One of my computer has been having this problem for sometimes now and I can't find what the problem is. Some removable disk (Flash Drive) when I insert it into the computer all the document, file change into weird things (see screenshot) and when I try to open the file (double click or open) a message come out saying that syntax is incorrect (see screenshot). But it does not happen to every single removable disk that I stick into the computer. However there's no connection with the brand of flash drive I use because I try two flash drive with the same brand (transcence), one has problem the other no problem. I scan it with hijackthis but the log is here: https://www.techspot.com/vb/topic116343.html (Computer 3) I'm at a lost as to what to do now. I've tried scanning virus (Kaspersky), spyware (MBAM, CCleaner) but it still doesn't work. Help please!
