**Using an HP Pavilion dv6700 CTO Entertainment Notebook running Windows Vista (from a friend who bought it from a friend without the Owner’s Manual, Vista CD, or anything else). Appears to have been infected with rootkit and Trojan horses by the first user.
1. I already followed Select Real Security’s “Malware Removal Guide for Windows.”
2. I used Windows Malicious Software Removal Tool to remove a rootkit and Trojan horses.
3. I then repaired the internet connection using the Farbar Service Scanner.
4. I installed AVG immediately and cleaned the remaining viruses, and I used CCleaner to remove the remaining temporary files, etc.
Somewhere in the whole process, the laptop was involuntarily upgraded from Vista to Windows 7 before I got the chance to create any restore point. I DID NOT ever select or see the option for an upgrade.
Now I have the problem of “This copy of Windows is not genuine” with no product key to activate it. Windows Update is working and now the computer has all the latest Windows 7 drivers.
And even though I repaired the internet connectivity, the following devices are not recognized by the system, but some of the correct drivers are supposedly installed and “working properly” in device manager:
CD/DVD Rom drive
VGA (graphics) card
I don’t know if this is due to the Windows 7 upgrade or the long-standing infection that crippled them.
Please help.
1. How did I get upgraded to Windows 7 without my knowledge?
2. All I have is a Windows XP SP3 recovery disc. Should I downgrade?
3. How can I get the laptop to recognize the webcam, CD drive, graphics card, and microphone hardware again without a restore point and with no Vista recovery disc?
