Sivis is a file-infecting virus family that overwrites legitimate executable files with malicious code, often causing system instability and data loss. Unlike modern stealth malware, Sivis is destructive and noisy, frequently corrupting files beyond recovery. It typically spreads through infected removable drives and network shares. Sivis infections often require restoring files from clean backups because in-place removal cannot recover overwritten code.

Sivis is a file-infecting virus that prepends or appends its code to executable files, spreading when those infected executables run.
Modified file sizes and timestamps across executables, unexpected slow startup of common programs, and AV detections for Sivis are diagnostic.
