On my work (wired) lan, I am regularly, but not always, unable to access any SSL/TLS site. I've also seen recently BSODs with various drivers named as the culprit. Ran full Webroot scan, nothing. Ran Malwarebytes, eventually 'stuck' but after scanning files, where it found nothing (but set off Webroot a couple of times.) Ran GMER and got rootkit warning. This line was in my GMER output:

Library         pö¶ö¶ é||ö¶ (*** hidden *** ) @ C:\WINDOWS\Explorer.EXE [5588]                                                                          0x07EA0000             


This vaguely resembles TDSS but not sure. Suggestions? I have the full log from GMER and from a 3rd party scan (I'll wait for that to be requested, almost 1000 lines long.)

Know I'm not supposed to but kept working on this: 1) Tried TDSSkiller, nothing found. 2) I had a coulpe of incidences where my graphics driver died, so figured I would update. Downloaded the latest ( from Lenovo (also on Intel's site) and tried to install. I get a strange message that "You must have administrator rights to complete this action. Setup will exit. <OK>". The driver never installs and reboot show the old driver (*.5043) still there. Even when I run in safe mode with full local machine administrator rights. Attempting this a coulpe of times has earned me a BSOD too.

Edited to add-mbam hangs on "checking other items"after file scan. Left it overnight. mbar gives me dda driver warning. would report myself for log posting (didn't realize that applied to more than the listed logs) for transfer to the other forum but can't on mobile view...

OK, I'm going to post in the other forum for Logs. Explorer on my computer regularly runs at 20-30% of CPU now. Clearly something going on. I'll post the cross link.

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 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 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 MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 2 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook
