Can someone help me out here?
My computer seems to be full of spam and I don't know why. On this site, sometimes in posts, there are words that are underlined, and when I hover my mouse over the word, a window drops down and its a link to a site selling stuff.
Sometimes when I click the link to a thread here, another page opens up and it takes me to a spam site.
I have never have spam on this computer before - a few weeks ago I tried to download Microsoft Office 2010 or something, which I needed in order to view a file I had downloaded from my karate website. It seemed to have added other programs, and while I deleted it and the other programs, they still show up.
When I click on the Firefox button, two windows open up, instead of the one, and a window pops up in each one saying that an installation of something has finished, and I can't do anything until I click 'finish' and the window disappears, and only then can I visit this forum, or any other forum.
I know my computer obviously needs a clean out, but I have no idea how to do it - I want to keep all my passwords and bookmarked sites, including the sites I have in my drop down window at the top of the screen. How do I manage to get rid of this spam shit without getting rid of those?
