Is fitgirl-bins.md5 safe?
This 836-byte checksum text file drew no detections from 76 engines, including 18 reporting tier-1 engines, and has no corroborating threat intelligence.
The file is a small MD5 checksum list rather than an executable, and 0 of 76 antivirus engines flagged it. Its hash has been observed for more than seven years, while MalwareBazaar and YARAify supplied no corroborating malware evidence; no runtime or complete network-reputation assessment was available.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The file is a small MD5 checksum list rather than an executable, and 0 of 76 antivirus engines flagged it. Its hash has been observed for more than seven years, while MalwareBazaar and YARAify supplied no corroborating malware evidence; no runtime or complete network-reputation assessment was available.
No antivirus engine flagged the sample: the result is 0 of 76, with 18 reporting tier-1 engines also finding no detection. The file is only 836 bytes and identified as text with an .md5 extension, which is consistent with a checksum manifest rather than executable content. Its hash has appeared across eight submissions over more than seven years without developing a malicious label. MalwareBazaar returned no hit, and YARAify matched no rules. Runtime behavior was not observed, and contacted-host reputation was not checked or saved, so those areas provide neither reassurance nor evidence of compromise.
What We Detected
The sample is an 836-byte text file named with an .md5 extension, a format commonly used to store checksum lists. None of 76 antivirus engines reported it as malicious or suspicious; 18 reporting tier-1 engines, including BitDefender, Kaspersky, Microsoft, ESET-NOD32, and Fortinet, also produced no detection.
Threat Behavior
No completed sandbox observation is available because behaviour is null, so no runtime claims can be made. The contacted-host cross-check was also not completed or saved. MalwareBazaar had no matching entry, and YARAify returned zero matching rules.
What To Do Now
The checksum file itself presents no supported malware indicators. If it accompanied downloaded software, assess and scan the actual archives or executables separately, because a benign checksum list does not establish that every referenced file is trustworthy.
Where this verdict could be wrong2 caveats
- behaviour=null, so the text content was not examined through completed runtime observation; this is neutral missing coverage rather than behavioral reassurance.
- contactedHosts=null, so no complete contacted-host reputation result is available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/76 antivirus engines reported a detection.
- 18 tier-1 engines reported no detection.
- The sample is a non-executable 836-byte text file.
- The hash has been observed for more than seven years.
- MalwareBazaar returned no hit and YARAify matched zero rules.
- No completed runtime observation is available.
- No complete contacted-host reputation result is available.
- The accompanying files referenced by the checksum list were not part of this assessment.
No action is needed for this checksum text file itself. Keep endpoint protection enabled and scan any referenced archives or executables separately before opening them.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Open it only when its sender or download source is one you independently trust.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
