We are running on a Windows Vista Ultimate (pretty old) we got it in 2007, I think.
Processor: Intel Core 2 Quad Q6600 @ 2.40 GHz 2.39 GHz
Ram: 4.00 GB
(not sure if any of that helps but just in case)
We hardly ever shut our computer down, just turn the monitor off. Often times, when I turn the monitor back on, there are pop up ads (sometimes explicit and I have children!) and sometimes there will be an audio ad running but no visual.
We use Firefox for online access and 9 times out of 10, the website we type in is not where Firefox takes us.
The computer is running super slow as well.
Any help is much appreciated!
