First and foremost delete all the files you downloaded, make sure they're completely deleted and not in the recycling bin. Next, you want to open up processes in the task manager and kill any and all process that are related to the pum.userwload process . Then boot up your computer in safe mode, go to your registry, look for the entry(ies) named anything you don't recall downloading, has the same name as the files you download, is named pum.userwload, etc. You might have screwed yourself over, I recommend getting to a safe computer and change ALL important passwords (e Mail, banking passwords, etc.) If you can't remove the virus, you're best bet is to format and re install your OS. If it comes to that, don't back anything up on a flash drive, you may end up giving the formatted computer the virus again.
