Dr.Web Online Scanner review
A free web scanner for submitted files and links, not a full-computer virus check.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Dr.Web Online Scanner is a free web service from Doctor Web for people who want to check a suspicious file or URL without installing a scanner. It scans submitted files with the latest version of Dr.Web Anti-virus and a current addition to its virus database, then displays a report. It is designed for individual items, not for diagnosing whether a computer’s full disk or memory is infected, so it suits quick web checks rather than comprehensive device assessment.
For file checks, the service accepts files up to 10 MB. Multiple files can be submitted together in supported archive formats, with a report for each contained file. URL checking is available separately through Dr.Web’s online link-checking service. Website owners can also embed free forms for file and URL scanning, making the service relevant beyond one-off personal checks. These focused options are useful when the task is to inspect a particular download, archive contents, or link; they do not amount to a full computer scan.
The scanner is free and web-based, with no paid tier described for these checks. Its main boundary is also important to the buying decision: Dr.Web says the online file scanner does not determine whether a PC is infected. Users who need that broader assessment should consider Doctor Web’s separate CureIt! utility instead. Choose Dr.Web Online Scanner for occasional submitted-file and suspicious-URL checks, or for an embedded website form; do not choose it as a replacement for full-disk or memory scanning.
