The download link takes me to a page that no longer works! I have been trying to get Baidu Antivirus for the past several months,.. with NO success!! :-( ~ Also, Baidu's website doesn't work anymore either.. I used to have the Baidu A.V. program on my computer a year or so ago. I switched to 360 Security for some stupid reason and uninstalled Baidu at that point in time.. I'm so sorry that I did because like i said, I can't find a way to get Baidu again and that really sucks because i thought it was an awesome AV program. I was also using the Baidu Browser and that too, is nearly impossible to find again as well. If ANYONE knows where I can get these Baidu products again, please,-> PLEASE!! -> send me the link,.. I would greatly appreciate it!!! ~> D.F.E.-Chicago, Illinois.
