Advanced Startup, Only Enter-Key Works

Recommended Posts



mouse and keyboard of my Windows 8.1 Computer temporarily freeze. When I started considering that a virus might be involved and wanted to boot into a Linux-DVD for scanning, I noticed that in Advanced Startup only the Enter-Key works (which only results in a normal Windows boot). I can't select any of the other options (for example secure boot, boot from DVD etc) as the F-Keys and the digit keys are ignored. All keys of the keyboard work well after Windows has booted. USB legacy support, which is reported to sometimes resolve keyboard problems in the Advanced Startup menu,  is enabled in the BIOS. But I find it rather unlikely that only one specific key works due to a normal SW problem. Windows Defender never reported anything.


Then I tried the following:

  1. ESET online scanner (log file attached) which found some PUP. I asked it to resolve the problem. But this neither changed  the behaviour of mouse and keyboard nor the Advanced Starup menu.
  2. MBAM (log file attached), which I believe didn't find anything serious either. I didn't ask MBAM to delete anything.
  3. FRST from the system recovery environment command prompt. I also attach this log file which contains some ATTENTION-lines which I don't fully understand.


I'm now more or less lost. I believe this can only be a virus, but don't know how to proceed. I'd be really grateful for your help.

They call me TwinHeadedEagle around here, and I'll be working with you.
Before we start please read and note the following:
icon_arrow.gif Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
icon_arrow.gif Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
icon_arrow.gif Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
icon_arrow.gif Do not paste the logs in your posts, attachments make my work easier. There is a Attach Files option below which you can use to attach your reports. Always attach reports from all tools.
icon_arrow.gif Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
icon_arrow.gif Note that we may live in totally different time zones, what may cause some delays between answers.
icon_arrow.gif Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.

Go and remove following:
- Video Download Converter version
- VideoDownloadConverter Toolbar
FRST.gif Fix with Farbar Recovery Scan Tool

icon_exclaim.gif This fix was created for this user for use on that particular machine. icon_exclaim.gif
icon_exclaim.gif Running it on another one may cause damage and render the system unstable. icon_exclaim.gif

Download attached fixlist.txt file and save it to the Desktop:
Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on FRST.gif icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.

Thanks a lot for your help, TwinHeadedEagle! The mouse/keyboard-problem was really annoying. I really appreciated your help!


Actually I found this forum trying to figure out why the Window 8 Advanced Startup menu only allows me to do normal boot and ignores all other options. I found this rather suspicous. It also seemed that other people with  a virus infection of their computers had similiar problems. Is such a  problem in your experience not virus related?

I do not think that some virus will do something so unimportant. I didn't see evidence of some serious virus on your PC that could have done this. You were infected with simple Adware infection.

Thanks again for your help on Saturday afternoon and evening.


I thought compromising the Windows Advanced Startup would keep a user from booting anything else than the infected Windows. But that was just a layman's idea to explain the strange behavior.


Some beer support is on the way ;-)
