I am using an android smartphone, but I downloaded a very small txt file from a certain post and opened it.
At that moment, the processing speed of the mobile phone became very slow, and when I ran the file using htmlviewer, only a few lines of the encoded characters were listed.
After downloading it back to the computer and examining it with the kaspersky program, it turned out to be no problem.
I ran a vaccine program for smartphones, but it turned out that there was nothing wrong. The file's extension was also definitely .txt.
I would like to hear your opinion as an expert.
