My office PC recent history

Finally I delete the Panda Titanium antivirus program as I found it always update and update, never stopping. So finally I reinstall the Norton antivirus again, but it also make me sick again as the LiveUpdate not working, I reinstall and reinstall, cannot work. So today I try to uninstall the Norton Antivirus program again, try to reboot, reinstall again, these day, may be I just logon to internet, this time it working again, so happy again. Oh, my Microsoft Outlook also not working properly that day, can sent but cannot received. So I try to reinstall and repair Microsoft Office, it work again, so good. So happy today that these two headache program work again
