Computers are all around us. They aid us in our play and work, keep track of patients in hospitals, and manage crucial manufacturing processes. This ease of use has a drawback since more computers are targets for malicious coders.
Antivirus protection scans files and programs to identify potential threats. It acts as a real-time shield against cyber attacks. It can identify infected files or programs based on their signature – a few lines of assembly code that overwrite the stack pointer, as an example – and avast unprotected then compares them with a database of known malware. If the program is found to match the antivirus software, it blocks it from running or shifts it to quarantine, so it can be thoroughly analyzed and scanned.
Unfortunately, the creators of malicious software continually create new programs that have distinctive and subtle signatures. Antivirus programs need to update their databases. Once a virus is identified and added to the detection database, hackers will be unable to use the same signature on other computers.
This is why the majority of trusted antivirus programs include several additional features to help guard against a wider array of malware threats. These include:
