Hello. The past couple days I have been suffering from frequent "blue screen" crashes (OS is Windows 7), Google links re-directing to ad sites, and general slowness in my Internet Explorer 8. I've used Search & Destroy, AdAware, and Malwarebytes to scan the computer, but they never were able to delete Click.Giftload. They did in Safe Mode, but after rebooting and scanning again it was back.

I've tried to run DDS so I can provide a log, but when I try to save it/run it, my computer keeps saying it needs permission from the administrator (which I am), and keeps popping up when I hit "Try Again". My McAffe also pops up at the same time, saying it has deleted a Trojan. I've uploaded a screenshot of the issue.

Any help will be appreciated
