Hello, Welcome to BleepingComputer.
I'm nasdaq and will be helping you.If you can please print this topic
it will make it easier for you to follow the instructions and complete all of the necessary steps.
Your infection may have cause this start menu issues. Try this.
To make your files visible again, please download the following program to your desktop:Unhide.exe
Once the program has been downloaded, double-click on the Unhide.exe icon on your desktop and allow the program to run. This program will remove the +H, or hidden, attribute from all the files on your hard drives. If there are any files that were purposely hidden by you, you will need to hide them again after this tool is run.
This may take sometime, please let if finish.
However, the newer variants of the FakeHDD rogue programs are now deleting the following folders and storing them into a numbered folder under %Temp%\smtmp\
%Temp%\smtmp\1\ => %AllUsersProfile%\Start Menu
%Temp%\smtmp\2\ => %UserProfile%\Application Data\Microsoft\Internet Explorer\Quick Launch
%Temp%\smtmp\3\ => %AppData%\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
%Temp%\smtmp\4\ => %AllUsersProfile%\DesktopIt goes without saying that running a %temp% cleaner ahead of restoration would result in loss of these folders
<- you may have already run such a tool.
Keep me posted.
