Hi there,
My PC became infected with Windows System defender a few days ago.
I have managed to delete most of it from the system following some advice found on other website however, Windows System Defender has somehow managed to disable “Search” on my PC and also “Command Prompt”. I can no longer access MS DOS.
Whatsmore, my PC cannot run System Restore any longer either.
When I click on System Restore, my PC says it cannot read “.DAT” files.
Can anyone offer me any help or advice?
Thank you very much
Joe
