Avast is antivirus software that is freely available to download for personal users. Avast HTML document is a file type that the antivirus software converts other documents into, like words docs and PDFs. Users are reported to have issues with their documents since they have installed Avast security software or have scanned their file system using it. Their Word documents or PDFs get converted into a different file type, namely, Avast HTML Document. Due to this, users become unable to use, modify, or edit their files as they intend to, which leads to a decrease in the users’ ease of use and productivity.

Text Documents in Avast HTML Document format
PDF, short for Portable Document File, is a standardized file format introduced by Adobe. It was designed explicitly with text documents in mind. Today, the PDF file format has become a standard for rich documents in almost every field. The most widely used software used to view or edit PDF files is Adobe Acrobat. The same is with word documents, a file format designed by Microsoft. These are also rich text files that can contain graphical elements in them. Both formats are different, but one can be converted into another and vice versa.
HTML stands for HyperText Markup Language, is an entirely different file format, That was designed to transfer Web pages across the Internet. All these file formats are different, with other byte-level arrangements and encodings. Hence, when Antivirus converts these files into Avast HTML document format, they become utterly unusable. As we will see later in this article, there are ways to change the default application for a specific file format to work around this issue.

This is not that big of an issue, as the problem can be resolved by changing the default application for videos files. The files do not get corrupted or infected with viruses, as most users assume. It is just that they do not get opened in the intended media player software.
