Hi,

I have a WinXP machine T500 Lenovo laptop, that which started behaving strangely. A virus scan (Avast) found some infected files and root-kit and quarantined a bunch (8) of .sys files:
afd.sys, CDROM.sys, rebook.sys, serial.sys, IPSec.sys, netbt.sys, i8042prt.sys and mrxsmb.sys.

Once rebooted, there is no keyboard and track point since i8042prt.sys is gone, there is no CDROM (CDROM.sys), and no Internet connection (IPSec.sys).
I tried restoring the missing files with the following methods (as suggested in various posts here and elsewhere): copy from another machine, use regsvr32 to register them (fails), expand from xp cd install dir, use sfc. None of these methods made any difference.

I ran various additional cleanup tools including ComboFix and TDDSKiller, but to no avail.


Additionaly the the access connections service AcSvc.exe and it's child SvcGuiHlpr.exe processes immediately begin consuming 50% CPU each choking my pc. I can only resume work by suspending them using Process Explorer.

Please advise,
Thanks,
Adi

Since you ran combofix, Please follow the instructions in ==>Malware Removal and Log Section Preparation 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. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

Once you have created the new topic, please reply back here with a link to the new topic.

Most importantly please be patient till you get a reply to your topic. If you receive a reply from the HelpBot, then please follow the instructions outlined in the helpbot's post.

Hi,

Thanks. I just found this forum so I am not familiar with the rules and did not see the Preparation Guide.
Will do it asap.
Thanks,
Adi

Now that your log is properly posted, 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 Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the logs 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 Malware Removal 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 Malware Removal Team members are very 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 Malware Removal 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 Malware Removal Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
