After Google Chrome and a number of viruses were removed from a Windows 7 64Bit PC, Internet Explorer 32 Bit could not surf the internet, but Internet Explorer 64bit had no problems. This was very odd. I later determined that all 32 bit apps, including Malware Bytes could not connect to the internet.
These are the things I tried to correct the problem:
- Ran a complete scan with Malware Bytes even though the database was 70 days old and cleared off a bunch of junk.
- Uninstalled a few Norton antivurus and malware products, then downloaded and install Microsofts free Security Essentials and completed a full scan
- In IE9 32bit, I clicked the TOOLS cog, INTERNET OPTIONS, ADVANCED, RESET button.
- Using IE9 64bit, I downloaded and installed Firefox 11, but found it could not connect to the internet either
- Checked C:\WINDOWS\SYSTEM32\DRIVERS\ETC Hosts and LMHOSTS files for problems but found none
- Checked network card settings for buggered up DNS settings, but found none
- Deleted both my wired and wireless network cards via DEVICE MANAGER, then rebooted and let them plug and play
- Ran REGISTRY SMOKER to remove any dead links in the registry
- Read dozens of blogs
- Openned a command prompt with RUN AS ADMINISTRATOR and ran netsh winsock reset and rebooted
- Re-registered a pile of IE9 DLLs including regsvr32.exe “c:\program files\internet explorer\ieproxy.dll”
I came close to an in-place upgrade, which is putting in the Win7 CD and telling it to upgrade the current install, but in the end this is what fixed the problem:
- Uninstall Service Pack 1 (SP1) for Windows 7 which shows up in PROGRAMS AND FEATURES, UPDATES, Service Pack for Microsoft Windows (KB 976932)
- Use Windows Update (or IE9 64 bit) to reinstall SP1
- Openned a command prompt with RUN AS ADMINISTRATOR and ran netsh winsock reset and rebooted. You can get more information on this HERE and HERE
There now, wasn’t that easy 🙂
