@Mame,
Smiles, watch out for Mame, she is a mad cook... really, she has some fascinating threads about cooking in mining camps for a crowd of hungry people. We've met each other. Good woman, except she doesn't like anchovies.
I don't know enough to help, especially re viruses. Somebody smarter on all this than the rest of us will come along to help.
I've been at a2k, what, approaching nine years, and have never seen a question like this pan out to be an a2k fault.
On cookies and a2k, if you deny all cookies, then you will have to log in -
well, don't trust me. I used to hand pick cookies (now there was a waste of time) and based on some discussion stopped bothering with that.
But, I am guessing you can clear all cookies and then check back in and just get the a2k cookie anew.
