Good News!!!
I got rid of the patchyoursystem.com crap (I think so)
I followed all your instructions, however I didn't know what you meant by /u/.... etc.
everything else I followed, then I manually deleted the shnlog.exe & all the other processess you listed before & also ALL the hp...tmp files, along with a exe file that had a red circular icon with an exlamation point in it (forgot the name)(I googled these processess before deleting them to make sure they are indeed no good ones) then I went to regedit and made a search for "shnlog", "intmon" and deleted 2 keys that were disguised as paint.exe & another one I don't remember the name, & as soon as I was done with all these things when I started IE it was gone my startpage was back to normal.
Oh and by the way, I used to use Firefox, however I found that it's a bigger drag on the computers memory than IE, everything used to work slower because of it.
Thanks
