Teamviewer is one of the fastest and most secure way to allow remote access to your computer. All you have to do is download the file by clicking the logo above and Run the install. After the install is done it will provide you with an ID and a password. Similar to whats shown below. Once you have this ID and password, you would then contact me by email, facebook, myspace, AIM, MSN, Yahoo messengers.
LogMeIn is a bit more complex to setup in the beginning but would be used possibly for long term support.
