False alarm?

[REDACTED]

Hello guys,

I am new here, I hope I am posting in the correct place.
Since yesterday, everytime I use Google Chrome to browse the internet, I get many alarms, which I am not sure whether they are false alarms or not. I have attached 2 images, showing the alarm I get.
Any help would be gladly appreciated.

Regards, Kyriakos

I have attached the logs

Could you confirm that it is in chrome only .. If so then try Chrome in incognito mode, does that stop the alerts

Hello again,

This alarm only happens in google chrome. I have tried using Chrome in incognito mode and it stops the alerts.
What solution would you suggest?

Many thanks!

OK lets now cure that

Re-install Chrome

1. If you have bookmarks, let's save them by exporting them - Export Bookmarks
2.Go into the dashboard. Log in. https://www.google.com/settings/dashboard?hl=en
3.Scroll down to “Chrome Sync” and click “Manage Chrome Sync” on the right.
4.Go to bottom of resulting summary page and click “Stop and Clear.” It will ask you if you really want to, and if you do, in fact, really want to, click “Ok.”
5. Now we need to uninstall chrome.
 Note: When asked about user data or settings you must remove this also so please check the box.
6. Restart the computer and reinstall chrome, You can download The latest version from here - Google Chrome
7. Import your bookmarks back into Chrome
8. Sign back in to your Chrome browser so that your bookmarks sync with your online account.

Looks like this was the culprit

CHR Extension: (Facebook Video Downloader) - C:\Users\Kurk\AppData\Local\Google\Chrome\User Data\Default\Extensions\amjcoehkcacocffpmhnefgoeanepjfkf [2016-04-27]


Subject to no further problems   

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Remove tools

Download and run Delfix
Select the options as shown



: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article

I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)

If you do need to keep Java then download JavaRa
Run the programme and select  Remove Java Runtime.  Uninstall all versions of Java present
Once done then run it again and select Update Java runtime > Download and install Latest version



Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

CryptoPrevent install this programme to lock down and prevent crypto ransome ware



Malwarebytes

Update and run weekly to keep your system clean

Unchecky

Click on the link above to be taken to Unchecky.com
click the very large Download button.

Click Open folder
Right click on the Unchecky_setup and choose to Run as Administrator
Once open click the Install button.
Then click on Finish
Unchecky is now installed and will help you keep unwanted check boxes unchecked, this is a fire and forget programme 

It is critical to have both a firewall and anti virus to protect your system and to keep them updated.
