cmpoffer.com redirect adware

[dd719]

Hello, I am a Windows user running Chrome and am experiencing browser redirect malware. The first time I click on a link on any page, it often will popup and navigate to a page for example: http://cpmofferconvert.com/out?zoneId=968177&htatb=1&sId=968177. Also, after a Google search, it will promptly but visibly change the sponsored results (the top 2-3) to something of its liking.

Steps taken so far

Malwarebytes Premium Threat Scan

• Results: mwbthreat01.txt (see attachments)
• Quarantined all successfully
• Restarted
• Results: mwbthreat02.txt (see attachments)
• Redirect problem observed

Farbar Recovery Scan Tool

• Results: Addition.txt, FRST.txt (see attachments)
• Will update if issue is still observed

Hello dd719 and  Forums.

My screen name is Android8888 but if you wish you can call me Rui which is my real name. I will be helping you with your malware issues. Please ask questions if anything is unclear.

I suggest printing out each set of instructions or copy them to a Notepad file and reading the entire post before proceeding. It will make following them easier.

Please DO NOT run any tools on your own and follow the directions in the order listed.

Make sure to run all the tools from the Desktop and with Administrator privileges.

Going over your logs I noticed that you have Torrent installed.

• Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs.
• They are a security risk which can make your computer susceptible to a wide variety of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites.
• Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users.
• The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.
  

It is pretty much certain that if you continue to use P2P programs, you will get infected again.
I would recommend that you uninstall Torrent, however that choice is up to you. If you choose to remove these programs, you can do so via Start > Control Panel > Programs and Features.
If you wish to keep it, please do not use it until your computer is cleaned.

Hello dd719 and thanks for those logs.

It's good to hear that the redirects disappeared.

You did not attach the Jumkware Removal Tool log, it is located on your computer's Desktop. Please attached it in your next reply.

Next, we will check for leftovers.

Please scan your computer with ESET Online Scanner. This is a very thorough scan and it can take some time to complete but it's worth it.

• Click on this link to open ESET Online Scanner in a new window.
  
  1. Click on the Scan Now button to download the esetonlinescanner_enu.exe file. Save it to your Desktop.
  2. Close all your programs and browsers.
  3. Please disable your antivirus program to avoid potential conflicts, improve the performance and speed up the scan.
  4. Double click on esetonlinescanner_enu.exe to start ESET Online Scanner. It will open a window with the Terms of Use.

• Check mark Download latest version of ESET Online Scanner and click the Accept button.

• 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: If nothing is found, it will not produce a log.

Please re-enable your antivirus program.

 

Please download Security Analysis by Rocket Grannie from here

• Save it to your Desktop.
• Close your security software to avoid potential conflicts.
• Double click RGSA.exe
• Click OK on the copyright-disclaimer
• When finished, a Notepad window will open with the results of the scan.
• The log named SALog.txt can also be found on the Desktop or in the same folder from where the tool is run if installed elsewhere.
• Please copy and paste the contents of that log in your next reply.
  

Note: If you get a Warning from Windows about running the program, click on More info and then click Run Anyway to run it even though Windows says it might put your PC at risk.

Please post the contents of Junkware Removal Tool (JRT.txt), ESET log (if it produced one) and SALog.txt and let me know how is the computer running.

Thank you.

[dd719]

Again, thanks for your reply!

The JRT log popped up an a completely blank document when it finished, so I won't bother attaching it.

Computer has been running for about three and a half days:

Hello dd719.

Thank you for posting those logs.

ESET found some PUA (Potentially Unsafe/Unwanted Application) and deleted them all so at this point I can say your computer appears to be free of malware.

It's time to get some updates. Outdated programs contains security vulnerabilities that are exploited by malware in order to infect the computer without the user's knowledge. Usually this is one of the ways that more contributes to the infection of your computer.

Please update Mozilla Firefox browser. The latest version is 53.
How to update Mozilla Firefox to the latest version

Then, remove the old versions of Mozilla Firefox through Start > Control Panel > Programs and Features.

Your version of Java is outdated and needs to be updated to take advantage of fixes that have eliminated security vulnerabilities.
The latest version is Java 8 Update 131.

You can manually check your present version and update as recommended.
https://www.java.com...d/installed.jsp

Be careful not to install malware posing as Java update!
Important read this blog.
http://blog.trendmic...java-0-day-fix/

If present remove the old version(s) of Java through Start > Control Panel > Programs and Features, if you are not developping Java programs.

