============================================
These are all different malware infections. Unfortunately "Avg giving message object hidden by rootkit technique" doesn't tell me enough to act on..
Since you can't launch a browser and only get into Safe Mode, it would be best if your did a reformat/reinstall.
I don't have enough information to advise you otherwise- except to bring you attention to the fact that your passwords may have been compromised as can be any other information on the system. Don't just shut down and give up. If someone does have your information, they may attempt to use it.
