Hi, after all these steps, my Win7 Starter still auto shutdown when booting in normal mode. Only when using safe mode it doesn't immediately turn off on its own. So where's the problem though if it's not the adware, malware, or virus?

@Predated_Ash: If your system is clean, then try the following:
1. Perform a clean boot and if your system works normally (in clean boot mode), re-enable one-by-one the disabled startup programs and services until you find out which one causes the problem.
2. Use the CPUID HWMonitor utility and ensure that your system is not overheated, otherwise clean it from dust
3. Diagnose the HDD for errors
4. Diagnose the Memory (RAM) for problems.

Hi Lakonst, You have written a thorough article. But I think my problem is different. I have tried upgrading my Toshiba P75 PC on Win 8.1 by installing Crucial memory chips, but my PC initially appears to run normally, then it crashes and reboots itself after a "PC Ran Into a Problem and Needs To Restart" due to numerous different error messages such as "Pen_List_Corrupt" and "Kmode_Exception_Not_Handled". When I remove the upgrade, the PC runs fine. I've run Verifier. Any suggestions would be appreciated, Thank you, Dunechair

I'm using Avast,….which just picked up a 'Malware-gen', a 'DH' (whatever that is), and a 'Shortcut-inf [Trj]'. This AFTER I'd run the MWB scan!?!
I don't hold much hope that it's fixed my problem, though.

All done (but 'deploy.static.akamaitechnologies' is still sucking my bandwidth!!). I think I'm going to have to make time to do the 'clean boot and disable…'!
Thanks for your help.

Thanks Lakonst,
It's just occurred to me that maybe i know which program(s) are running deploy.static.akamaitechnologies: whichever browser that I'm trying to use.
deploy.static.akamaitechnologies shows as multiple processes of the browser software (ie Chrome.exe) in the task manager. But, if I try to 'end' any of the processes, the whole browser closes. However, it does reveal its true identity in the 'Networking' window of the Resource Monitor (that's how i identified it).
Does this mean that it has to be a browser plug-in? But, if so, the only enabled plug-in that i can see is 'Google Docs'. Is it possible that it's a hidden plug in, on all the browsers?
Thanks for your help.

@Stig: Do you use a Symantec product? If so, then try to remove it and see if this helps. If not, then
1. Run AdwCleaner, JRT and perform a full scan with Malwarebytes Antimalware and ESET Online Scanner.
2. Use CCleaner and disable all Scheduled tasks.
Stig
January 10, 2017 @ 12:36 pm
Symantec? Not that I'm aware. I've just entered it in the 'search programs and files' box, and nothing came up.
I've done everything (Adw, JRT, + ESET + regularly use Ccleaner) EXCEPT install the malwarebytes program (swapping my current av, to this, will take time).
Which scheduled tasks? I don't think that I have any set. The only thing that I (knowingly) allow to happen automatically is update checks: windows, AV, firewall, web browsers etc. (But, I try not to let anything download/install without my permission.)

@Stig: Install and run MalwareBytes once and then uninstall it. Which AV are you using?
Stig
January 2, 2017 @ 2:48 pm
Thanks, I'll give it a try, when i have some time (and I'm feeling brave!).
BTW, I've found a good 'clean boot' walk-through, for anyone one else who needs to do the same:

Hi Lakonst, Thanks for these great guides.
2 questions:
I've just read that Malwarebytes 3 is now a different kind of program, compared to previous versions. Apparently it's now a full AV suite designed to compete with the big names. Does this mean that I'd need to uninstall (or at least disable) my current AV, when installing it?
My problem is that "deploy.static.akamaitechnologies" keeps running, and totally sapping my download speed, whenever I try and watch adobe streaming content, on any browser.
I've tried the first 3 steps, in this guide. Some possible, and false positive, infections were discovered. But, this 'deploy.static.akamaitechnologies' problem still remains!
Any advice?
lakonst
January 2, 2017 @ 12:10 pm
@Stig: Hi there…1. The Malwarebytes 3 is a full Antivirus and Antimalware security program. So, it is better to uninstall the current AV program.
2. Akamai is a Content Delivery Network used by many companies for internet content. To find out which program or service causes the traffic problem, perform a clean boot and disable all non Microsoft services and programs at Windows startup. Reboot your computer and see if the "deploy.static.akamaitechnologies" is still running. If not, then enable one by one all the disabled services and reboot until you find out which one causes the traffic problem.
