I saw someone had made this post a few days ago, and I am having the same issue. It keeps changing my homepage to the graphic pipeline, and an error icon pops up every now and then saying error, out of stack space...oh, what to do??

a copy of the other post:::


a few days ago I was talking to a few friends in a group chat on msn when one of my friends sent me a message with a link. He insists that he didn't send me the link but, when I clicked on it, it downloaded a file and installed a virus or something. Now everytime I reboot my computer, F-secure pops up letting me know that there is a program trying to change settings to my computer and it wants to log on to the internet and start on the next start up. It also changes my homepage everytime to this graphics Pipeline homepage.
It won't let me open certain programs like the hiJack this or my process explorer or anything like that that could assist me in getting rid of it until I get this message that says, ppcjdgqu runtime error.
after that I can open anything. It also tries to associate my .reg files with this %1.
Don't know what that is. any help would be appreciated.
