I received multiple messages from Norton saying that a high risk intrusion attempt was blocked with IPS Alert Name of Web Attack: Suspicious Executable Image Download. After the blocked message, there were multiple IPS Detection Statistical Submissions. (I'm not sure how to post the entire Norton security history with complete details).

 

These messages came up as I was watching a video on acfun.tv and I have been using this website for a long time and have never received any sort of notification from Norton before.  All I had open on my Google Chrome Browser was reddit and the acfun video. It was towards the end of the video when these Norton alerts came up, but the video was still running fine and my laptop was running fine as well. I was also able to reload the video again on acfun again and didn't receive any Norton alerts.

 

I wanted to ignore this alert as I have seen a few posts with a similar issue and it seemed like the issue might have been on Norton's end in misidentifying the web attack. But on the other hand, I don't want to make any hasty assumptions and I want to make sure that my laptop is not exposed to any sort of risk.

That site according to Wikipedia does not store any of the downloads itself. So, depending on which video you select

to download determines which domain you are actually downloading from or streaming from.

 

You can use the programs below to clean up the computer and find and remove adware and malware. I good idea if you haven't

scanned your computer using them before.

 

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

 

Download Malwarebytes' Anti-Malware from Here

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).

  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • When MBAM is finished scanning it will display a screen that displays any malware that it has detected.
  • Click the Remove Selected button.
  • MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.

POST THE LOG FOR  REVIEW.

 

Download AdwCleaner by Xplode onto your desktop.

  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Scan button.
  • When the scan has finished click on Clean button.
  • Your computer will be rebooted automatically. A text file will open after the restart.
  • Please post the contents of that logfile with your next reply.
  • You can find the logfile at C:\AdwCleaner[S1].txt as well.
  • download Junkware Removal Tool to your desktop.
  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message
  • 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.

Hello Buddy and thank you for replying! 

I was streaming videos on the site and not downloading anything at the time either, so it was strange seeing those Norton alerts come up. 

 

Anyways,here is the MBAM Log:

-I'm kind of backtracking on my initial statement of not making hasty assumptions, but is it safe to assume that there isn't any problems and that it won't be necessary to do the rest of the scans? I had this happen before when I saw a Norton alert and started to worry. I was told to do some of those scans before and it turned out there really wasn't anything.

I suggest you continue with the other scans....of course....it is always your choice to make. As you can see

there was some adware removed by MBAM....just as rats...when you see one there is likely more nearby.

Ah I think that the adware might have come from GameGuard, which was installed when I downloaded Blade&Soul. 

I remember reading this thread about GameGuard and possible adware/rootkit before installing the game. 

https://www.reddit.com/r/bladeandsoul/comments/431zkv/gameguard_is_not_a_reputable_company_get_rid_of/

But I have never come across any of these errors or ads.

 

In any case, I will continue with the scans as you have suggested.

 

Here is the AdwCleaner logfile:
