Hallo to everyone,sirry for my bad english, but i'm an italian user.
i'have my laptop (packard bell whit vista 32 bit) that is under attack...
rootkit,virus, varieus problem, crash and blue screen

i can only open the safe mode.
if I start Windows when I try to log into my account, the PC crashes and a screen Blue
I therefore start in Safe Mode.
I have used many programs that have removed virus (also in the linux version) but I have not resolved.
When I reboot in safe mode again reappear :wacko: :wacko: :wacko:

GMER found this Rootkit
C:\Windows\System32\drivers\pxkbf.sys (*** hidden *** ) [DISABLED] pxkbf <-- ROOTKIT !!!
Service C:\Windows\System32\drivers\pxrts.sys (*** hidden *** ) [DISABLED] pxrts <-- ROOTKIT !!!
Service C:\Windows\System32\drivers\pxscan.sys (*** hidden *** ) [DISABLED] pxscan <-- ROOTKIT !!!
Service System32\drivers\pxsec.sys (*** hidden *** ) [DISABLED] pxsec

These files belong to the Prevx programm, but i think that prevx is infected beacuse , If I open Prevx, an alert tells me that is not licensed Cleanup :blink: ..and the scanning end.

Then i found in C: a file CLEANUP.exe that is a trojan(result of virustotal)

This is the log of MB Rootkit detector...

Please follow the instructions in ==>This Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include the link to this topic in your new topic and a description of your computer issues and what you have done to resolve them.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic397921.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.
