Numerous user reports indicate that this specific filename (or variants) is flagged as malware by security software.
Since many of these files originate in temp folders, use the Windows tool or manually delete the contents of %TEMP% to ensure no backup copies remain. Final Verdict

Beyond these generic warnings, there are more specific reasons an antivirus program might identify a threat. During analysis, some security vendors identify the presence of PE32 executables packed with protection tools like Themida. These tools are often used legitimately to protect software from being cracked, but they are also employed by malware authors to obfuscate their code from detection engines. This practice of "packing" can lead to , where the antivirus software cannot definitively determine the file's intent and errs on the side of caution. A thread on the Huorong Security forum notes that a file with a similar pattern was diagnosed as an "infection-type virus rather than a Trojan," implying a legitimate file that had been externally infected.

: A far more reliable method than a filename is to use the file's unique cryptographic hash (SHA-256) . You can calculate this using built-in Windows tools like certutil . Once you have the hash, you can search for it on malware databases like VirusTotal or Triage to see if it has been previously cataloged as a specific threat.
