Windows 7: No network access, unidentified network error

No network access, unidentified network error

Hi everyone. A few days ago my computer was infected with OpenCloudSecurity spyware and after multiple virus/spyware scans I finally got rid of it. Unfortunately sometime during this my Toshiba Satellite laptop stopped connecting to my WiFi. I know it's not the router or modem because my phone and my brothers laptop (the one I'm using now) still connect fine. I even tried connecting it directly to the modem. I've searched up and down on different forums on the net for fixes and tried many of them unfortunately to no avail. Usually when this stuff happened I would just restore my system. Upon trying, to my disappointment: no restore points! Damn! I tried fixing my registry with WinASO. Rescanned with my virus scanners. Disabled and Re-enabled the Network card. Reset the ipconfig setting under command prompt. I'm at a loss at this point and it's been going on a week that it hasn't connected. If anyone could help me you'd be a life saver. Thanks a bunch.

P.S. - Not sure if this helps but here's my copy pasta'd ipconfig settings:

Welcome to SF,

Try resetting both TCP/IP and Winsock:
Click on Start=> All Programs => Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log press enter
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog press enter
Restart the computer after.

HotMiizii,
Welcome to SevenForums,

If the netsh commands don't solve your problem, there is the possibility that you have an obnoxious piece of malware which can only be rooted out by a standalone mover.

If that be the case, then here is the solution:
PUT SYSTEM SWEEPER ON A USB STICK
System Sweeper, https://connect.microsoft.com/systemsweeper, allows you to start an infected PC and perform an offline scan to identify and remove viruses, rootkits and other advanced malware. System Sweeper is a free standalone, bootable malware and virus remover from Microsoft.

Safety Scanner, Microsoft Safety Scanner - Antivirus | Remove Spyware, Malware, Viruses Free, is free, downloadable, provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.

If the target computer has a working internet connection, then you may prefer to use the Safety Scanner.

NOTE: A fine tutorial on the System Sweeper is:
How to use the Microsoft Standalone System Sweeper


Download System Sweeper (about 576 kB):
https://connect.microsoft.com/systemsweeper

Insert 256 MB or larger USB stick into a usb port.
Run the downloaded program--mssstool64.exe or mssstool32.exe
Choose the option to install to USB.
Caution: The install program will format the usb stick.

The install program will download about 200 mB more.
After the install is finished, leave the stick in the usb slot.

Run the program you downloaded once again.
This 2nd run, and any subsequent runs, will download the very latest anti-virus definitions (about 60 mB).

To keep System Sweeper up-to-date, simply reinsert the usb stick and run the installation program, mssstool64.exe or mssstool32.exe, again.

The initial, full scan by System Sweeper can easily take several hours, but subsequent quick scans will be shorter.
Remember, your computer is being very thoroughly checked for all types of malware.

The results of System Sweeper will be in:
\Windows\Standalone System Sweeper\Support as one or more files with a LOG extension which can be viewed with Notepad.
