Somebody who shares the dropbox I have for working told me there is a rootkit in the dropbox. I do not know how to check that, or maybe it is his computer ? I am checking my computer but I cannot find anything. I tried running GMER but it keeps crushing. Maybe I should worry? GMER started finding that the definition updater from Windows Defender may have a rootkit, but it just crashes after that. I am running Windows 8.1, but there is also some more computers in the network and a Windows 2008 NTserver at work. I found all kind of information, I just found that rootkits are almost impossible to find. What should I do? Do you have any suggestion?
I run hijack this and have the boot log on, but I cannot identify anything strange. Thank you for your help.
