AVG AntiRootkit finds the following :
" C:\WINDOWS\System32\Drivers\amsddwdi.SYS,Hidden driver file "
Every time I remove it,(AVG AntiRootkit,then reboot),it reappears,except the letters change,(amsddwdi will be something different.)
(I replaced AVG 8 with Avast as Avast apparently terminates rootkits on startup,but this Hidden driver file still appears.)
My PC seems to be running fine,except :
1 - Firefox seems sluggish,though IE8 and Chrome seem fine.
2 - CPU usage is about 5 - 15 % while just browsing,seems rather high?
3 - Uh,that's it !
There is no unusual received/sent networking activity on Task Manager.
Is the Hidden driver file malicious and should it be removed?
I plan to use combofix and malwarebytes unless advised otherwise.
Thanks in advance for any advice!!
