Which virus is identified by the family name Win32/Simile that targets Windows systems?

• A. Metamorphic viruses
• B. Win32/Simile
• C. Shell virus
• D. Time bombs

Answer: (B)

Win32/Simile is a Windows-targeted malware family. The “Win32” prefix indicates it runs on Windows and typically uses Windows API calls, while “Simile” names the specific family within that Windows-focused labeling. This makes it the best match for a virus identified by that family name, since the name itself denotes a Windows-oriented group of related samples.

Metamorphic viruses describe a technique where code mutates to avoid detection, not a Windows-targeted family name. A shell virus refers to viruses linked to shell environments and isn’t the Windows-specific family name in question. Time bombs describe payloads that trigger at a certain date or time, not a family identifier.
