Like many others , I have had a problem with the certified search toolbar and hijacking of my home page. I took two days to 'fix' the certified toolbar issue with various methods found on a few forums, including the use of malwarebytes.
Two nights ago I was able to use the internet for about an hour or so, then all of a sudden it dropped out. I thought maybe it was a problem with my modem as the ADSL light was flashing instead of being constant, and I was not able to use other devices with it either.
Yesterday, I have been able to get the modem working for other devices, but on my desk top (using Windows 7) I was constantly receiving the error message "Windows could not automatically detect this network's proxy settings". The desk top is connected by ethernet cable.
Enquiries with my network provider and some talking through with their technical support reveal that my network interface card (NIC) driver is no longer present on my computer.
I am not sure what to do next. Will a system restore fix this? I backed up and created a restore point yesterday (before the issue was seemingly resolved).
I have Norton Internet Security (2012) but it did not pick up anything, and still thinks my system is fine.
Reading a forum on www.bleepingcomputer.com, I found someone with a similar issue. I followed the steps of going to Device Manager, Show Hidden Devices, and found that an alert (little black arrow pointing downwards) was displayed next to several items in the non-plug and play drivers section under the Network Adaptors. One read "NSI proxy service driver" - as I knew I was having problems with the proxy service, I uninstalled this and hoped for the best.
The computer asked for a reboot, and I was actually going to reinstall it after my computer restarted. However, upon start up, my internet connection was working again and the NSI proxy service driver is gone...
I'm no computer genuis, and probably shouldn't have fiddled with these things that I know nothing about, however, it has fixed the issue at least for now!
Don't know if I can expect any further issues, or if there are any further underlying viruses/malware/who-knows-what.
I am still reluctant to trust my internet security, and don't know if what I've done in Device Manager will cause problems further on. There were also some other items which had the alert (little black arrow) beside them on Device Manager.
I haven't read of anyone else having this issue post certified toolbar. Also, how can I tell if I've completely erradicated the problem? A malwarebytes scan this morning said all was clear, but who knows?
Thanks for any advice.
Also, I ran your DDS tool, but only one notepad report came up. Ran it again just to make sure and that's what it did again, so I only have the 'attach' file.
