dllhost.exe*32 and other processes slowing down computer

[Patrick23]

1. dllhost.exe*32,iexplore.exe*32, saUI.exe*32, rundll32.exe and other processes are running multiple versions of themselves using up CPU and Physical Memory.

 

2. Internet sites are showing up in the Applications tab of Windows Task Manager which I did not open. The sites and Internet Explorer don't show up on my desktop but the sites are running because I can hear ads and audio from the sites through my speakers. "End Task" won't close them.

 

3. I tried to download Farbar Recovery Scan Tool from bleedingcomputer.com to get a scan for you but I get a popup that says "Your current security settings do not allow this to be downloaded."

 

I've never had issues downloading things before. Malwarebytes quarantined a couple of files today but this didn't help any of the issues.

 

Any help would be appreciated. Thanks.

[Patrick23]

I was able to get Farbar downloaded. The scan files are attached.

BACKDOOR WARNING

------------------------------

One or more of the identified infections is known to use a backdoor, that allows attackers to remotely control your computer, download/execute files and steal critical system, financial and personal information.

Please disconnect your computer from the internet immediately. If your computer was used for online banking, has credit card information or other sensitive data, using a non-infected computer/device you should immediately change all account information (including those used for banking, email, eBay, paypal, online forums, etc). Consider these accounts already compromised.

If you have used a router, you will need to reset it with a strong logon/password to ensure the malware cannot gain control before connecting again. Banking and credit card institutions should be notified of the possible security breach immediately. Please read the following for more information: How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Whilst the identified infection(s) can be removed, there is no way to guarantee that your computer will be trustworthy again. This is due to the nature of the infection, which allows the attacker complete control over the computer. Many experts in the security community believe that once infected with this type of malware, the best course of action is to reformat the hard drive and reinstall the Operating System. Please read the following articles for more information.

• When should I re-format? How should I reinstall?
• Help: I Got Hacked. Now What Do I Do?
• Where to draw the line? When to recommend a format and reinstall?

Please let me know how you wish to proceed, and if you have any questions.

[Patrick23]

I will attempt a re-format. I recently(two weeks ago) had the computer brought into a "Professional". I had backed up all my documents and family photos at that time so I'm not losing anything by re-formatting. They told me they found 1 virus and the system was clean but I've had worse problems ever since.

[LiquidTension]

Unfortunately, that isn't the case. The machine is infected with Poweliks, and remnants of ZeroAccess. Both infections open a backdoor on the compromised machine.

ATTENTION: ====> ZeroAccess. Use DeleteJunctionsIndirectory: C:\Program Files\Windows Defender

 

Do you require additional assistance now that you have decided to reformat?

[Patrick23]

No I won't require more assistance. Thank you for helping me and identifying what I was up against!

[LiquidTension]

OK.

 

Good luck with the reformat. I shall close this topic.
