I just did a recovery on my puter . I was getting these unresponsive sripts putting a hold on everything I did , everything would freeze up and i expect that it will do it again but have never figured out why , Every click of my mouse it would freeze for an undetermined amount of time. I have windows xp and use firefox as web browser however I changed to firefox 2 years ago when this kept happening in internet Explorer. I am not all that tech savy, but maybe if someone can tell me what this is and what to do about it I can prevent this in the future. I have another computer that is locked up with this mess. I had both computers synched with a rROKU device so that I could watch movies on my much bigger flat screen. I didn't know that my computers were sharing more than a movie link.
