The Curious Case of the Disappearing Files: A Dive into Digital Forensics


Could you assess the legitimacy of an HTML file named ‘license.chromium.html’ that appeared after an inadvertent click during a school assignment submission? I noticed multiple files related to Microsoft Edge were created on February 7th, a date when I don’t recall using my laptop. Despite an extensive search, I’m unable to locate these files on my system. Considering my primary use of the computer is for academic purposes, and barring the unlikely event of an ad from Reddit being the cause, I’m puzzled about the origin of this potential virus. Additionally, I’m curious if a virus from my old Android device could have been transmitted to my laptop via my home router.


When unexpected files appear on your computer, it’s natural to be concerned about their legitimacy and potential harm. The file in question, ‘license.chromium.html’, could be a benign component of the Chromium project, which is the open-source foundation for many web browsers, including Microsoft Edge. However, without seeing the file’s contents or behavior, it’s impossible to definitively assess its legitimacy.

The creation of multiple files related to Microsoft Edge on a day you don’t recall using your laptop is unusual. It’s possible that an automatic update or sync process occurred, but it’s also wise to consider other explanations, including unauthorized access or malware.

The inability to locate these files is concerning. They might be hidden, which is a common tactic used by malicious software to avoid detection. It’s recommended to use advanced system tools or enlist the help of a cybersecurity expert to examine your system more thoroughly.

Regarding the use of your computer for school work, it’s unlikely but not impossible for a virus to infect your system through an ad from a website like Reddit. Malvertising, the use of online advertising to spread malware, can sometimes bypass typical security measures.

As for the potential virus transmission from your old Android device to your laptop via your router, it’s a low-probability event but not outside the realm of possibility. Viruses typically exploit vulnerabilities within the same ecosystem, but cross-platform infections can occur, especially if devices share the same network and have security weaknesses.

In conclusion, while the ‘license.chromium.html’ file might be harmless, the circumstances you’ve described warrant a cautious approach. It’s advisable to conduct a thorough security scan, update all software to the latest versions, and consider changing passwords. If the issue persists or you find evidence of a virus, contact a professional for assistance. Remember, better safe than sorry when it comes to cybersecurity.
