My Windows 7 laptop started giving me a lot of trouble. It began running slower and slower, and multiple instances of dllhost*32.exe began filling the task manager. I tried ending the processes, but they kept multiplying. Eventually, the computer locked up, so I rebooted it in safe mode, and installed Norton security on it. Norton cleared out a whole bunch of malware, which freed up my computer, but the dllhost*32.exe problem still remains. Furthermore, it only affects my computer once it's online. Offline, the problem goes away. Every time I log into my computer, I get error messages from this program called "powershell." I also get the little Norton window saying that Norton blocked an attack by a Trojan.Poweliks virus. A few days ago, I left it online accidentally, and I got a message from Norton saying that it detected, a "suspicious amount of outbound traffic". It told me to run Norton Power Eraser, which apparently did nothing. From what I've read, I think Poweliks uses powershell to run a script that starts multiple instances of dllhost*32.exe, and I don't think Norton is stopping the infection, regardless of the little popup window that I get. If anyone could help, that would be greatly appreciated.
