I work as a consultant and clean malware all the time. My standard M.O. is to run Malwarebytes first and if that doesn't fix an infection, run ComboFix. So I am at fault for ignoring the warnings. Here's my story....
A user complains his desktop icons are missing. I remote in and see hard disk error popups (fake) and run Malwarebytes, which finds and removed a bunch of things, PC seems OK after reboot.
The following day, issue returns (or at least this is when it was reported to me). Seeing as how MWB failed to fully clean the infection, it was time for the big guns. I disabled AV and ran a fresh version of ComboFix. The blue command window came up as normal with a blinking cursor, but remained like that for 10-15 mins. I tried to cancel it, terminate it, reboot windows... nothing worked I could not do anything on the PC (it appeared frozen except for the still-blinking cursor, and buttons depress when clicked but do nothing). The PC was powered down by holding down the button. Now the PC will not boot. The POST splash screen comes up, it sees the HDD, then instead of booting into Windows, it just goes to a blank, black screen with a blinking cursor in the top left. I tried boot disks without luck. There was no XP setup disk onsite to use.
I tried the Windows XP Pro setup disk, which is found and the screen displays "Press any key to boot from CD..." Pressing any key seems to work as the counting dots stop counting and the boot order does not go to the hard disk. However the XP disk never loads, it just stops there at "Press any key to boot from CD..."
Is there hope for me? I am having the PC overnighted to my office so I can get my hands on it. What should I try, since I've already tried everything I can think of.
BIOS DTS Self-Test passed
Tried new keyboard, same issue
