Before I review your OTL logs, I want you to run Combofix fix. Apparently, you have tdx.sys file missing from C:\Windows\System32\drivers folder, so we'll try to put it there... 1. Please open Notepad Click Start , then Run Type notepad .exe in the Run Box Click OK Windows Vista/7 users: click Start, in "Start search" type notepad and press Enter. 2. Now copy/paste the entire content of the codebox below into the Notepad window: Code: FCopy:: C:\Windows\winsxs\x86_microsoft-windows-tdi-over-tcpip_31bf3856ad364e35_6.1.7600.16385_none_ea141e6f3d693e28\tdx.sys | C:\Windows\System32\drivers\tdx.sys 3. Save the above as CFScript.txt 4. Close/disable all anti virus and anti malware programs again, so they do not interfere with the running of ComboFix. 5. Then drag the CFScript.txt into ComboFix.exe as depicted in the animation below. This will start ComboFix again. 6. After reboot, (in case it asks to reboot), please post the following reports/logs into your next reply: Combofix.txt When Combofix is done, re-run same commands as you did in your reply #18 and let me know, if all of them went through this time. If they did, check your internet connection.
