AV

How it works

• It compares files to a database of known malware fingerprints, updated several times a day.
• Newer versions add checks for suspicious behaviour.
• Windows ships with Microsoft Defender Antivirus, a solid baseline.
• The gap is anything brand new, anything that runs only in memory, and legitimate tools used for harm.

What can go wrong (example scenario)

A three-person engineering firm ran a laptop with antivirus switched off because it “slowed down CAD”. A cracked plugin from a forum installed a keylogger. Their bank login was captured within a week.

How WILDCARD handles it

Workstation Defender goes after what standard antivirus misses: ransomware, fileless malware and zero-days. It is next-generation EDR built for business, so it watches behaviour as well as known signatures.

• A dental office's front desk computer needs baseline scanning plus something that watches for ransomware behaviour.
• A contractor's laptop that visits job sites and public Wi-Fi gets exposed to more than a signature list can cover.
• A non-profit running donated older PCs assumes the free antivirus is enough.

Example scenario: A small law office relied on the free antivirus that came with their PCs. A clerk opened a resume attachment with a macro. The antivirus saw nothing because the macro downloaded its payload later, in memory. The firm's files were encrypted by morning.

A question owners ask

Windows has Defender built in. Isn't that enough?

It is a good baseline and we keep it on. A business computer also needs detection and response that watches behaviour, because the attacks that hurt small businesses are the ones no list has seen yet.
