..it could be the recent log file which was created during the Windows Update installation of MSXML 4.0 or 6.0. They were optional updates that came with .NET Framework 2.0 and 3.0.
During the update, there was a folder created on the C drive which also contained a text file which had "MSXML", or something similar, in it's file name.
Unfortunately, you've not told us anything about your computer (EXACT name of the folder and file, operating system, etc.) so it's hard to make any other educated guess.
And if you think it's "malicious", have you tried scanning the machine with multiple malware scanners? If so, which ones?
Hope this helps.
I see a folder on my C drive with a name that is composed of a whole bunch of gibberish letters and numbers. The folder conbtains a text file with a name that composes of equally gibberish letters and numbers. Can someone please tell me what's the purpose of its existence? I'm starting to suspect it's malcious.
