Hello all, creating this topic in the hopes of quelling some paranoia or to eradicate some malware.  Either outcome is alright by me. 

 

Some time ago I needed a file patch and (probably) clicked one of the dozen or so fake "download" buttons on the webpage.  Went ahead and downloaded the file even after it told me there would be other files bundled in.  Immediately after the download my internet security blew a gasket, quarantined a bunch of files as a live response, and I thought that was the end of it.  Then I started getting a bunch of ads appearing out of nowhere on my browser screen.  New tabs would just open and there'd be an ad.  Ran MBAM, discovered a bunch of extra stuff my security software missed, and deleted.  A week later, my credit cards were being used in different states around the country.   :ranting:

 

So, after handling all the fraud mess, I ran a system restore on my PC and hoped for a clean slate.  I didn't choose the "Save personal files" option, I went with the "Nuke everything to oblivion" option.   Now my PC is getting weird again.  When I turned it some days ago, my internet was disconnected and all my anti-malware programs were disabled.  Fixed those without issue, but now every time I log in my anti-malware programs are disabled and I have to enable them manually.  When I look under my security and maintenance tab in the control panel, it says everything is still turned off despite my programs appearing to be working as normal.   And the ads are back, but nowhere near as frequent as before.  

 

Downloaded rkill, nothing but there were about a dozen or so notes under the Miscellaneous tab in the report file. 

Downloaded MBAM again, search came up with nothing. 

Downloaded MB Anti-Rootkit, nothing.

Downloaded AdwCleaner, nothing. 

 

https://www.bleepingcomputer.com/startups/dllhst3g.exe-26573.html

https://www.bleepingcomputer.com/startups/dllhost.exe-16363.html

 

Like before my system restore, these programs like to be active in my background processes.  If I open my task manager they will disappear within seconds.  If I close it, they'll come back until I open it again.  They both trace back to my system32 folder.

 

 

I'm running Win10.  I'm hoping it's just some bugs in windows 10, I need some expert advice on this because I'd rather be safe than sorry.  FRST logs are attached below.

Yes, I still need help. 

Don't understand the question about the CD/DVD

Here are new logs. 

 

Also possibly related to the popup ads, I keep getting certificate errors notifications from my AV about an extension cdn.taboolasyndication.com.  I'm not on that website at all and it doesn't look familiar.

Sorry for the late reply, I wanted to give it a day to see if anything would pop up.  No intrusive ads since the fix, I've also noticed that my computer doesn't tell me that my security software has been disabled anymore   :thumbup2:

Perusing your logs, I see no infection currently present in your system. Unless you are having any issue(s), the machine appears to be Malware-free as we speak.

 

♣ Removal of Tools and Quarantined Files ♣


 

Despite the tools we have used are clean, they are powerful removal tools and made in a way so that they carry out any commands given to them without (most cases) asking for a confirmation. In the hands of an inept person, they can make the machine un-bootable -- a scenario we do not wish to see. Also, we need to remove the quarantined files/folders from your system as a dormant malware can be as bad as an active one if given the proper environment. I shall now give you the guidelines to remove the tools and the quarantined files from your system.
  • Cleanup with Delfix
    Please download DelFix by Xplode to your Desktop.
    Download Link
    • Double-click to run the program;
      • Note: Windows Vista/7/8/8.1/10 users right-click and choose Run as administrator
    • Make sure that all the boxes are checked;
    • Click Run;
    • A log will be opened after the operation is finished;
    • Copy and Paste it in your next reply
 

♣ Prevention and Future Guidelines ♣


 

Prevention is better than cure -- goes the old saying. As much as we love to see you visit our site, we do not want to see you having your PC infected by malwares again.
  • Keep Windows up-to-date.
    It is extremely important that you keep your operating system (Windows) updated when updates are made available. It is set to alert you, so be sure not to ignore these notices and to allow the updates to install. Many of these are critical security packages which could very possibly be the difference between your picking up a future infiltration and simply passing right by it unharmed.
  • Run antivirus software and keep it up-to-date, too.
    Antivirus software is your safety net if all other protections fail. The first line of defense is smart computing, of course, but everyone needs a backup. I'd recommend Microsoft Security Essentials or avast!, both of which are excellent, as well as free. Once they're installed, check periodically to ensure they have been successfully updating as well. An out-of-date antivirus is not a happy antivirus!
  • Keep your web browser plugins and other programs updated also.
    This tip is rarely shared by technicians and its importance is not widely recognized, but it's absolutely critical. Programs such as Java, Adobe Flash Player and Adobe Reader, Internet Explorer, and myriad other such web-exposed items are deeply vulnerable to attack, which can quickly lead to a hopelessly infected system no matter what protection you currently have installed. The reason is that these programs are ubiquitous, but are also not perfect and are extremely complex... and as such, security vulnerabilities are discovered and exploited by hackers hoping to gain control over your machine. By performing every update for these programs as soon as it's made available, you will greatly reduce your exposure to dangerous internet threats.

    A great way to do this is to install the Filehippo Update Checker and run it regularly. Also, try not to ignore any notifications you receive regarding updates to programs already installed on your PC.

    No scripts is an excellent security device too. I like it but it is not for everyone because it requires you to take action if you want to see some things (pop ups, banners etc.) on sites you visit.

    Download NoSript by Giorgio Maone.

    Note: Sometimes you will get a site telling you that you need to install Java when actually all you need to do is enable the site through the no script icon down on the right hand side of your computer.
  • And last of all, surf smart.
    It doesn't matter how well the autopilot system works if the pilot keeps flying the plane into mountain ranges. Don't forget that no matter how much you have protecting yourself, your security ultimately begins and ends with you. Don't visit dangerous or questionable web sites, avoid suspicious links on Facebook and emails/email attachments you're unsure about, and just generally keep your wits about you, and you'll be much safer. Also, avoid illegal downloads, cracks, "warez", and all other too-good-to-be-true internet offerings: they're typically laden with malware. Be smart and you can avoid most threats lurking about the darker corners of the internet! And for even more tips, see our article How Did I Get Infected in the First Place? and Keep Your Computer Safe Online.

Valinorum
