I'm was on my computer, and clicked a pop-up that said it was Microsoft. I ended up with a virus, and was unable to get on the internet. A friend said he did a re-install of Windows 7, without removing any of the data from my computer. Since then, my computer has been unbelievably slow and makes a funny double click sound when I boot up. I like to stream music, while working on the computer of just to have it playing in the background. Typically it will just freeze up and stop playing, which as of late is within 5-10 minutes. After I leave the site and return to start the music, it will lock-up again and usually the third time it will kick me off the net. In addition it takes forever for pages to load. I have been searching the net for answers to this problem and have found nothing. I am at my wits end with this, so if anyone can help I will greatly appreciate it.
