I am new to this forum. Recently my computer started getting wierd attacks from various trojans, but I think that all of them were blocked by norton internet security, microsoft anti-spyware and spybot S & D. But still whenever I open a new internet explorer window or a new page an annoying window of aurora from ABI network comes up and a norton security alert for the file "qaltpifvpk.exe" pops up. I always block all connections but the thing just keeps coming back. I located the file in the windows folder and deleted it but it keeps coming back. Also, whenever I stream a video from within internet explorer, it shuts down. Also, my google and all the other search engines are messed up, whenever I search for anything the first page is always full of ads for other websites and car insurance.
Please help me
