Nothing Has Improved…the same email continues to arrive every day and is detected by Avast and deleted by me.

I went to your page about these worms, but really do not understand if this Ganda B could have infected my PC or is it just the nuisance Emails (never opened) that are just a nuisance, but doing no more harm. I did a search for the "scandisk.exe file…but the screen told me it was not a valid file name…

Please advise what else I should do…is this little ******* residing in my PC, or does he just arrive with emails and is therefore deletable with no harm done?

You can see I am a really simple person…no technical knowledge at all…so please tell me in simple terms if there is anything else to do.
