This is on my Mum's Sony Vaio laptop, she got a warning that looked like it was from AVG (free version was installed), telling her that some program had to be installed to clean an infection. After that the computer became unresponsive and once rebooted, AVG kept finding viruses upon running a full scan. I un-installed AVG and installed MSE, which seemed to take care of all the 'normal' viruses, but I keep getting a Windows crash error reporting message saying that the Generic Host Process for Win32 Services has crashed. After running combofix, DDS and GMER it seems that the laptop is infected with a rootkit.
Really hope you guys can help me remove it, and many thanks for any help in advance.
