Verdict Safe
Is VCRedist_ AIO_ x86_ x64. exe safe? Yes, no threats found.
A widely shared all-in-one Visual C++ runtime repack; only 2 of the 70 antivirus engines that checked it flag it, no major antivirus engines does, and sandbox runs showed…
Read the whole reasonShow less
Strong evidence · Widely seen for a long time, and nothing harmful found.
This runtime pack appears to be a common false-positive case; if you prefer certainty, install the official Visual C++ redistributables directly from Microsoft instead.
Good practice2 tips
We found nothing harmful in this file.
Run it only if it came from the developer's own website or an official app store.
Keep your antivirus and Windows updates switched on.
No scanner can promise a file is 100% safe.

Why we think so
2 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Only ClamAV and VirIT flag this file, with labels for an installer bundle and a generic backdoor, while all 18 major antivirus engines report nothing. Sandbox runs extracted and installed Visual C++ and Visual Basic runtime packages, and thousands of users have submitted it over almost a year.
Two of the 70 antivirus engines that checked it flagged the file, neither of them a major antivirus engine, and their labels disagree with each other. The file has been submitted by 3,692 distinct sources over 329 days, which is typical of a popular unofficial runtime pack. The combined sandbox verdict was clean, recorded no high-risk techniques, and showed a 7-Zip self-extractor writing Microsoft runtime installer packages. No observed network contact was the sample's own, and the four checked hosts carry no malicious reputation. The file is unsigned and listed without a family in a public sample database, so it is a third-party repack rather than an official Microsoft download.
What We Detected
2 of the 70 antivirus engines that checked it flagged the file: ClamAV with an adware installer-bundle label and VirIT with a generic backdoor label. None of the 18 major antivirus engines detected anything. The file is unsigned and appears in a public sample-sharing database with no malware family named.
Threat Behavior
Across five sandbox runs the file unpacked a 7-Zip self-extracting archive and ran an installer script that wrote Visual C++ 2005-2010 and Visual Basic runtime installer packages. No injection target, persistence, or network activity of its own was recorded, and the sandbox verdict was clean.
What To Do Now
The evidence points to a common unofficial runtime bundle. Where possible, prefer the official Visual C++ redistributables from Microsoft, and keep your antivirus enabled during installation.
Where this verdict could be wrong2 caveats
- The file is an unsigned third-party repack of Microsoft runtimes, so its contents cannot be tied to Microsoft by a signature, and ClamAV labels it as an adware-style installer bundle.
- The hash appears in a public malware-sample sharing database, although that listing names no family.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No major antivirus engines detects the file.
- Submitted by thousands of distinct sources over nearly a year.
- Sandbox runs returned clean and showed only runtime package installation.
- No high-risk techniques or injected processes were recorded.
- The installer is unsigned and is a third-party repack, not an official Microsoft package.
- ClamAV labels it as an adware-style installer bundle.

VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
These identify the compiler, runtime or installer used to build the file. They are not packing and are not a risk signal on their own.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
