What Is an Online Virus Scanner?

An online virus scanner operates by searching for the signatures of known viruses. Essentially, a virus’s signature is its fingerprint. A virus signature is a string of characters or binary computer code. Viruses may share the same signature, making virus detection easier for antivirus programs. Many experts state that online virus scanners go hand-in-hand with other offline, desktop-based anti-virus programs for the best protection.
