I have a HP laptop someone
cleaned out" and gave to me when my own crashed. I thought i was the only user and have given no one my password. But I noticed on my GMAIL account under "Recent Activity," a user had logged in from NY although all my log-ins previously had been from my town in Maryland. I sent the IP address to a friend at Trustwave who said it was something like an internet cafe in Brooklyn. Since then I have noticed there is always another user on my GMail account. It has a local address, as if it a user on my network. I do not know how to get rid of this. I sign them off, then change the password, and they are back immediately. Nothing gets rid of them. I have tried to disable all Remote access and they undo the disable keys. They have locked me out of files and even when i go to regedit and try to delete keys like HomeGroup or REmote Desktop or Remote Assistance as possible vulnerable points, they have somehow made them not delet-able.
I even forfeited all my files and did a complete System Restore on the computer, but still it persists. Can you help?
Software/Hardware used: used malwarebytes but it failed as my os is windows 7.
