Hi,
Here are all the logs.
Also there used to be an svchost.exe issue too as a few other posts have asked for, but it kind of went away on its own before i could do anything about it. Could you check that out too?
Thanks

Hello,


Please note that these fixes are not instantaneous. Most infections require more than one round to properly eradicate.

Please stay with me until given the 'all clear' even if symptoms seemingly abate.

Kindly follow my instructions and please do no fixing on your own or running of scanners unless requested by a helper



---     ---     ---     ---     ---


First, you need to uninstall Google Chrome browser. It has been compromised by malware as it is changed in developer version. All security features in Chrome are now disabled by default. This need to be fixed first. Make shure to chech the box 'Also delete your browsing data' as we need to remove preferences as well.

So, uninstall Google Chrome web browser and then continue and preform fixing with FRST tool.



---     ---     ---     ---     ---



This FixList shall target the malware. When FRST finnish with fixing, it will ask and preform the system reboot.


1. Open notepad and copy/paste the text present inside the code box below.
To do this highlight the contents of the box and right click on it. Paste this into the open notepad.

2. Save notepad as fixlist.txt to your Desktop.
NOTE: => It's important that both files, FRST and fixlist.txt are in the same location or the fix will not work.


3. Run FRST/FRST64 and press the Fix button just once and wait.
If the tool needed a restart please make sure you let the system to restart normally and let the tool completes its run after restart.

The tool will make a log on the Desktop (Fixlog.txt). Please attach it to your reply.
Note: If the tool warned you about the outdated version please download and run the updated version.

Now, download fresh Google Chrome installer and install it. Sing in into Gmail account and all your personal data and bookmarks will be synced.

Hi,
 Done as mentioned. Chrome has been installed again. Fixlist.txt kind of disappeared from the desktop after the reboot. Is that normal?
The Fix Log is attached.
Also the svchost.exe issue had come back along with the chrome.exe but that was before applying the FRST fix. Just so you know. :)

Hi,
I have not received any popups the last time I booted ( they came every time I booted or when the PC connected to the internet), so that's good. I could monitor for some more time.

The problem was in Google Chrome web cache and add-ons. You should be good to go ... 
Glad I could help. Since posted logs appear cleans and show no signs of active infection, you may read these tips in my finall speech. 




We're gonna remove my used tools now as well as carry out some further cleaning and security settings. To learn more about how to protect yourself I'll give you a few tips for reading. 



The following will implement some post-cleanup procedures:





---     ---     ---     ---     ---


Please download DelFix by Xplode to your Desktop.

Run the tool and check the following boxes below;
Remove disinfection tools
Create registry backup
Purge System Restore

Click Run button and wait a few seconds for the programme completes his work.
At this point all the tools we used here should be gone. Tool will create an report for you (C:\DelFix.txt)

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.





Tip: Do not use security tools such as ComboFix, FRST, Zoek and the like. These are advanced security tool, should not be used without supervision.



---     ---     ---     ---     ---



Learn how to protect yourself:



=>  In order to stay protected it is very important that you regularly update all of your software and Windows Operating System.

It is important that you visit Windows Update regularly.
How to configure and use Automatic Updates in Windows

It's vital that you keep all your software up-to-date as older versions may have some security vulnerabilities. Keeping Java and Adobe update is priority.
Download and install latest version of Java
Download and install latest version of Adobe Reader




=>  I recommend that you use one of the fantastic opportunities provided by avast! AntiVirus.

For security protection, an active AntiVirus is required. If you want to reinforce your security setup I recommended additional security software and utilities:
Download and install Malwarebytes' Anti-Malware and perform 'Threat Scan' from time to time. Malwarebytes will detect and remove all traces of known malware.
Download and install MCShield Anti-Malware Tool to prevent infections transmitted via removable drives.
Download and install Unchecky to keeps your checkboxes clear by preventing installing additional adware and other PUP bad software.
Download and install AdBlock for safe web browser surfing without annoying and malicious advertising ads.