Next,

If the updates went well you can delete the tools we used in the malware removal process using DelFix.

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 Run as Administrator;
• Check the following options :
  
  • Activate UAC (This option will activate the User Account Control feature).
  • Remove disinfection tools (this option will remove the tools used in the cleaning process).
  • Create registry backup (this option will create a backup from the Windows Registry).
  • Purge system restore (this option will remove all previous and possibly infected restore points, and will create a new and clean restore point of your system).
  • Reset system settings (this option will reset any system settings back to default that were changed either by us during cleansing or by malware infection).
    
• Once the options mentioned above are checked, click on Run;
• After DelFix is done running, a log will open. Please copy and paste the entire content of the output log in your next reply;
  

 

Please post the contents of DelFix log and let me know if you are still having any issues or concerns with this computer.

Thank you.

Hello dd719.

I'm glad your computer is running well.

To help keep malware off your system below I have included a number of recommendations for how to protect your computer in order to prevent future malware infections. Please consider using these ideas to help secure your computer.

Keep your Windows Operating System up-to-date.

Keep your AntiVirus program up-to-date.

Please note: Many installer offer third-party downloads that are installed automatically when you do not uncheck certain checkboxes. While most of the time not being malicious you usually do not want these on your computer. Be careful during the installation process and you will avoid seeing tons of new unwanted toolbars in your favorite web browser.

Keep Malwarebytes Anti-Malware (MBAM) update and perform a regular scan to your system as it will make it harder for malware to reside on your computer.
A tutorial on using MBAM can be found here and a complete guide here

Please Note: Only the paid for version has real time capabilities.
A free non-resident utility to prevent the installation of ActiveX-based malware is JavaCool's SpywareBlaster, available here

Please keep these programs up-to-date and run them whenever you suspect a problem to prevent malware problems. A number of programs have resident protection and it is a good idea to run the resident protection of one of each type of program to maintain protection. However, it is important to run only one resident program of each type since they can conflict and become less effective. That means only one antivirus, firewall and scanning anti-spyware program at a time. Passive protectors, like SpywareBlaster can be run with any of them.

Note that there are a lot of rogue programs out there that want to scare you into giving them your money and some malware actually claims to be security programs. If you get a popup for a security program that you did not install yourself, do NOT click on it and ask for help immediately. It is very important to run an antivirus and firewall, but you can't always rely on reviews and ads for information. Ask in a security forum that you trust if you are not sure.

A similar category of programs is now called "scareware." Scareware programs are active infections that will pop-up on your computer and tell you that you are infected. If you look closely, it will usually have a name that looks like it might be legitimate, but it is NOT one of the programs you installed. It tells you to click and install it right away. If you click on any part of it, including the 'X' to close it, you may actually help it infect your computer further. Keeping protection updated and running resident protection can help prevent these infections. If it happens anyway, get offline as quickly as you can. Pull the internet connection cable or shut down the computer if you have to. Contact someone to help by using another computer if possible. These programs are also sometimes called 'rogues', but they are different than the older version of rogues mentioned above.

Another most feared threat at the moment is an infection by a Ransomware. A Ransomware infection is a program that ransoms the data or functionality of your computer until you perform an action. This action is typically to pay a ransom in the form of Bitcoins or another payment method. I advise you to read more info on this terrible threat here and here.

Please keep your programs up to date. Vulnerabilities are often exploited in order to install malware on your PC.

Run a program like Personal Software Inspector (PSI) or FileHippo Update Checker to see what programs need to be updated.

Be careful with flash drives, as they can spread infections. See this post on USB/flash drive safety.

Stay away from P2P software; even with a clean P2P program, their networks are often riddled with malware.

Don't click on attachments or links in e-mail, and read your e-mail in text-only mode for the highest safety.

Don't click on links received in instant message programs.

A HOSTS file will prevent Internet Explorer from communicating with sites known to be associated with adware or spyware. A good regularly updated HOST file is MVPS HOSTS File, available here

For much more useful and complete information, please read the following links to fully understand PC Security and Best Practices:
So how did I get infected in the first place

Hopefully these steps will help to keep you error and malware free. If you run into more difficulty, we will certainly do what we can to help.

Happy surfing and stay safe.
