4.1 Why Antivirus Might Flag It

Many lightweight system cleaners get flagged by antivirus for three reasons:

  1. Heuristic detections – The tool directly manipulates temp folders, browser data, and the registry. This behavior mimics malware.
  2. Lack of code signing – Most independent developers do not purchase EV certificates ($300+/year). Unsigned executables are treated suspiciously.
  3. Old packers – If the 832KB EXE is compressed with UPX or similar, some AVs see this as obfuscation.
