I did what you suggested and there is still no sign of my laptop getting out of its lockdown.
The programs that can't connect to the internet are installations that require internet access, OpenOffice, uTorrent, Steam and Winamp. There are possibly more programs that can't connect to the web but I haven't used them :)

If you still can not get anything else to connect to the network, try the following:
Download and install Windows Repair from here.
Uninstall ALL anti-malware / anti-virus programs and any system monitoring software BEFORE running this program (I think I remembered you have Advanced System Care (?) on your system). Dis-connect from the Internet as a pre-caution (since no AVs) and do not re-connect until after the repairs are complete.
Run the Windows Repair program and do Steps 2, 3 and 4. (Step 1 is for infected systems and would require use of other tools.) Make sure to run the System Restore and Registry Backup (both tasks) in Step 4. The System File check and / or Check Disk may ask to reboot your system to run properly so follow the prompts.
Under Start Repairs (step after Step 4), click Start and then click on Unselect All. Next click on (check) the following repairs:
Reset Registry Permissions
Reset File Permissions
Register System Files
Repair Windows Firewall
Repair Internet Explorer
Repair Hosts File
Repair Policies Set By Infections
Repair Winsock && DNS Cache
Repair Proxy Settings
Repair Volume Shadow Copy Service (you may omit this one IF the System Restore backup functioned OK)
Set Windows Services To Default Startup
Make sure the Restart / Shutdown System When Finished is NOT selected and then click START. DO NOT start / run any thing else on your system while this is running; several / many CMD windows will open in the background while Windows Repair runs commands to reset / repair your OS. Windows Repair will notify you when it is done; if any of the CMD background windows are still running, allow them to finish before you restart your system.
Once the system is restarted, connect to the internet and check if the previously blocked programs can access the network. Then install and activate your choice of AV software.
