Adobe Flash Update Browser Redirect Downloads Installer.exe


Recommended Posts

Hi, need help with an issue please.  When browsing the internet, my PC randomly (2 - 3 times per day) redirects to a website which says I need to update my adobe flash player and downloads a file "Installer.exe".  The website looks close but is obviously not Adobe.  

 

I run Norton Security Suite.  It immediately scans the file.  Sometimes is flags and quarantines the file.  Other times it says its safe.  I've been careful not to open any of the .exe files and to delete any that are not quarantined by Norton.  However, the browser redirects & downloads won't stop.

 

I've researched the issue online.  It appears this kind of issue can be due to PC malware or a router hack.  We run 1 PC and 2 Android Phones on a wireless router.  The issue only shows up on our 1 PC so I'm not sure if the source is our PC or router.

 

Our PC has Chrome & Internet Explorer browsers installed.  We use Chrome almost exclusively and have only seen this issue in Chrome.

 

Troubleshooting to date includes:

 

Belkin N750 Wireless Router - Factory reset on router, installed latest firmware update, changed router admin password.

 

PC (Windows 7 Home, Chrome & IE Browsers, Norton Security Suite) - Norton does not find any infections running a full system scan or a Power Eraser scan.  Malwarebytes Anti-Malware scan does not find any infections.  I installed and ran Adwcleaner today.  It found and cleaned a few issues.

 

I haven't had the issue happen again yet after running Adwcleaner today, but its only been a couple of hours.  I want to get to the source of this browser redirect and know its taken care of.  Please help!

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll be working with you.
 
     
    
Before we start please read and note the following:

  • Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
  • Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
  • Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
  • Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
  • Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
  • Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
  • Note that we may live in totally different time zones, what may cause some delays between answers.
  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

:excl: I can't foresee everything, so if anything unexpected happens, please stop and inform me!
:excl: There are no silly questions. Never be afraid to ask if in doubt!

Thank you for your help, TwinHeadedEagle.  I downloaded FRST64.exe from "http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/dl/82/". However, Norton immediately scans the file, says it is not safe, and has been removed.  It lists the threat name as "WS.Reputation.1".

 

Is this file truly ok to download and run?  Why would Norton flag it as unsafe?

 

Sorry to question, but I'm very cautious now with the recent issue on my PC.  Thanks!

FRSTis legitimate tools used by dozen of helpers like me everyday and it is perfectly Safe to use. Why is Norton picking it up, I don't know, I reported it several times to their support but it seems there is some reason they do not want to exclude this tool.

FRST.gif Fix with Farbar Recovery Scan Tool
 


icon_exclaim.gif This fix was created for this user for use on that particular machine. icon_exclaim.gif
icon_exclaim.gif Running it on another one may cause damage and render the system unstable. icon_exclaim.gif

 
Download attached fixlist.txt file and save it to the Desktop:
 
Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on FRST.gif icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please post it to your reply.

 

 

 

 

 

Next, restore your router to factory settings.

Ok, I ran the fix today and performed a factory reset on my router while my PC was restarting.  Fixlog.txt file is attached.


 


By the way, my original attempts to solve the problem noted in my initial post here did not fix the issue.  :(  Chrome redirected me twice today while I was navigating to this forum to download the fixlist file above.  I was able to snap some screen pictures of the redirect page & resulting Norton notice on my phone.  If those are helpful, I can upload.


Fixlog.txt

Pics attached.  Sorry quality is not great.  I was taking the pics quickly as the redirects & Norton warning came.  Again, all of this happened before I downloaded and ran the Fixlog yesterday...  

 

  • File 1 was the first redirected page.  I closed this quickly before any download started.  Yesterday was the first time I have seen this redirect page.
  • File 2 is a 2nd redirected website that opened as soon as I closed the first one.  This is the page format I have seen every time in the past.  Installation.exe file downloaded immediately before I could close this page.
  • File 3 is a picture of the Norton warning that popped up immediately after Installation.exe file downloaded.  I told Norton to remove this file.

 

So far after running Fixlog yesterday, I have not had any redirects, but I am keeping web browsing to a minimum as you suggested until PC is confirmed clean.

Downloaded and ran TDSSKiller as per below.  No objects were found.  Two reports were generated in C:\ drive.  Both are attached.

 

Reran Farbar Recovery Scan Tool.  FRST.txt and Addition.txt logs attached.

 

Between running TDSSKiller and the FRST, I had a small window open and say an update to Microsoft Office 2010 Starter was available.  I could select download or cancel.  I cancelled.  I did not have any browsers open when this popped up.  This window appeared legit, but I have never had such a notice for a Microsoft Office update before.

Yes, the website redirects seem to be random and not linked to any specific site.  They happen while browsing reputable, popular webpages. 

 

The Microsoft Office update window popped up automatically again today (yesterday 1st time, today 2nd time).  This pop up window does not appear to be a browser window.  Window title is "Click to Run".  I caught a pic of the window this time and attached.  I think this may be legit, but I did select cancel on this for now.

Yes, I followed the router manual instructions to do a factory reset, firmware update, & password change.  I did this once before posting here.  The last webpage redirect in Chrome happened after that (before post #8 above).

 

Since I completed your instructions in post #8 above (fixlist.txt + 2nd router factory reset), I have not had any webpage redirects.  Not sure if the issue was fixed or if I just haven't been on the PC browsing the web enough for it to happen yet.

 

Do you think the MS Office update notice I got yesterday and today are legitimate?

 

If it is the router, any advice or experience on how to resolve?  I've researched online quite a bit, but it seems like factory resets + firmware updates + admin password changes are the only option short of replacing with a new router?

TwinHeadedEagle, the Adobe Flash update redirects resumed tonight. :wacko:  It happened while I was on Pinterest clicking on a link.  I clicked on the link a 2nd time to see if it would do it again, and it did.  

 

Chrome goes to the correct website for just a second.  I can then see the browser redirecting through about 10+ addresses quickly in the bottom left of the browser window.  It ends on the Adobe Flash update page and automatically downloads the same "Installation.exe" file I've been seeing every time.  Norton immediately flagged and removed the file both times.

 

I tried the same link a 3rd time.  Redirects started, but I was able to hit the stop loading button on the browser to stop the redirects and view the webpage I wanted.

 

This thing is driving me crazy!   :(
