OK, long story, best I start at the beginning. I work on Outlook Express and the other day I was looking for a specific e-mail I had sent to a specific person. I found this group of e-mails in the list all sent on one specific day from my e-mail address (I did not send these e-mails). On further investigation when opening the e-mails (clever hey?!) I found that these specific e-mails sent dates and times change as my computer date and time changes. A couple of days later this happened again. Then suddenly one of my profiles was blocked because my password had been "stolen". I changed all passwords on all my profiles. Then the above happened again. I ran malware bytes and found something called Koobface.trace. I have reason to believe (due to some circumstances) that someone is trying to get into my files. What is happening and how do I stop this from happening, AND MOST IMPORTANT OF ALL - HOW DO I CATCH THEM????
