I have been on the "Am I Infected?" section, getting very nice help from Gunto and trying to clean up my machine. Here is my original problem:
I'm running a HP G62 laptop with Windows 7. I let it update itself till now, not sure if I missed anything.
Recently, one email recipient notified me that she had received some spam (about zeronareviews.com)on 4 occasions over a couple of weeks from a hotmail address with a random code prefix (not my normal gmail address, though that might be where it acquired the contact, I guess) but which came under my name.
I tried to immediately run Microsoft Security Essentials full scan, and it would not update, and gave me an error code (the same as the Firewall code, I think, but it's changed now). When I checked my Windows Firewall, I get error code 80070424.
I downloaded the latest updates manually from the MS website and ran a full scan with MSE. It found:
They were quarantined then removed.
But I still have the same issues, still can't switch the Firewall on, and Security Essentials now gives me the following error code when I attempt to update: 0x80240022. Google is now asking me to go through a captcha entry when I search. The entries on here that I find seem to involve specific case by case approaches rather than a general fix, and though there is a page of instructions on what to do before posting re a virus, one step is to turn on the Firewall, which is part of my problem. Please excuse me if there is something obvious I have missed.
Any help very gratefully appreciated.
The only thing to add to that is I now realise that Windows Defender isn't working either, and has the same error code as the Firewall - 80070424
As per instrucitons, I downloaded and ran TDSS, Malwarebytes, AdwCleaner and Roguekiller first. It was established at that point that I was infected with Zero Access.
I then ran SuperAnti-spyware, ESET, and JRT. I am assured that Zero Access is the only thing of note remaining.
I still have the same issues regarding the error codes, and Google frequently asks me to fill in a captcha box before processing a search query, as if traffic from my network is suspicious. I operate from home, and this is the only PC on my WLAN.
Thanks in advance for any help.
