Just recently downloaded Kaspersky onto a Windows XP computer, However computer was running very slow with it so I decided to delete the programme. After using CC cleaner it pulled up a range of things including a few DSL files? saying something like disconnected, so I deleted them all and now my Internet Explorer does not have afavoritess bar, I cannot copy and paste, I cannot access the Internet Options in control panel either, when clicking it it pops up slightly then doesn't show. When trying to use Ctrl and F4 that also seems to do nothing. In an internet explorer it usually tells you what web page you are on through the tabs, yet after deleting the files it does not.
Yes I have tried system restore, restarting yet it all seems to do nothing. I even created a new user account, when opening that account it starts up like normal - and attempts to install internet explorer 8 and delete the old one, yet when doing so a loud bang noise happens and we return to the start up mode and the two user accounts again.
What am I supposed to do now? Please Help!
