Jotti's Malware Scan review
A free web-based service for checking suspicious files with multiple antivirus programs.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Jotti's Malware Scan is a free, web-based service for people who want to check suspicious files with several antivirus programs. It focuses on file submissions rather than broader security functions, making it a fit for individuals and small organizations seeking an additional file check. The service cautions that no security solution offers complete protection, so it should not be treated as a substitute for a broader security approach.
For file checks, Jotti allows up to five files to be submitted at the same time and supports files up to 250 MB each. That capacity is useful when a suspicious file is too large for services with tighter limits or when several files need checking together. The service does not specify the number of antivirus programs used, so the value here is access to several engines, not a stated scanner count or a detailed analysis report.
A notable trade-off is how submissions are handled: Jotti says submitted files are shared with antivirus companies to help improve their detection accuracy. That may suit users prioritizing multi-engine checks, but is a poor fit for files that should not be shared with third parties. Choose Jotti for a free, straightforward check of suspicious files within its size and batch limits; look elsewhere if you need analysis beyond submitted-file scanning or cannot share the files with antivirus companies.
