I have 2 of these this morning. They are similar but different. I will post them as 2 different threads.
The first problem is a WIndows 7 desktop computer. I cannot get to several websites - notably Eset's online scanner is a problem. I can download Revo Uninstaller, but I can't install it. The search provider is AVG Secure . I cannot uninstall the AVG toolbar. I was able to Install Malwarebytes from a USB Flashdrive, but I could not download it at all. The Cnet download button does not respond.
I have run the Windows Defender Offline scanner. It did find and correct some problems. Superantispyware found some problems, as did Malwarebytes. The virus or at least its effects are still with me.
TDSS Killer found nothing.
Resetting IE did not improve the situation.
I tried to run Hiren's boot CD, and it reported a PXE stack problem - would not boot. The CD actually worked last week on another problem.
I am out of bullets at this point. What else can I try to kill this virus?
