So many of the scammers these days are attaching malicious PDF files in their email messages. They also send text messages to your mobile number and in these messages, there is usually a link leading to download of harmful PDF files. If you have downloaded such a PDF file and you open it on your computer or mobile phone, it might cause serious damage to your device which includes infection with a bigger and badder malware.
So if you have already downloaded a PDF file but are suspicious that it could be laced with malware code inside, you can scan it quickly online using Maldoc Scanner. It is a Quicksand Framework based documents and PDF files analyzer hosted by security researchers Tylabs.
Here is how you can quickly scan any suspicious PDF file:
- Visit https://scan.tylabs.com/ in your web browser.
- Click on the Choose File button and select the PDF file that you want to scan from your computer.
- Click on the Scan Document or PDF button to start the scan.
- After the selected file is uploaded to the Tylabs server, it will be scanned. In a few seconds of time, the analysis results will be shown on your screen. There is a risk meter that displays whether the PDF file is risky along with the risk score. It also shows the details of suspicious/malicious objects found inside the PDF file.
Basically if the risk meter needle is showing green with a score of 0, then you can use the PDF file without problem. But if the file is displayed with the needle in yellow, orange or red zone, then you should stay away from this PDF file.
It is a good idea to keep a good antivirus software installed on your computer that can scan for malicious PDF files before they can cause any harm to your file system. There are many free antivirus products such as Avast.
