Why we think so
0 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The file carries a valid ESET, spol. s r.o. signature and none of the 62 antivirus engines that checked it flagged it. In five sandbox runs it installed the ESET Online Scanner into the user profile and contacted only ESET and certificate-status servers. It has been submitted by over 2,300 sources since it was first seen on Jul 9, 2026.
The executable is signed with a verified certificate from ESET, a publisher on our trusted list. None of the 62 antivirus engines that checked it flagged it, including 14 major antivirus engines that returned clean results. Sandbox runs show it unpacking ESETOnlineScanner.exe and supporting libraries into the user's AppData folder and creating shortcuts, which matches the product it claims to be. Network contacts went to ESET download, banner and scanner hosts plus certificate status checks, and none of the 14 hosts we checked are known bad. The community YARA matches are generic anti-debug, certificate and compiler rules that ordinary software triggers.
What We Detected
None of the 62 antivirus engines that checked it flagged this file. It carries a valid code signature from ESET, spol. s r.o., and has been submitted by 2,384 distinct sources since it was first seen on Jul 9, 2026. Five community YARA rules matched, all generic checks for anti-debugging, certificates and compiler traits.
Threat Behavior
Across five sandbox runs the file launched esetonlinescanner.exe and its helper process, wrote the ESET Online Scanner program files and shortcuts, and contacted ESET servers and a certificate-status service. No injection into another process was recorded and no high-risk techniques were observed. An outside sandbox mentioned in a community comment gave a moderate malicious score, but its listed network activity was limited to ESET infrastructure.
What To Do Now
The file is consistent with the official ESET Online Scanner. Download it from ESET's own website when possible, keep your existing antivirus enabled, and confirm the ESET signature in the file properties before running it.
Where this verdict could be wrong1 caveat
- A community comment reports an outside sandbox scoring the file 42/100 as malicious, but that run listed only ESET-owned domains and none of our recorded sandbox verdicts were malicious.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
