Worried my computer may have been hacked
About a month ago, I noticed some unusual behavior with my cursor - nothing being clicked on, but the cursor moving without my hand on the mouse. I thought this might be due to my not using a mouse pad and the mouse being on an uneven surface. I have Norton Internet Security. In addition, I downloaded AVG and scanned and found nothing.
I have a very long list of passwords saved on a MS word file. I access this file many times every day. Yesterday, I accessed the file at least once without a problem. Later, I tried to access the file under recent documents but when I clicked on it, it said that the file did not exist. I noticed a file name under recent documents which I'd never seen before ~WRL0088. I clicked on this file name and there were my passwords. I don't know how this happened. How did my passwords get saved under a different name?
I decided to run Spybot. The only thing Spybot found which looked suspicious was IronInstall.Toolbar.Amazon which I had Spybot remove. After this, I ran Malwarebytes and it found nothing.
Today, I found my recent documents had been wiped. I can't find my password file or the ~WRL0088 file anywhere on my computer. The recent documents might have been wiped when I ran Spybot and Malwarebytes. I thought that at least the ~WRL0088 file (where my passwords were located yesterday) would still be there, but it's not.
I checked my bank account and several credit cards and everything is as it should be. If someone has my passwords, they haven't done anything to these accounts.
So, do I have a serious problem or not? How did my passwords get saved under a different name and then get deleted? Could have hit some keys and caused this to happen unknowingly?
Thanks for any help!
