Nasty redirect hollowed out process, files attached.


Recommended Posts

I have recently been infected with a malware that redirects your webpage to other pages usually while visiting pages on Ebay. 

I discovered that this is due to a hollowed out ntdll.dll process while scanning with zemana anti malware. It tries to remove the process and then it reappears. 

Tried rkill, tdsskiller, kaspersky tdsskiller and zemana anti malware. Only Zemana discovers the harmful process, tries to remove it, but it reappears. 

As a last resort, I wiped the hard drive and re-installed windows. After about 1 hour, the infection reappears. 

Thanks for your help.

It redirects in Chrome and firefox. Seems to only redirect when visiting Ebay. Testing internet explorer as we speak. 

So the hollow process isn't causing this?

Seems the bug also appears on another pc I reformatted last night. Maybe it's attached to extensions in Chrome?

I don't think hollow process is causing this.

Doesn't seem to appear in internet explorer, so it looks more like a firefox/chrome redirect malware. 

Do you have a home router/modem?

There are several possible scenarios for redirecting malware (if this is caused by malware) to survive system reinstall.

1) Infected router --> How to reset it - setuprouter.com/networking/how-to-reset-your-router/

2) For Chrome it can be synchronized back when you log into your Google account.

3) For Firefox, I am not sure if it is possible unless you import data from already infected Chrome.

4) Install uBlock extension, perhaps it helps stopping the problem - https://www.ublock.org/

 

What I would do is the first and fourth step first.
