Hello all,

 

For a few days I have encountered pop-ups from Avast, saying that it blocked websites hosted from svchost.exe.

I did some research on what this might be and the information you guys might need to help me. So, here it is:

 

  • The pop-ups come when I make connection to the internet (and thus when I start the PC).
  • In the pop-ups, Avast says that it blocked malicious websites, often named "simplesitescan" or "anythiago". It is classified as URL:Mal.
  • I am using Avast and Malwarebytes Anti-Malware as security.
  • I scanned my PC with both of them, but they didn't detect anything.
  • The pop-ups often (or always, I'm not sure right now) mention Google Chrome as a browser, it might have something to do with that.
  • I ran the recovery tool and the 2 logs you need are attached to the post.

I hope you guys can help me, because I am getting like 10 pop-ups everytime I connect to my internet.

 

With kind regards,

Carsten de Groot (Netherlands)

Thanks for your time and help.

 

The fix made my PC reboot and I haven't encountered the pop-ups while starting up the PC (and the internet).

 

To be sure, I've posted the log from the tool in this post, in case you might notice anything weird in the log.

These were the bad boys

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:

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 Save
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.
