Hi,

 

i've recently encountered an incredibly frustrating problem with a customers pc running Windows 7 64 bit.

 

IE is exhibiting a very strange behaviour, in that it won't let me connect to any site using the https protocol; the browser is showing the usual security error page displayed when a certificate is expired, revoked or self-signed, but without the option to proceed anyway.

 

I suspect this is due to a malware i can't seem to find.

 

I've tried running the following programs:

Malwarebytes

Hitman Pro

Microsoft removal tool

OTL

Hijackthis

Process explorer

Autoruns

Roguekiller

Adwcleaner

Eset online scanner (i stopped the scan before it could finish as it was taking too long and the user had to use the computer)

 

They found and removed several threats but the problem still persist

 

Let me know if i should rerun some of them and post the resulting logs here, attached you can find the log generated by otl quick scan .

 

Thanks in advance 

 

Best regards

Warning: In your original post I can read you used a lot of tools here. Also tools that were specifically developed to be run under supervision of a trained Malware Analyst like me. I really advise you to don't do this anymore in the future, and come to us straight away when your regular anti-malware programs can't solve the problem.
 
1. Please collect as much logfiles as you can from the tools you've used, as mentioned by you in the first post. I would like you to add them as attachments in your next reply.

Good luck! :)

Hi Black_bird,

 

at last we've found how to solve the problem.

 

We had run a microsoft fix it to re-register the internet explorer DLL (link: https://support.microsoft.com/en-us/kb/813444 method 4)

After the fix it IE started to work again.

 

Best regards
