How can you tell if someone has linked to your computer?

It seems that whenever I send an e-mail someone is able to read it. How can I tell if someone has linked in? Is it possible to fix this issue? My password hasn't been given out either!!!

How can you tell if someone has linked to your computer?
emails are not secure by default. when it leaves you computer it is on the clear, if you are using some sort of email client you can install PGP (Pretty Good Privacy) to secure your email.





if you are using a browser email like gmail, logto https://gmail.com instead of www.gmail.com, it uses some kind of encryption to hide you data from being clear to everyone.





I don't know if yahoo and msn support https, but I know gmail does.
Reply:First check the options of your email client to see if someone has hacked in and added a secondary and/or forwarding email to your account.





Second, change your password on your email account and on any other accounts that used that password. It would be wise to change all passwords.





If you suspect someone has breached your web based email then the only way to see if there are logs would be to contact the ISP / email providor and have them investigate the issue. If you know for a fact someone has done something criminal you can ask the District Attorney and police to get invlved and they have the power to subpoena the logs from the ISP/email provider.





You can look on your own computer for any third party remote access software such as check add/remove programs for things like pcanywhere, vnc, goto my pc.. and remove them





Right click on My Computer %26gt; programs %26gt; Remote tab %26gt;make sure both remote assistance and remote desktop are unchecked





Check services for anything they could be connecting to you through... such as disable messenger, fast user switching, telnet... don't disable if you arent sure what you're doing.





Make sure your have antivirus / firewall suite installed from a reliable vendor like mcafee...make sure its up to date, properly configured, automatically updating and scanning...





turn on your own logging on your system for events such as logins, etc...





Make sre your computer has a windows login password set, the screensaver is set to ask for password and to go into screensaver after 5 min of inactivity and put a BIOS password on the computer.





good luck.,
