firstly, I am in China, so google is blocked that makes it impossible to register here or contact you because all your captchas are google captchas. I managed to get a friend to help me make this account.
secondly, because I am in china, if you have any questions about the log files attached please do ask, I have had to install a lot of chinese malware just to get 'clearance' to access their internet services.
Next, I usually have no problems removing malware, in-fact I've even done some manual removals and SYSTEMUSER removals of null value registry keys.
several years ago I encountered some wifi connectivity problems with the wifi device on my computer, after exhaustive work trying to fix it including trying an failing to remove a null value registry key associated with the problem in controlset01 I found that it was a hardware problem, where the wifi device had been fried from overheating (because I opened and closed the laptop in a rush and put it into a suitcase while it still hadn't gone to sleep) It will connect to wifi for a few seconds or minutes but then after loading one URL it immediately goes to limited connectivity. and that's when I got my USB wifi device to replace it and that has worked fine for years.
yesterday, I got a java popup in firefox from china telecom, I could not read it because I don't know chinese (being from the USA), but I was not happy that they could produce that add in my browser and recent scans with my normal antivirus software (viprerescue, tdsskiller and malwarebytes) turned up blank. So I deicided to use adwcleaner (which I had never used before). it found a file called netfilter.sys in windows system32 and I thought "ah ha, that has to be it", so I went along with the removal.
But now both devices are giving me the same error, where they say there was a problem connecting to the wifi and thus have limited connectivity. I ran my normal antimalware and added in roguekiller they found and flagged some net hooks associated with netfilter, and some registry entries for netfilter, so I got rid of them all. I still cannot connect to wifi. I am using a different computer to get online to post this.
after all that I searched for netfilter.sys and found an official microsoft.com page explaining that it may be a network SDK driver supplied with windows 7 based on a linux netfilter device SDK.
So it looks like I may be wrong, it wasn't a virus, but now I can't find an official installer to repair it. I've still got the netfilter.sys in system32/drivers/driverstore.
anyways I have never dealt with this sort of virus before or if it isn't a virus I have never done something this stupid before as to remove a valid file or net hooks, I have no idea how to install replacement net hooks etc.
please help.
