Hard to say what is going on the ads, but the HD issue can be assessed from My Computer manager- disk drive management, look to see how your disks are partitioned, formatted and recognized. Sounds like they are not mounting properly in the OS.

It looks like you are missing drives, so right click on my computer Icon, choose properties, then device manager.

The missing drivers should show a ? on it, you can then right click on the missing driver and choose update driver, this should install all missing drivers.

With Firefox, try unistaling it and downloading again.

Also when downloading a new anti-virus make sure there is nothing left of the old 1 as this creates comflict between the programs.
Format your computer.
