Computer wont start after removing alureon virus with defender offline

You have a Rootkit. The best advice I can give you is to wipe and do a "Clean" install.
Rootkit - Wikipedia, the free encyclopedia

Your computer has been severely compromised and I wouldn't count on it to be stable by trying to 'fix' the Trojan.

I, personally, don't work with Rootkits, but there are other forums who have 'trained' experts.

stevenbensusan,

I am basically retired, but, give this a try:

On the clean computer, please open: Notepad
Copy/paste all the contents of the quote box below to Notepad (do not copy the word 'Quote').
Save it on the flash drive as: fixlist.txt

start
TDL4: custom:26000022
cmd: bootrec /fixmbr
cmd: bootrec /fixboot
end

Running the script on another computer may cause damage to the Operating System.

Now, in the infected computer, plug in the USB flash drive, and enter System Recovery Options as you did before.

Run FRST again, but this time press the Fix button just once, and wait.

When done, the tool makes a log on the pen drive. This time it is called: Fixlog.txt

Try to boot the computer into normal mode and post back on what happens.

Also, please post Fixlog.txt in your reply.


If the computer still does not boot into Windows, just hang in there, please.

stevenbensusan,

Glad the fixlist worked.

Please run FRST once again, but, this time, download a fresh copy to the Desktop, and run it from there, so we can get the complete log. Also, please check the Addition.txt option.

When done, please provide both reports in your reply.

Also, please go to the TDSSKiller Download
Select the .exe version

Double-click on TDSSKiller.exe to run the program.
