My laptop has been having several issues lately. The most obvious so far has been the desktop icons rearranging upon restarting Windows and my antivirus finding trojans. Microsoft Security Essentials has detected several variants of Sirefef. It has removed them only to have them return days later. Vcaredrix and Alureon have also been detected and removed by Microsoft Security Essentials. Any help removing these threats for good would be appreciated as I need this laptop for school. I will now post the logs requested in the 5 step removal thread. Once again, any help or advice would be appreciated and I thank you in advance.
