My pc was infected by an unknown malware, it is my first time to encounter a malware like this. All my files on my hard drive was changed the attribute to hidden except for the desktop shortcuts and then it replaced the files with the same name as it is and then the replaced files has an .exe file extension. I already tried to scan the system but my anti virus didn't detected something, I also tried to locate the virus in cmd but I can't find anything and I also tried to remove the hidden property of my files and deleted the fake one but it is useless the malware always changing my file attributes to hidden and replaces them with fake ones w/ an extension of .exe . My last solution is to reformat but i do not want to lose my files. I need help........

Go to Start | Run and type in msconfig and hit OK. Select the Launch System Restore button.
The radio button for Restore my computer to an earlier time should be selected then go next.
Select a date previous to when you got infected and select next.

Hopefully that will sort it.

I forgot to mention i already tried to go on restore point still just the same.
