I'm worried about the 25 min delay with Control Panel AND THE FACT THAT YOU CAN'T OPEN ANTIVIRUS SOFTWARE. Gives the picture that your computer is blocked.
I would suggest, plug all Internet connections off, run a thorough Antivirus and Malware scan to find out about problems. If you even suspect your Security Programs are outdated, there are several options to get one on a USB stick, found on the net, like Link Removed If this is the option, get it downloaded to a clean stick by a friend - not your computer.
Preferrably all in Safe Mode. And, these aren't foolproof, though.
The delay in connecting to Internet isn't that bad, it may be a problem with the router or server. You could give some system specs?
