Jotti online file scanning
Jotti's malware scan is a free service that lets you scan suspicious files with several anti-virus programs. You can submit up to 5 files at the same time. There is a 250MB limit per file. Please be aware that no security solution offers 100% protection, not even when it uses several anti-virus engines. All files are shared with anti-virus companies so detection accuracy of their anti-virus products can be improved.
