Registry Error Created

Hello,

I recently ran the Registry Cleaner on CC Cleaner as I do on regular basis to keep my computer clean of files I don't need. Unfortunately this most recent time has created some type of error. I ran the cleaner and it brought up one type of registry error, I did not create a back up because it stated it was related to some type of uninstallation, which I had done several of recently. Afterwards I went to get on Internet Explorer and it could not find any webpages, bringing up the web page stating that website could not be connected to. I then tried aol which also displayed an error and could not even get pass locating the AOL VIA/TIP connection. AOL then pops up with a little box stating ERROR ee://connectivity/connectivity ERROR 72

What did I delete?

How can I fix my interent?

Please HELP!! :(

Also I have tried using a previous restore point but the problem still persists. I am on another computer right now......

What software are you using for firewall and Antivirus/MalWare?

it could be a reg entry for one of them (this'll teach you to not make a backup ;) )

i use Mcafee but it seems to be working correctly except for prior to this error the computer protection would keep turning itself off and I would have to turn it back on constantly; this happened all of the sudden which is part of the reason I ran the registry cleaner

after talking with comcast who m high speed is through they said that my modem was not connecting....should I reintsall the modem software? or has this deletion done something else? they recommended I get a new modem from them, but I don't think this is necessary as it has to be this registry deletion because I remember connectivity or connection being in the file name

Well somehow I've fixed the problem by route powering the modem.....evidentally the deletion was not the source, anyways lesson learned as far as backup files :P Thanks!!
