.Dot files are Microsoft Word template documents, but cybercriminals are embedding Visual Basic for Applications (VBA) macro codes or viruses in them.
It is recommended that online users do not enable macros for files they receive from external or unknown parties. And, shoulid disable macros in Microsoft Office and do not allow them to run, even if prompted to do so.
The malicious .dot files only affect online users who have Microsoft Office installed. So, if you do not have Microsoft Office installed, the .dot file will be harmless to you.
If you have accidentally or unkowningly clicked on a malcious .dot file, scan your computer with the antivirus software installed on it. Do a full or complete scan.
