Dllhost and tons of Memory Usage

[Chantel4eel]

Hi,

 

I am having some very strange issues with my computer. I am not that computer savvy so I hope I didn't make matters worse. I have noticed that after windows updates, my computer would freeze and run slower but after a few days would work again. However its been freezing a lot lately and some of my programs either won't run or they wont respond but until a few days okay it was tolerable. At first I figured it needed cleaning so I defragmented it and used Malwarebytes and AVG which they found only a couple issues. I did a disk clean but it found nothing major only temp files and what was in the bin. I even tried Slimcleaner.  After that though the computer went even slower so I uninstalled some programs that I wasn't using or were freezing and reinstalled the ones that I do use. Still my computer still reported me using up to 99% of memory but then I noticed it would go way down when not connected to the internet. I found this forum on and also looked at the task manager and noticed multiple dllhost.exe *32  com  surrogate and followed the directions for Malwarebytes settings and it's still not reading anything wrong neither is AVG but now almost every second malware pops up stating Malicious Website Blocked. A few days ago I also started getting webpage error windows constantly popping up and now also a box stating that powershell has stopped working keeps popping up. Now it is running extremely slow even to open simple word documents.

 

Thanks for any help

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll be working with you.
 
     
    
Before we start please read and note the following:

• Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
• Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
• Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
• Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
• Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
• Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
• Note that we may live in totally different time zones, what may cause some delays between answers.
• Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
• If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

I can't foresee everything, so if anything unexpected happens, please stop and inform me!
There are no silly questions. Never be afraid to ask if in doubt!

Hi TwinHeadedEagle,

 

I'm using AVG 2015 but it's not listed under the AVG temp disable list. By any chance is it the same process as one of the older versions listed?

 

Also I noticed when I turned on the computer this time the malware changed its routine. I tried using Firefox instead of Internet Explorer and it my memory jumped to over 90% and task manager said that the bulk came from Firefox but no dllhost *32 showed up and no malware website blocked popups. Then I closed it and tried IE I came straight to this site and popups are none stop both webpage error and the malicious website blocked (outbound). But instead of just the SysWoW64\dllhost.exe it is also using svchost in place of dllhost and malwarebytes is also blocking it.

 

Also besides AVG is there any other program I need to temp. disable that I have on here?

 

Thanks

So I disabled AVG and the firewall and it still kept saying that my security settings wont allow it to download. To make matters worst it wont let me connect to the internet anymore after I tried to download the software. So now I have to log on to another computer using the same network connection.  It loads the browser and malwarebytes has stopped popping up with the website blocker window. Also I know this may sound stupid but was I suppose to disable malwarebyes too (I didn't since it was the only thing blocking it from sending out info.) I have since re-activated AVG and the firewall. I won't touch it until I here back from you.

 

Thanks

Multiple Resident Protection warning!
 
Always have one (and no more than one!) AntiVirus program! In this case having more of them will not provide you with better protection - instead they may cause slowness, lock-ups and even mark another ones as harmful, leading to leave your system unstable and even damaged. Please choose only one from the listed below to stay with and uninstall the others:

• AVG
• Norton Internet Security

Uninstallation procedure:

• Press the + R on your keyboard at the same time. Type appwiz.cpl and click OK.
• Search for each uninstalled entry, right-click it and select Uninstall.

This should be done until any other steps will be taken.

I have removed Norton Internet Security and have been allowed back online. There is also an application called Norton Online Backup do I need to remove that as well?

[Chantel4eel]

Followed the above instructions. Ran the program walked away came back the computer restarted and a box Administrator:ComboFix -Find 3M stating its preparing a log report has been up for about 1.5 hrs now is it suppose to be there that long? (haven't touched it since it started to run as per instructions)

[TwinHeadedEagle]

Yes, you can remove Online Backup too. Restart your PC if report isn't created.

[Chantel4eel]

Restarted computer. How do I get it to create the log report or do I have to redo the process again? Also my AVG also became enabled after startup but everything else is still disabled.

I re-ran Farbar and got the two reports but it wont allow me online to post them on that computer.

[Chantel4eel]

I have attached the two logs. I can no longer use I.E. as it won't allow me to get online but it allows me to get online using Firefox.
