Problems - Nothing In Taskbar / Freezing / Can't Copy or Paste, Need Help With Variou

[andantesash]

Hey - I hope someone can help.

I turned my computer on today after using it last night, it was fine.

So I turned it on this morning and here is what is happening:

1) No programs or files are appearing in the taskbar when I open anything, its just blank

2) I try to copy and paste files or drag them, but they don't work

3) Can't get on the internet explorer, a box like (cmd) pops up for a milisecond and disappears, nothing happens.

4) I tried uninstalling the internet explorer, but the option isn't there to uninstall or reinstall?

5) I tried uninstalling other programs, it says a problem with Windows Installer.

6) So I try to re-install windows installer and it cant because there is a problem with cryptographic service, so I went to services to enable it and it says 'Error 1068: the dependency service or group failed to start"

7) I have ran Avast on it, both as a normal scan and boot scan, also ran CCleaner and cleaned everything up and deleted found viruses, also ran Ad-Aware and quarantined 2 or 3 files.

The same problems are happening, can anyone help me?

You may want to try and run System Restore. If you don't know how I can give you a shortcut.

I would restore your system to about one month earlier if possible. Then after using System Restore I would run the virus scan again to make sure there is no malicious software on your hard drive.
