My friend gave me an old laptop he didn't want anymore. It's an Aspire 5251 with Windows 7 Home Premium 64 bit on it. It turns out to be infected with the Trojan:DOS/Alureon.A virus and I can't seem to remove it. I've downloaded the Microsoft Defender Offline tool and done a Full Scan, but it found nothing. If I go to Safe Mode, I can't find the virus running in the processes, but once I go back to normal Windows, MSE again finds the virus and can't remove it. I have been trying to restore the machine to factory specs, but the Acer eRecovery Management doesn't seem to be working. Alt + F10 at start up does nothing, and if I use the program from within windows, it just reboots back to Windows again, never performing the restoration. Of course it's an old laptop, no warranty, and my friend didn't give me any restoration disks. I have thought of using an old Windows XP Pro disk and license I have, but the HDD in the laptop is SATA and my XP Pro is pre-SP3 (maybe even pre-SP2), and therefore cannot see a SATA drive without RAID drivers which (as far as I know) can only be installed from an Internal Floppy drive which the laptop does not have. In addition, I don't know how I would get XP drivers for the laptops internal hardware. I need a real guru to help me out with this conundrum, any takers?
