top pageYou can upload files to suddenly and you can scan up to 64 MB files. Click "Select file" ...


Select the file you want to check if it is a virus and click "Open". However, files uploaded for virus checking are released to security vendors and so can not be used for files containing confidential information.


Click "Scan" at the bottom of the page.


Then I got a message saying "It is an analyzed file". It seems that someone else has already checked the same file. To see the results of the previous check, click "Last analysis result" OK. If you want to check it again, click "Reanalyze".


"I registered a file in the queue, please wait until the analysis starts".


Within 1 minute the analysis was completed and the analysis result was displayed automatically.


The detection rate is "2/67", which means "I checked with 67 antivirus software, but it was judged as virus by two software". In addition, details of the analysis result are displayed at the bottom of the page, and you can check "what kind of antivirus software caught you" or "what level of engagement is you". This time we used "TrustViewer"Is a tool that remotely manipulates a PC, so it is considered highly probable that a false detection is made out by two software.


また、ファイルだけでなくウェブページの安全性もチェックすることができます。ファイルの隣にあるURLをクリックし、調べたいウェブページのURLを入力して「スキャンする」をクリックします。今回はGIGAZINEのページをチェックしてみるので「https://gigazine.net/」と入力しました。


It seems that someone else has already checked it. To confirm previous analysis, click "Last analysis result" OK. This time we will re-analyze.
