Hi, since yesterday I am facing the same problem on various Windows 7 machines running Virsucan Plus or Total Protection
After a McAfee update nothing seems to work properly anymore.
Windows 7 reports "no internet access" (an exclamation point on the LAN connection), no WLAN connection and access to the network is no longer possible.
Even during the de-installation the exclamation point on the network icon disappears and after a system reboot everything goes back to normal. (Restart, however, with system freeze)
After a McAfee reinstall everything goes just fine. But after a manual search for new updates, it start installing them and freezes in the process. After this, the error, exactly as described above, occurs again.
What can that be? Is there a faulty update in circulation?
