A few days ago, I went to shut down my laptop and discovered that Internet Explorer 8 had several tabs up. They were running in the background, completely invisible to me unless I looked in Task Manager. IE would open from 5-8 tabs on its own, all spam (the most common avulu.com), and the tabs would persist until IE crashed. To solve this problem, I ran a scan with Emsisoft Anti-Malware. It detected only one malicious file and several other low-risk registry keys/files, and I deleted them all without thinking twice.
I believe this has solved the IE virus, as I have seen no more tabs come up in Task Manager, but now I'm having issues with RunDLL. When the tabs were coming up, sometimes an error would pop up saying RunDLL had stopped working, but now when I boot my laptop there is a message saying that a file is being removed (I wasn't fast enough to read it properly, but I believe it's in the AppData\Roaming location), and when I log into my user, two errors popped up:
"Error loading C:\Users\Editor\AppData\Roaming\shtomn.dll
The specified module could not be found."
The second message is identical, but it has "usypap.dll" at the end instead. I have two users on my laptop and this is only happening on the one, "Editor". I am running Windows Vista, version 6.0, system pack 1. I haven't noticed any other adverse effects but am concerned about what the RunDLL errors mean and if they're the product of a malicious file. Any help is appreciated!
