companies use karti hai. Kyoki yeh signature based detection to karta hi hai sath hi un malware ko bhi detect kar pata hai.

Yeh lagbhag Behavioral-based Detection ki tarah hi kaam karta hai . Sandbox ek tarah ki computer security hoti hai. Jis par apke computers ke softwares kaam karte hai.

Isme kisi tarah ke program ko ek virtual environment par run kiya jata hai. Agar usme kisi tarah ka malicious code detect hota hai. Aise mai uske behave ki help se use detect kar liya jata hai or use delete kar diya jata hai.
