Boot load unpredictable

[Guest]

[Benjamin]

Hello again Comodo helpers. Sorry for the constant questions 

I've recently infected my computer with a backdoor Trojan while analyzing it (I accidentally ran the Trojan outside my sandbox) I cleaned and disinfected my computer and repaired my registry with Comodo System Cleaner, what I thought was a conclusion actually turned out to create an irritating consequence after disinfection my system.

When Windows boots it sometimes loads really fast and sometimes loads really slow, a few times its also frozen on the welcome screen, I'm not sure how to fix this problem.

I've checked my processes and all seem to be legit.
I've ran a Comodo Anti-virus scan and also an avast scan, clean results.

Please help me troubleshoot this problem, thank you very much for taking the time to read this, I really do appropriate the help you guys give

Do the logs of Windows show it is waiting for something during those long boots? The logs can be found in Event Viewer under Control Panel --> Administrative tools.

[Benjamin]

I've checked the logs. This error repeats what seems over 1000 times

Code:

DCOM got error "The service cannot be started, either because it is disabled or because it has no enabled devices associated with it. " attempting to start the service winmgmt with arguments "" in order to run the server:
{8BC3F05E-D86B-11D0-A075-00C04FB68820}

Besides that, nothing

[EricJH]

I looked up the 8BC3F05E-D86B-11D0-A075-00C04FB68820 string with Regedit on my Win 7 RC system. It refers to Windows Management Instrumentation Service.

Look up that service under Control Panel --> Administrative Tools --> Services and see if it is set to automatically start or whether you see anything particular about its properties.

[Benjamin]

The service was disabled, I set it to auto and enabled it. Thanks

I'm going to restart my computer now  

Edit: The error doesn't show in the logs but my computer still starts slow

[EricJH]

Follow What to do if you're infected - eXPerience Rev.3 to make very sure you are not suffering from any type of infection.

[Benjamin]

Ok I'm going to do that now as that looks like its going to take a while.

I will post my HijackThis log here as making a new topic would get confusing

Talk soon.

Hello again!

I've just finished scanning with the 3 anti-viruses and removed 9 files, 8 tracking cookies and the remaining 1 which was suggested as a serious tracking cookie.

Also, Malwarebytes changed something in my registry to do with Comodo security, I am not able to start the computer normally (I'm in safemode + networking) I'm going to do a complete registry restore again and hopefully that will cure it.

I'm also going to download the tool Bootvis and give that a whack, maybe that might solve some problems.

I will post a hijackthis log when I am able to log in normally.

Edit:

Edit: Fixed, I've reinstalled windows as more problems started to happen and I made a image file of my windows if this problem happens again. I hate reinstalling windows.

Thanks for your help.
