There are some discussions about this on the web:
So far I have taken the following measures:
- Changed password
- Turned off my vacation responder
- Cleared my vacation message and signature
- Turned on "Mail Goggle" feature in Google Labs
(BTW, Merry Christmas and Happy New Year to you all!)
---
Some technical information here:
- My GMail account was accessed from another IP

- My vacation responder message and signature were all changed to that SPAM message
- I used Google Chrome to open GMail
- I was running Avast! On-site virus scanner 4.8
- Details about that IP (124.118.178.170):
