Pattern matching

Using a process called "pattern matching," PC-cillin draws upon an extensive database of virus patterns to identify known virus signatures, or telltale snippets of virus code. Key areas of each scanned file are compared against the list of thousands of virus signatures that Trend Micro has on record.

Whenever a match occurs, PC-cillin takes the action you have configured: Clean, Delete, Quarantine, Pass (Deny Access for Real-time Scan), or Rename.
