I found this SearchNU crapware on my pc this morning, and removed it via the Control Panel. I also found some unwanted emoticon mess for my messenger on my desktop too. Removal via the Control Panel worked fine for me. I don't know how that garbage got on my computer, because it wasn't there last night. I ran CCleaner for good measure and also a full antivirus scan. I reset my homepage too.

I found out that the most likely culprit was the JZip my daughter downloaded when she visited my home on Thursday. I never noticed it, and it hadn't switched my homepage at that point.

For those of you who are infected By SearchNu, these steps should help you remove it fully:

1. Open Firefox. Type about:addons into your address bar, press Enter. Click on Extensions, then Remove any SearchNu or other unwanted toolbars and extensions. Restart Firefox.
2. Install https://addons.mozilla.org/en-US/firefox/addon/searchreset/
3. Download and Install MalwareBytes Anti-Malware, run a full Scan. http://www.malwarebytes.org/. This helps check that there are no viruses on your computer causing issues. You can uninstall this program after you clean off any infections.

This should help fully remove SearchNu. Another technique that you can do is to do a Full Firefox Reset. Refresh Firefox - reset add-ons and settings

I also found some program called JZip on my computer. It is associated with bandoo media. I got rid of it as well. So far, no more nasties.

-Tylerdowner - Thanks for this info. Checked it out, but the method I mentioned seems to have done the trick, will none-the-less, I am sure, find use for it in the future. By-the.way Searchnu never came up as a virus nor as malware on my anti-viral software/s, nor did it appear to be tracking, it simple presented itself as a search engine option. However, it appeared after a harddrive re-install, together with AVG (search and secure add-ons), both of which were at no time clicked on by me during the installation. The bit that really makes me throw a wobbly is that FF was downloaded from mozilla.org! It is also a first after many, many years! Thanks for your assistance.
