Hi Charlie, it started earlier today when I sent a coworker an email. He replied and said he immediately received a spam email with my name on it. I started digging around. Microsoft Security Essentials said nothing. I downloaded Malwarebytes, and while it was scanning, MS Essentials started quarantining trojans in my AppData\Local\Temp folder. I then cleared the Temp folder, with the exception of a file Malwarebytes was apparently using. I reran Malwarebytes, and it identified svchost.exe as being a trojan. That is when I started the current process. Thanks for your help.
