Scan your Windows computer for malware for free with the ESET Online Scanner! Free online virus scanner checks for any type of virus and helps you remove it. Remove any virus without installing antivirus software! One-time scan to remove malware and threats from your computer for FREE!

Full protection with ESET Internet Security!
  • Real-time, 24/7 continuous protection
  • Detects and removes threats in background
  • No commitment – try 30 days for free
ESET Online Scanner offers a one-time free scanning tool that allows you to detect any potential issues on your system. While future scans or problem fixes may require payment, the software does provide a free trial for thirty days after the initial scan. It can be used alongside existing antivirus programs and is capable of deeply scrutinizing your system for viruses and quickly removing hazardous files.

However, it does not provide continuous protection against harmful components, so regular one-time scans are recommended. The software is easy to deploy as it is web-based and does not require installation.

Users can customize the scan by selecting the components to include and have the option to enable or disable the detection of potentially unwanted applications. Advanced options can be accessed to uncover unsafe apps, scan archives, enable Anti-Stealth technology, and clean threats automatically.

Although not as powerful as paid antivirus software like ESET NOD32 AV, ESET Online Scanner offers more frequent updates to its virus and malware library compared to many free online checkers, making it a sufficient option.

This software performs scans and effectively detects cookies present on your system. It is compatible with all popular browsers, allowing for widespread usage. Additionally, it is capable of identifying and removing malware from your system.


One drawback is that it sometimes provides false positives, which may be used as a tactic to encourage you to make a purchase. Another limitation is the presence of paywall-restricted features, potentially limiting the full functionality of the software unless a payment is made.

Note: One-time scan and remove.
