Hi, I had malware, spyware, virus what you would like to call it. I downloaed the free version portable SAS and ran the full scan. And removed the virus. So I thought. It asked me reboot and once I did now it comes to a black screen with mouse pointer. Anyone know how can I undo the repair or fix it. I think it removed the system critical files. I want to know what exact files it removed so I can somehow extract the files from the cd. I have tried the repair my computer option, I cannot reinstall windows 7 as it needs windows to reinstall. Please help! I have Win7 64 bit.
