Constant security and anti virus pop-ups from Additional guard and other programs, redirecting to different websites, McAfee disabled and won't run

I am getting many popups that won't go away claiming that my computer is infected with different viruses.  I also have a program on my computer called Additional Guard that I can't get rid of and my McAfee programs have been disabled and I can't run them.  I tried to download updated software from McAfee but it still won't run.  Often times when using IE I am getting redirected to different websites.

When I ran the HiJackThis analyzer I got a message stating: 'For some reason your system denied write access to hosts file.  If any hijacked domains are in this file HiJackThis may not be able to fix this.  If that happens edit the file yourself, to do this click Start, Run, and type: notepad C:\windows\system32\drivers\etc\hosts and press enter.  Find the lines HiJackThis reports and delete them.  Save the file as 'hosts' and reboot."

Please help!!

I have downloaded HiJackThis and here is my log:
