Hello. I found this thread on your forums:
I am having the same issues as this person. I have Norton 2007 and have ran a full system scan in both normal and safe modes but nothing has been found. My problem started at approx 1240pm yesterday when my Norton said it detected and stopped a downloader. this happened several times and then my screen started to fill with "Symantec Proxy Email" pop-ups for random emails. There are like 100 per minute at least.
I found a process running called "mrofinu1000512.exe" and killed it but my problem didnt stop. I looked in my system32 folder and found that file was created at approx 1240 and was able to delete it. But I also found another file called xpdx.sys which I cannot delete. I've rebooted in safe mode, and command prompt and still cannot delete. I went through my registry and deleted a couple keys for "xpdx" in run set but couldnt delete all of the keys for it. I did find and removed the keys for "mrofinu1000512.exe"
These steps have not fixed my problem and since Norton is not finding anything wrong I dont event know what virus my computer has caught. I am currently not at home and have never used software such as hijack this.... Are these safe? free? Please any help is greatly appreciated.
