My boyfriend let his friend who is an experienced self-professed hacker to help "fix" issues he was having with his computer. My boyfriend's computer is running on Windows XP and my understanding is that he used the Windows FTP (and accessed his computer using his IP Address) to gain access.
My concern is that he was able to gain valuable info from his computer for the 5+ hours he was supposedly "troubleshooting" My boyfriend is not from the technology industry and only uses his computer for emails and basic web browsing, so he was relatively unfamiliar with the threat that this might cause him and did not see this access as a potential threat.
This individual is supposed to be his friend, but I am concerned in the time he had access he could have a.) installed spyware, keystroke loggers, b.) uploaded info/files to his computer, or c.) changed settings or done something so that he could access the computer at any time at will (whether my boyfriend gives him FTP access or not.
My question is this: (I was not sure if I should post this on the boards so if it's better-suited to a specific category or topic heading, please advise).
How can we tell - ie. are their log files, or access files we can find out what programs were accessed or what documents accessed or what files uploaded during that time that he was on (2 nights ago) that would tell us if the security was breached or if he downloaded any stealth software or reset any settings on his computer? If not, what can we do to protect his machine (other than purchasing a new computer)?
Obviously, I am VERY upset about this because there is a ton of personal and financial info on that machine that does not need to be known by this individual...or anyone for that matter.
Please, can you help me? You can email me via this site please? Thanks so much in advance for your help!
