What email client you using Frau?

I've found the filters on thunderbird (as an example) to be quite good at flagging junk and dealing with it for me. Then again I very rarely give out my isp email, that's what hotmail is for lol.
Like you, I get some stuff delivered from an old account that I never got round to deleting, but pretty much anything that's not already in my contact list gets automatically moved to a temporary folder so I can glance over it before erasing.

I used to get all hot and bothered about pc security (true there are some things to watch out for still) but I never found anything worse than tracking cookies, despite having boot scans, spybot, adware, 3rd party firewall and AV and some other stuff. I put this down to my browsing and downloading habits more than anything else tbh.

What I currently use - router, os firewall, avast av free, firefox no script plugin, thunderbird email client, occasionally I'll run spybot or something similar to see if there's anything to catch.


EDIT:
@ Vendor, realtime scanning - nod32 and avast both seem to do this with web traffic and email
