Weird right-click problem

[Thomas42]

Yesterday evening I started having a weird bug with my mouse. Whenever I right-click on an icon, explorer.exe shuts down. That means I can't rename, or copy-paste stuff (Ctrl-C/Ctrl-V and Delete/Shift-Delete also triggers explorer.exe shutdown), or delete anything (technically I could do it with cmd, but it's getting on my nerves). If anyone had a similar experience before, please post what did you do.
P.S. I'll reinstall Windows in a few days, so it isn't really a life-death issue. Regardless of that, I'd be grateful for any help.

Pretty sure it's a virus. Easy answer, reformat.

error with windows maybe? get a registry cleaner like ccleaner if that doesn't work its a virus. OR you could try going to a previous point via system restore.

Alrighty. I think I'll simply reinstall earlier. Thanks anyway.
