Do you have to open .exe file to get virus?

I'm sorry for asking such basic question, but it's been years since I've gotten a serious virus.

Long story short, I saved this file called 'dante.exe' to my 'downloads' folder from Mozilla Firefox Browser. Upon download completion, AVG Free Anitivirus window popped up telling me that dante.exe is a threat (trojan spy).

I immediately go to my download folder and delete the file, then click on 'removed threat' on AVG window, which was successful.

Then I proceed to scan my HDD with 5-6 different anti-spyware/anti-virus programs. All of them say my HDD is clean.

However, I'm still seriously considering reformatting my hard drive. (or is it already too late?) :(

So what I want to know is that is it possible for the virus/spyware to infect your computer by simply saving it in a folder and not open it?

My main concern is password stealing and keylogging capability of this trojan spy.

Thanks.

I doubt that it did any damage if you didn't run the .exe. Reboot the PC, don't open any windows other than a command prompt & run netstat -an

Look for any unwanted connections in the foreign address column. Post the output here if you don't understand it.

Thanks for the fast reply,

Here's the log:

192.168.1.6 is my desktop (where I downloaded the trojan exe)
192.168.1.4 is my laptop (connected wirelessly)

Let me know if you need me to turn off my laptop and run netstat again.

I don't see any unwanted connections in the desktop. The entire output doesn't show on the laptop but I don't think you need to do anything else.
