What it is
Parite is a family of Windows file-infecting viruses. Security products may use names such as W32/Parite, Win32.Parite, or Packed.Parite for related samples or infected files. It modifies executable files and some dynamic-link libraries so the viral code runs when a contaminated program starts.
How it works
After execution, Parite becomes active in memory and searches local and accessible storage for files it can infect. Copying or running those files on another system can continue the spread. Because legitimate applications are altered, repeated detections may represent infected host files rather than dozens of separately downloaded threats.
Key points
Deleting every detected executable can make Windows or installed applications unusable.
An active in-memory component can reinfect files restored before the infection is fully stopped.
Shared folders, removable drives, and backups containing executables must be included in the investigation.
What to do
Disconnect writable shares and use an offline or trusted boot scan when possible.
Replace system and application binaries from clean installation media instead of unknown copies.
Scan backups before restoration and monitor for renewed file modification.
Reinstall the operating system if reliable disinfection and file integrity cannot be established.
