Hi, I have a big problem on my Internet Explorer. It begins to process more time whenever I am browsing the web. I also notice that there is a MyStart Toolbar in it. In addition, MyStart also replaces my homepage. I don’t know how this thing get inside my computer. The last software I installed was a free game sent to me by my cousin. Could it be that a virus or something infects the file?

Please give me some advice in removing MyStart by Incredibar Toolbar on Internet Explorer. I already run a virus scan using my Avast Antivirus but it returns zero result. What else can I do to remove this pesky thing from my computer?
