Yesterday I started getting ads when I clicked on my browser - it doesn't have to be a link I'm clicking, just any kind of clicking at all.  It seems to be trying to open popups as well, but my browser is blocking them.  Initially, it didn't happen very often, but it seems to be getting worse. Generally, the browser will act normally for a few minutes and then spawn ads (generally for... pc cleaning and virus removal software, haaa) for the next 3-5 clicks, and then go back to normal.

 

I'm using Google Chrome on Windows 10.

 

What I've already tried:

 

Malwarebytes AntiMalware - This tends to turn up two infected files (PUPs) associated with the Crossrider adware.  But no matter how many times I remove them, they just come back.

 

Hitman Pro -   This turned up a bunch of tracking cookies, but is currently coming up clean.

 

avast Browser Cleanup - When I start this, I get the following message:

The toolbar protector "lstartsurf" has been detected on your system. It is recommended to completely remove it from your system, otherwise the results of avast! Browser CLeanup might not be reliable.

However, even when I say to remove it, the same message comes up when I open it again.  Also, it seems to be unable to detect my Chrome addons, because the screen is blank even when I unhide the good addons.  It detects addons from the other browsers just fine.

 

ADWCleaner - coming up clean.

 

Spyboy Search&Destroy -  This won't even let me scan the system - the option is greyed out.  It also tells me I'm missing signatures, "including Adware-C.sbi"

 

Malwarebytes Junk Removal Tool - it removed some junk but not this, and not lstartsurf, apparently.

 

Not sure what else to try at this point.  Thanks in advance for reading/potentially helping with this.

Welcome to BC...

 

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars....especially Google.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

CCleaner - PC Optimization and Cleaning - Free Download

 

 

Try resetting Google Chrome and scanning with Eset Online Scanner. Suggest you uninstall Spybot S&D as it can interfere with other scanners.

 

You can restore your browser settings in Chrome at any time. You might need to do this if apps or extensions you installed changed your settings without your knowledge. Your saved bookmarks and passwords won't be cleared or changed.

  1. Open Chrome.
  2. In the top right, click the icon you see: Menu or More
  3. Click Settings.
  4. At the bottom, click Show advanced settings.
  5. Under the section "Reset settings,” click Reset settings.
  6. In the box that appears, click Reset. ​

 

  • Hold down Control and click on this link to open ESET OnlineScan in a new window.
  • Click the esetonlinebtn.png button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
  • Click on esetsmartinstaller_enu.exe to download the ESET Smart Installer. Save it to your desktop.
  • Double click on the esetsmartinstaller_enu.png icon on your desktop.
  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
  • Click the Finish button.
  • NOTE:Sometimes if ESET finds no infections it will not create a log.

First of all, sorry for the reply delay.  It's just hard to find time when I'm working, sorry sorry! 

 

Update is:  

-I ran CCCleaner, and after that Malwarebytes stopped detecting the adware.  However, when I ran it again after reopening Chrome, the infection had returned.

-I also reset Chrome's settings, and the ads continued to spawn.

-And I ran ESET OnlineScan, and it came back clean and did not create a log. 

 

So yeah, basically the same situation.  

 

(And thank you again!)

It may be something new..... that would be the reason all the programs used have not found the culprit.

 

Please follow the instructions in the Malware Removal and Log Section Preparation Guide starting at Step 6.

  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running FRST which will create two logs.

When you have done that, post your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs...start the new topic anyway. Explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.

After doing this, please reply back in this thread with a link to the new topic so we can close this one.

 

DO NOT bump your new topic. Wait for a response from one of the Team Members.
