Awesome! :) No problem. All the credits goes to my colleagues who just finished investigating this new infection as well, it really helped out!

Since there are no signs of infection anymore in your logs, and you just told me that there are no more issues left to address, I guess we're done here. We'll wrap it up by running DelFix to delete the tools and logs that were used in this clean-up.

BWuhenj.pngDelFix
Follow the instructions below to download and execute DelFix.
  • Download DelFix and move the executable to your Desktop
  • Right-click on DelFix.exe and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Check the following options :
    • Activate UAC
    • Remove disinfection tools
    • Create registry backup
    • Purge system restore
    • Reset system settings
  • Once all the options mentionned above are checked, click on Run
  • After DelFix is done running, a log will open. Please copy/paste the content of the output log in your next reply
Qt25440.pngTips, tricks, advice and recommendations

Now it's time to give you some tips, tricks, advice and recommendations on how to protect your system and prevent you from being infected in the future. This is where I'll explain basic security measures that you should take to protect and harden your system, and also make sure it stays as safe and secure as possible against hackers and malware. You are free to ignore the recommendations listed below, although I obviously do not recommend it. If you have any questions about one of the points covered in the speech below, feel free to ask me your questions here directly so I can answer them and guide you.

Windows Updates

Keeping Windows up to date is one of the first steps in having a safe and secure system. The Security Updates that Windows receives are meant to fix exploits and flaws in it that makes it more secure and not exploitable by hackers. In order to do that, you should always install the Security Updates, known as "Important Updates" on your Windows system. These updates are released on the second Tuesday of every month, but some are also released before if they are emergency/critical Security Updates. Let's make sure that you have all your Important Updates and Recommended Updates installed and that your Windows Updates are set to be installed automatically.Keeping your programs up-to-date

Like keeping Windows updated, keeping your installed programs up-to-date is another important step in having a safe and secure system. Outdated programs can be exploited by hackers and malware to infect a system and take it over. This is especially true today with the rise of Exploit Kits (and also 0-days) which is one of the biggest attack vectors to distribute malware. Therefore, you should always keep vulnerable programs like Adobe Flash Player, Adobe Shockwave Player, Java, Silverlight, Google Chrome, Mozilla Firefox, VLC Media Player, etc. updated to their most recent version (even better, you don't have to install them if you don't use them). Programs like eLDnJfI.pngSecuniaPSI and y5YE7At.pngHeimdal Free will scan your system for outdated programs, and help you identify them, as well as update them.Anti-Virus, Anti-Malware, Firewall and Anti-Exploit/Ransomware

Having a decent security setup (which also includes an Anti-Virus) is the most crucial step to protect a system. These programs are a layer of defence that will prevent a system from being infected, or if it somehow ends up infected, help mitigate the infection and remediate it. Ideally, you should have on your system one Antivirus (never more than one installed at the time), one Antimalware (you can install multiple of these, assuming they do not conflict with each other and the other security programs installed), one Firewall and if you wish, one Anti-Exploit and/or Anti-Ransomware (since Ransomware are currently the most dangerous threat around and it can hit anywhere). Here are a few programs worth checking out if you don't have one yet.

Note: The programs listed below are all free to use or they have some sort of trial. Some of them have a paid version that provides more features, while a lot of other good programs only have a paid version but aren't listed there (such as Kaspersky and ESET Antivirus products).

Anti-VirusAnti-Malware
  • j1Bynr2.pngMalwarebytes - Has both a free and paid version. The Premium version of Malwarebytes also offers Exploit and Ransomware protection, for a complete package of: Malware, Web, Exploit and Ransomware protection
  • S2NFpNw.pngHitmanPro 3 - Free 30 day trial
  • ncqvIpu.pngZemana AntiMalware - Free 30 day trial
Firewall
Starting in Windows Vista, the Windows Firewall greatly improved and will satisfy the needs of most users. If you do not have an Internet Suite Antivirus program (which includes a firewall) and you want to use a 3rd party firewall, you can consider the options below.
  • 7p3JzTS.pngGlassWire - Has both a free and paid version (with different packages)
  • MQIMh6k.pngWindows Firewall Control - Gives you more control over your Windows Firewall
  • 5RXGshU.pngTinyWall - Lightweight firewall implementing the Windows Firewall and giving you more control over it
Anti-Exploit/Anti-RansomwareWeb Browsers and Web Browsing

Web Browsers could be considered as the closest door between a malware and your system. This is where most malware goes through to infect a system, and therefore it should be the program(s) you want to secure the most. There are two ways of going about it: hardening your web browser via extensions, and having good browsing habits.

