I stupidly saved an .exe file that claimed to be an urgent Firefox patch (318K).
I haven't (and won't) run it, but how can I delete it so that it's gone, i.e. no risk to my Win7 laptop?
I thought of opening a large file (like a photo) and saving that as the malware file name, hoping to overwrite it... but after looking around here feel doubtful that that would work. Kaspersky AV didn't find any problem with it but I want it gone.
As it happened, I couldn't attend to this for the last few days, and in the interval Kaspersky learned to recognize it. I went looking for the file, and found it in quarantine--where I'll leave it.
Thank you everyone for your answers. I guess I had the idea that even if a malware file was deleted, it might somehow have the ability to self-activate, or accidentally be activated in some way. It's a relief to know they're not quite as magical as I imagined.
