I have Vistas premium home version 64 bit with IE8 and service pack 2. Yesterday I got a red alert from Microsoft Security Essentials saying that all kinds of things were turned off in security essentials so I found out how to turn it all on. I also scanned with updated Malwarebytes free version and it found things which I removed. I don't seem to be getting the red warning sign anymore but the computer is terribly painfully slow and I keep getting these notices on the bottom of my screen saying that a certain percent of some file is downloading and it's weird stuff. It asks me if I want to run or save the file and I just click cancel but these strange files keep appearing as if they are downloading, Stuff like s3-us-west-2.amazonaws.com, they're unknown files, some say something about a video etc. When I click on Internet Explorer it takes forever to display my home page and when I go to google to search it really hangs for a long time and in Outlook it takes ages to go to an e-mail that I've clicked on and stuff like that. Please advise me on what to do to start the process of straightening things out. Thanks!
