If someone physically installed a keylogger device on my computer, is there a physical record of its presence? Would it be listed as hardware or perhaps a service, and if so, what sort of names would I be looking for?
I had my computer repaired by a guy who is working in the computer field. I think his day job is programming. Anyway, I had a bad hinge on my laptop and he was recommended to me.
I've been experiencing strange behavior on my computer. He repaired it more than six months ago, but when I started feeling uncomfortable and suspected he might have messed with my computer I reinstalled Windows (7) and I'm still having issues. I've scanned with AVG and Malwarebytes and the report comes back clean.
First off he didn't charge me, which I found very odd. He just wanted me to submit a review on some professional website. I found that very odd that he didn't charge me.
After the repair, I learned that he rifles through customer's computers and has in the past found kiddie porn on some guy's computer and he reported him to the police. I don't have kiddie (or any) porn on my computer but I'm thinking he might not be the most scrupulous person to be doing business with. On top of that, I get a very unsettled feeling about him in general after talking to him for a while.
Some of the odd behavior includes:
1. When I sign into my email account, the computer screen switches to my normal desktop view and then reapirs.
2. I have had to change my password three times in the past six weeks on one forum I visit, a photography site.
3. Today I tried logging into my main email account and when I hit the fourth character, I was kicked out of the entry box. I was able to get in by typing the password in Notepad and enter it by copy/paste (and then changed my password immediately.)
4. I taped cardboard over the laptop camera lens. He moved that tape and exposed the lens.
I need to know if I can detect a keylogger from the computer or do I have to take it in and have it physically examined? And if there s a keylogger attached, can I take any legal actions against this individual? IF he did install something, I would leave it there untouched for fingerprints.
