Firefox opening ads randomly

[raz1337]

A few days ago I began having issues with Firefox running slowly, opening random tabs to websites with ads and redirecting links I clicked to spam search engines.

So, I've ran both sets of steps, the general and Windows 7.

I'm on Windows 7 Home Premium. Here are my logs.

Please download ComboFix to your desktop and run it. Do not do anything while it runs. Attach the log when it is finished.

Is the ComboFix.log meant to be in the root directory of the C: drive? I'm not seeing any logs there or on the desktop. I see a folder called "32788R22FWJFW" that just brings me to the list of all drives and a folder called Qoobox that was just created.

The log should be at C:\Combofix.txt.

There is no log there. The program runs, and the progress bar reaches the end, then the program closes and disappears with no logs.

Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator).Make sure that you watch for the license agreement for TrendMicro HijackThis and click on the Accept button TWICE to accept ( yes twice ).

Then attach the below logs:
* C:\MGlogs.zip

I'm trying to do that. I was browsing the internet, and had a several tabs open, then went to go to this forum post, and while I was going through the links, another tab opened that I wasn't paying attention to and installed something resembling Security Shield. Now whenever I try go going to the desktop or opening anything, this "Security Shield" says the file I try to use is infected with a random virus or malware.

I'm not trusting those popups, but that made it difficult. I had to hard reboot the laptop. It wouldn't let me do almost anything. I rebooted into Safe Mode and ran MBAM once more, it found a Trojan Dropped and removed it. I've rebooted now and it's letting me finally run the MGTools again. Here are the logs for that.

I'm just really wanted to avoid a reformat.
