In the last 48 hours.... a dozen or more unpublished posts were deleted from my Blogger account, and I've had my primary e-mail account failing to send out or receive messages for a period of about 6 hours (although I think everything went through eventually). Even more worryingly bizarro, a filter had appeared in the e-mail account that was seemingly intended to direct all messages originating from my own address to the Trash folder (that wasn't what was interfering with my sending or receiving of messages, but it might have caused additional problems later on, since I typically do Cc or Bcc myself on important correspondence - to check what kind of delays are afflicting my e-mail transmission).
And then my computer suddenly CRASHED altogether. And failed to restart for the next several attempts.
And when I did finally get it going again, I found my VPN - which I thought I'd managed to restore to full functionality in the morning - was being blocked again.
I disconnected from the Internet for a good long spell, rebooted and reset everything I could think of, crossed my fingers, and swore profusely.... and after that unfailing ritual, everything (touch wood) seems to be back to rights again.
It is, however, hard not to believe that I have been targeted for some special attention by hackers.
The coup de grace was that the bastards changed my clock as well!
