Verdict Suspicious
Is Classic Paint- 1. 1- setup. exe safe? Treat it as suspicious.
One less reliable engine flagged the sample while 17 major antivirus engines reported clean.
Why Suspicious? One antivirus engine (APEX) flags it; nothing else confirms it.
Limited evidence · One sign points to a problem; nothing else confirms it.
Treat as suspicious; avoid execution until additional verification or a signed version is obtained.
What to do now4 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't install it unless you're sure where it came from.
Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.
If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.
If you already installed it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Why we think so
3 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Sandbox behaviour includes multiple offensive MITRE techniques and direct-IP contact to 20 addresses with no domains. Prevalence is widely seen and long established for an unsigned installer, producing mixed signals.
The engine profile is a textbook less reliable-only false-positive pattern, yet the sandbox captured genuine offensive techniques and direct-IP a control server that are rarely seen in legitimate commodity software. Files built with the same import table have received both safe and suspicious verdicts, and the file remains unsigned with no trusted publisher history. The combination of high-severity rules and behavioural red flags outweighs the clean major majority, placing the sample in the suspicious band.
What We Detected
69 engines scanned the file; only APEX (less reliable) returned a malicious label. Seventeen major antivirus engines reported clean. The sample is an unsigned Inno Setup installer (ClassicPaint-1.1-setup.exe) that has been submitted by over 2,200 sources since 2022.
Threat Behavior
Sandbox execution revealed 12 offensive MITRE techniques including process injection (T1055), credential dumping (T1003), data destruction (T1485) and service creation (T1543.003). The sample contacted 20 external IP addresses directly with zero DNS lookups and wrote multiple dropped files under Program Files\Classic Paint.
What To Do Now
Do not execute the installer. If the file was downloaded from an official Winaero source, obtain a fresh copy and verify its digital signature. Submit the sample to additional sandboxes for deeper behavioural analysis before any further use.
Where this verdict could be wrong1 caveat
- Unsigned installer with high-entropy sections and direct-IP a control server raises suspicion even at widely seen and long established prevalence; the single less reliable detection alone would be ignored but the sandbox behaviour tips the balance.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

- Common_old prevalence (2210 submitters)
- No malicious files it created

What the test run showed
What the file did on a test computer
Confirmed in the test run
Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).
Moderate concern: Ran commands or a script on the test computer.
Moderate concern: Used an unusual way to talk to a server.
Moderate concern: Unpacked hidden content while it ran.
Moderate concern: Checked whether it was running on a test computer.
Note: Read the user name of the test computer.
Note: Listed the programs running on the test computer.
Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as password-store access, but nothing touched the Windows password store.
Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.
Not confirmed: A sandbox rule tagged this run as creating a service; no new service was recorded.
Not confirmed: A sandbox rule tagged this run as setting up auto-start; no auto-start entry was recorded.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.
