Well, I have scoured through these forums trying to find an answer to my problems but have yet to get my laptop back to normal. Some how, I have managed to get infected with something that has taken control of my browser and is stopping me from running any application that helps to rid viruses and malware. I have managed to remove from the registry anything that was loading a file called brastk.exe as well as pointers to av.dat, delself.bat, karna.dat and replaced the infected beep.sys with a fresh copy. Now, these files no longer appear on reboot, nor do they appear in the registry anymore, but my browser still will not let me navigate to sites that will help to remove infections or even the windows update site. If I google something and then click on the link, either another browser window opens with new search results or a window opens with nothing in the window. Also, I can not install or run applications like Anti-Malware, SuperAntiSpyware, Combofix, HijackThis, etc. They appear to start but then nothing happens. The machine does boot up, be it Safe Mode, Safe Mode with Networking, or a Normal Boot and the symptoms are exhibited in all boot modes. Can some one help me sort this out or do I need to do a complete reinstall to fix this? Any and all help greatly appreciated. Thanks in advance. - Dan P.S. OS is Windows XP Pro with SP3 P.S.S I have tried following the Updated 8-step Viruses/Spyware/Malware Preliminary Removal Instructions but as stated above, I can't get the applications to install or run.
