I just got a computer that has some serious malware issues.
It's a Dell Inspiron 9300 running Windows XP.
When I turned it on, a blue "Windows System Restore" box appeared when starting it under the standard mode and said it was repairing and to continue. It kept going and lots of popups appeared, culminating in one saying to "fix" the problems I would have to buy the "rest" of the program, though I shut it down before it got further than that. The result was that the desktop went black and essentially nothing really worked on the computer, even in safe mode. When I restarted it into safe mode, it wouldn't even allow me to access the network setup.
I ran Malwarebytes' Anti-Malware, which found a few infections and claimed to fix it. However, the black desktop still won't be relieved and I couldn't see the programs in the start menu.
I ran the command:
attrib -h -s *.* /S /D
in the C:\ command line prompt, which lead me to see some things in the Start > All Programs tab (like Acessories, Malwarebytes, Dell Programs), but still not the majority of the programs that were installed on the computer.
Any advice on the next steps would be of great help to try and recover my PC.
I'm taking a risk by using a USB stick to transfer some programs to the infected computer and like I said, there's no access to the internet from the infected one, so keep that in mind.
