The problem from Norton it is ranked to low. I use Ccleaner which got a ranking of 9.5 and system mechanic which got a 9 where norton got a 4 those two work together reasonably well. If spybot and Malware don't work together then I will use your advice, Instead of microsoft security essentials or windows defender I use macafee. With this I cleaned my system and it seems to be working right now.

Spybot and Malwarebytes works fine, all you need to do, is to run "immunization" again on Spybot, after Malwarebytes "fixed" hosts file, altered by Spybot. That's the only "conflict" I ever seen between them. So don't hesitate to install both.

Windows has never been "idiot proof", there has always been viruses and malicious software ever since the internet was created. That's why security companies like Norton and McAfee have become multi-million dollar corporations. It's up to the user to be aware and to take precautions that prevent these sorts of things from getting into their systems. I have been hanging around the net since the very early days, and I think in all that time I've only been hit by 2 viruses, once that I recall because of a porn site I visited, and have never had any sort of adware issues. That's because I pay attention to what goes on my system and take some very basic precautions. You can't blame Windows for your own carelessness, the fault is entirely with you.

It sounds like I was talking the installation of the software. Every one I try to install tries to get me to install something else. I use to install back then it would install what it said it was installing where all you hac to do is press next to install it. Now days every time you install something the installation program tries to install something you probably have a copy of like a flash player, a anti virus program, an installation program, a million games, lame discount package when you can't afford to shop on the internet, or I'm not talking about the advice on this post but there is usually a disk optimization program that will tell you what is wrong with your computer but will not fix it when you have system mechanic. At this point I realized I needed more.

Looks like you are not clean of stuff... as the text you quoted is not part of what is written above.

Good luck in your cleaning process, as you are not completely clean yet. You may have to take some drastic measures to remove these things it appears.

And everyone of them that does gives you the option to not install anything extra. So if you pay attention to what you're doing, then you won't get your system filled with garbage. And yes, I don't know where all that crap after "by Plus-HD-1.3" came from. Certainly not from my post. You might be better off just formatting your drive and starting from scratch again.

I agree it appears a BHO is also installed, and god knows what else that likely attempted to inject the img tag into the URL.

I believe I recommended this before but you're likelyi going to have to nuke the computer from orbit and format the thing. It looks unsalvagable.

Just install Microsoft Security Essentials first before ANYTHING ELSE once you reformat.

same here, but I use Chrome.

I also use Firefox on Windows 8 and I did run into a problem with adware and browser hijackers. It took me about a month before I decided I couldn't repair it with Malwarebytes and decided to do a "Windows Refresh". This refresh is NOT a hard drive reformat. It preserved my personal files in the "my documents" folder and its subfolders. It did delete Firefox and Thunderbird, and all of the email I had archived to my hard drive, and every application I had installed from CD or over the net.

Since a reformat of the hard drive is so hard on your private files I think it best to try a "Refresh" before a full reformat.

I feel confident that the problem I ran into was not because of Firefox, but because of some freeware I installed, perhaps even something that was additionally and optionally installable from something I wanted to install.

You have to be very careful about your responses to queries during installation of apps, and you have to be very careful about the reliability of those websites offering freeware.
