Yes, I am absolutely sure.
It is possible by accessing the Internet without a firewall, without a properly set antivirus program and if you have any less then all four programs I listed. Even then it is still possible, but I have over 5 years of experience with home computer security for friends, family, ex-girlfriends and acquaintences behind me so I know what I'm talking about.
There's no easy way out of what happened to you unless you had accidentally pressed the F11 key without noticing, but it doesn't sound like you did that.
