Some web sites do not open

If you have a problem opening some web pages these tips may help you. They are about to heal symptoms, not the cause. The cause is usually virus activity.

  1. Open this branch of a registry: cmd-> regedit -> [HKey_Local_Machine\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\PersistentRoutes]
    It must be clean, except default entry.
  2. Try this in Start/run: md /k notepad c:\WINDOWS\system32\drivers\etc\hosts
    It must be clean, except localhost entry.
  3. Find faults in the pipeline: cmd /k tracert
    This tip doesn’t help to fix, but to diagnose.
  4. Clear dns cache:
    cmd /k ipconfig /displaydns
    cmd /k ipconfig /flushdns
  5. Install and run antivirus, for example, Kaspersky antivirus, trial version.
