I am running Windows Vista Home Basic with Service Pack 1. A few days ago my computer started to become really unresponsive to the point where it is almost unusable whenever I am doing something that involves uploading or downloading things. The task manager shows a big spike in cpu usage when I am using the internet and the fans spin up really loud, but it shows that almost 1 GB of RAM is unused so I don't think that is the issue. For example when I am watching a video on Youtube, the video will be choppy until the entire video is cached on my computer. Even just downloading an attachment from my email causes the mouse to stop moving fluidly and jump around the screen and it takes a long time to switch between screens. However whenever the download is finished, the problem disappears. It does not appear to be an issue with the browser because it occurs regardless of whether I am in Firefox, Chrome, or Internet Explorer. I have scanned my computer with Spyware Doctor, ZoneAlarm antivirus and antispyware (which is also my firewall), and Avert Stinger, with the most up to date definitions and all have come up clean. The only change I have made recently is installing SafeConnect, but I can't tell if that is the problem because they don't let you on the internet if it isn't installed.