Hardening your web browser means to install extensions that will help it protect itself (and your system on the same occasion) against Exploit Kits, MiTM attacks, etc. but also you at the same time. Here are a few extensions that I recommend you to install.
  • uBlock Origin: Efficient multi-purpose blocker that is lightweight on RAM and CPU usage (Google Chrome, Mozilla Firefox, Microsoft Edge, Opera and most Chromium and Firefox-based browsers)
  • HTTPS Everywhere: Extension that converts your HTTP (unencrypted) requests to HTTPS (encrypted) ones (Google Chrome, Mozilla Firefox and Opera)
  • Web of Trust: Website reputation, rating and review extension that will help you quickly identify bad and suspicious sites from good ones (every web browsers)
  • NoScript: NoScript is a script blocker (Java, Flash, JavaScript, etc.) for Mozilla Firefox and Firefox-based browsers (Mozilla Firefox and Firefox-based web browsers)
  • uMatrix: For advanced users, a point and click matrix-like extensions that allow you to control requests done on a webpage (based on source, destination and type) (Google Chrome, Mozilla Firefox and Opera)
  • LastPass: Secure password manager allowing you to create, manage, and use passwords you save in your LastPass account (every web browser)
As for safe browsing habits, you can find tons of guides, tutorials, articles, etc. online that will highlight the basics you need to follow (only visit websites you trust, do not click on ads, do not download files from untrusted sources, use a password manager, always verify the URL of a website and make sure it's correctly typed, etc.), and even what you can do if you want to take it a step further (create a fake email address for spam emails, browse the web in a privacy mode, etc.). Here are a few:As you can see, there are plenty of resources out there. Simply Googling "good browsing habits" or "safe browsing habits" should allow you to find a lot of them.

Other recommendations

Even if you follow every recommendation that I listed here, in the end, it's also your job to be careful when browsing the web and downloading files if you don't want to get infected. Therefore, if you use your brain (common sense) when browsing the web, downloading programs and files, etc., you have far less chances to get infected by a malware. If for example you're not sure if a website is legitimate or not, or if a file is safe to download and execute, or if a program looks "too good" to be free, I suggest you to avoid going to that website, downloading that file or using that program.

Here are a few guides, tutorials, articles, etc. that you could read in order to learn more about computer protection and security to improve your current computer protection setup but also improve your good web browsing and computer usage practices :gRvSooB.pngThe End!

And that's it! Now that you know more about how to protect your computer and secure it, you're good to go back to your online activities, but in a safe and secure way! You are also free to stay on the forums and ask for help in different topics if you ever need to. Just make sure that you post your question/issue in the right section to get the best assistance possible. And if you ever get infected again (which I hope you wont!), you can always comeback in this section to get another checkup with one of our trained malware removal member.

Do you have any questions before I close this thread? :)

"Reset System Settings" enables file extensions, disable the ability to see hidden/system files and runs a netsh winsock reset. Nothing harmful there :)

Well i have 2 more problems but i dont want to bother you with them because i dont think they are cause by virus and im having them for long time but i will ask maybe you will know.

 

1st problem:

 

Sometimes (like 20%) when i open task manager it freeze for like 1 second and after shutdown when i open again like 1 or 2 more times it do the same but after it work normally...

 

2nd problem:

 

When Iam booting PC: Press On button>keyboard and mouse light up>POST screen>Windows loading and during this keyboard and mouse turn off>login screen> i have to wait like 20 seconds for keyboard and mouse to light up again so i can type my password <Why? Some drivers problems?

 

Last question: It is normal i have 3 times "COM Surrogate" in task manager and after like 3 seconds after i start task manager they disappear?(i was worried once it is virus but now i think its normal)  >  https://imgur.com/a/LX7jD

 

I know all of those thing are strange and maybe out of your "proffesion" so i dont want to bother you with them...

Freeze how? Does it enter a "is not responding" mode?

When Iam booting PC: Press On button>keyboard and mouse light up>POST screen>Windows loading and during this keyboard and mouse turn off>login screen> i have to wait like 20 seconds for keyboard and mouse to light up again so i can type my password <Why? Some drivers problems?


It could be a driver issue. If I were you, I would start by updating your chipset and USB 3.0 (if you have any) drivers.

Last question: It is normal i have 3 times "COM Surrogate" in task manager and after like 3 seconds after i start task manager they disappear?(i was worried once it is virus but now i think its normal) > https://imgur.com/a/LX7jD


Looks like it is, because I managed to reproduce it on my system normally by opening the Task Manager :)

Might be related to the various crashes of fontdrvhost.exe that I see in your Event Viewer, but this looks more like a Windows issue than a malware-related one. So you could ask about it in the Windows 10 Support section :)
