It is highly likely that this error is a consequence of your antivirus software which has either:
- deleted the file
- moved the file to a quarantine folder, OR
- locked the file
We have seen this issue arise as a consequence of a false positive introduced in a recent update of virus definitions in several antivirus programs.
A false positive occurs when an antivirus program erroneously identifies a legitimate file or process as malware.
