I'm new to the IT Security Stack Exchange! This is my question: I've Skype installed on my Windows 7 computer. In the last few months I've noticed my mouse cursor blinks (I mean it shows that cursor that appears when the computer is processing something) every time I type or click while Skype is the "focus" of my attention.
I think this could mean someone has installed a keylogger or some kind of malware on my PC. I think I could also just be paranoid about this. This happened some time after I gave out my Skype name online because somebody wanted to collaborate with me on a project.
I've ran multiple antivirus scans with Avast! free AV, scans with MalwareBytes Anti Malware, and even during Safe Mode on that computer. Not one scan has turned up any kind of malware threat detection!
Another important detail is I keep getting unsolicited contact requests on Skype as well. I don't know who they are so I decline and mark them as spam.
I wanted to ask this question here though I don't know if its much to go on. I don't know a whole lot about computer security.
