Windows setting keep resetting!

Hello everyone!

I've a bit of a problem and i have no idea what to try anymore. Someone asked me to look at this PC since Internet Explorer kept crashing on start up so he could not use it. I tried to just reinstall it at first but it gave me and error, and still does (something about the integrety of the nessesary files that can not be checked and to make sure the cryyptography service is running, and it is running when i check it in services.msc). So i went on and installed SpywareDocter 5, there was no spyware removal program on there yet and i heard that one was good. It showed quite a lot of threads and i removed them but off course some came back!

So i went to check online, Internet Explorer did work again now but was REALLY slow. After a while i found that Spyware Docter's gaurd features actually slow it down a lot, so i decided to just get rid of the whole thing all together and just come over here for help and followed the guide.

Now the big problem begins, i had to install Firefox via CD (also installed spyware docter via CD) since although IE now ran, it couldn't download. It keeps timing out. Well no wonder since the security settings are set to not allow downloads, when i change that it just resets it back! This is the same with every setting in IE and also in Windows itself, like for simple appearance settings. I change something and hit OK and it just ignores it and puts it back to what it was. Even when trying to change these settings with a program such as Tuneup Utilities, speaking of which thos settings don't apear to save neither.

Anyway i followed the guide and now there don't appear to be any more threads but i still can't change any settings in Windows whichs is really annoying! If someone can help that would be very much appriciated since i have no more ideas... I've included some logs, but i can't seem to find ComboFix.txt.

Thanks in advance!!!

 

Hello and thanks a lot for the welcome and the quick reply.

Strange i though i uploaded the atachments, let me dot it again for now. And i can't find ComboFix log file anywhere, does this happen to be a hidden file? Since i can't view those since i can't change that option neither, keeps resetting too!

Anyway here are the other two while i look at that readme, thank you so far!

 

Sorry for double posting but when i just went into safe mode to run ccleaner ComboFix ran it's last bit and generated a log file, it didn't do so in normal mode apperently! So here is also the log file of that one, while i still go through the readme for now. The next step i can't do by the way since i can't change any Windows settings, boy this is annoying!

 

Here are the newest logs after i went through the read me's again. The problem still remains.

Sorry another post in here, is there an edit butten? I don't see it, sorry!

EDIT: Oh now i do see it, does it go away after a certain amount of time or something?

 

Hello again!

Thank you so much for helping me so far. However unfrtunatly the problem keeps persisting. I've included the logs that you asked for. Note that i again had to run ComboFix twice since the first time it wouldn't make a log file again, the second time i loaded safe mode and then it did (in safe mode however i can't change any settings neither it seems). So here are the new logs.

 

Hello again,

Here is the newest log and i'll try to explain the problem in more detail now, sorry for not doing so in my previous post.

The problem is that i can't cange Windows settings. It is like they are all locked down in the registry or something. For example, i can't change the view options of folders to show known extensions or hidden files. Once i hit OK in the options window it resets back to what it was. The same is happening for appearance settings, like the start menu does not show the 'internet' and 'e-mail' buttens and the top 6 most used programs under there, it's just white. They are disabled in the propperties for the start menu but enabling them and hitting ok (or aply ok) just resets it back and disables them again. And in Internet Explorer the settins are locked too, most annoyingly there are the security settings which are set so high that you can't do anything with it!

The boot up problem was not that it didn't boot up. The PC works great, but the program ComboFix makes a log file after it's restarted, well here it only would do that if it got rebooted into safe mode, in normal mode nothing happened as if it just was never started in the first place.

I hop this explanation is a bit clear.

Thanks a milion for helping with cleaning, at least there can't be any more damage now. Just wish i knew what the problem was now and how to fix it, i never experienced something like this (well not this severe)!

 

Hello!

I'm very sorry for the late reply. I've been away for a few days so i haven't read your reply yet. However the problem kept persisting and it even occurst in safe mode under the administrator account and it makes it impossible to create a new account this way (well via the normal easy windows way anyway).

The PC had problems for a while so i figure all the infections have damaged it in some way over time like corruption of the registry as you said. I've also noticed that a few files on the hard disc are corrupt to which makes many installed programs unusable. I just decided to format the thing, seemed like the easiest solution to fix everythingin 1 go.

Thank you very much for your great help in removing the (many) mailware infections! It's been a nice learning experience for me!
