ESET Online Scanner is a free, one-time malware scanner for Windows PCs from ESET. It finds and removes threats on demand and offers 64-bit and 32-bit downloads, but provides no ongoing real-time protection.
ESET is best known for its paid security suites, but its Online Scanner is a free tool for a single job: checking a Windows PC once and cleaning up what it finds. It is handy when your regular antivirus has missed something or when a computer starts behaving oddly.
What a scan gives you
- Full system check: ESET’s detection engine looks through the PC for malware.
- Removal and quarantine: Detected items can be removed. Anything taken out goes to quarantine, where you can review and restore it if needed.
- A report: After the scan, you see a summary of what was found.
Steps
- The Download button opens ESET’s official Online Scanner page. A 64-bit version is offered, with a 32-bit build for older PCs.
- Launch the downloaded file.
- Start a full system scan and wait; a complete scan can take a while on a large drive.
- Read the report and decide what to remove.
Know what it is not
ESET describes the tool as a one-time scan that does not provide ongoing, real-time protection. It will not watch downloads or websites after the scan ends. For continuous protection, keep the antivirus built into Windows or another real-time product running; ESET offers a trial of its full protection for that purpose.
The Online Scanner is for Windows only. ESET’s page does not list specific Windows versions or hardware requirements.
Pros
- Free second-opinion scan
- Quarantine lets you restore false positives
- Works next to your current antivirus
Cons
- No real-time protection
- Windows only
Frequently Asked Questions
Can I run ESET Online Scanner with another antivirus installed?
It is designed as an on-demand, one-time scan rather than a resident antivirus, which makes it suitable as a second opinion next to your existing protection.
Can I get back a file that ESET removed by mistake?
Yes. Removed items are moved to quarantine, where you can review them and restore them if necessary.
