Jotti is a free online virus scanning service that scans your files for virus. You can upload the file that you want to scan for virus, and Jotti will scan that file with multiple antivirus software. Then it reports you scanning results from all those antivirus software.
There is a similar popular service called VirusTotal that does similar service, and there really isn’t any advantage that Jotti offers over VirusTotal. However, if you are not able to use VirusTotal for some reason, or want a second opinion, Jotti is a good alternative for VirusTotal.
Services like Jotti and VirusTotal come handy if you have a file that looks suspicious to you, but your antivirus software does not shows any virus in that. In that case, you can just upload that file to Jotti, and Jotti will scan that file for free using multiple antivirus, and will let you know if any of them report a virus in the file.
Here are some of the antivirus software that Jotti uses:
.. and many more.
Jotti is extremely simple to use. You do not need to download anything, or register with Jotti. Just upload the file, and Jotti will report you the results of virus scanning. Jotti has a limitation of 20MB file size (VirusTotal has same limitation).
To test this service, I uploaded a file of 20MB, and within a few minutes Jotti finished scanning it with all the virus scanners, and showed me the result (see screenshot above for results of scanning). I do not have a virus infected file (that I am aware of;) ) so, I am not able to test its efficiency in finding viruses. However, because the virus scanning is actually done by the popular antivirus software listed above, I would assume a pretty good level of detection.
However, one thing I miss in Jotti is some of the popular antivirus software, like, McAfee, Norton, and Trend Micro. VirusTotal does uses these as well.
Nevertheless, as I mentioned earlier, Jotti is still pretty good as it uses many antivirus software.
Note: Jotti is not a replacement for your antivirus software, as it can be used for only selectively scanning for files. I highly recommend that you have a good free antivirus software installed on your system.
