Hey, first off I'd like to say I'm new here and Im really sorry if Im breaking any rules in this post :flowers:



Whenever I try to use a search engine, I'm getting fake "sponsored links" added to the top, and almost every link I click redirects me to some site called "bestwebsearch.net" and avast antivirus pops up with virus warnings.

When I go to sites like youtube and try to log in, the login page just keeps loading forever but never actually loads anything.

Interestingly, the two problems above are only happening to internet explorer and firefox - Maxthon browser is working fine (that's what I'm posting with)



Another problem that started happening at the same time (so I'm assuming they are related) is any program I try to install is refusing to run. I double click the icon, get the hourglass cursor for a second and then nothing. I've tried going directly to the exe file to skip the shortcut, and still nothing. I opened task manager and looked at the process list, the exe name shows up for a fraction of a second and then disppears so either it's getting an error or something is killing the process.

Unfortunately, malwarebytes anti-malware (which was reccomended on this forum in the threads I searched before posting) is one of the programs that refuses to run. It seems to be happening to all of the programs that I'm trying to install.

The only two programs I have already that might be useful are avast antivirus and process explorer :thumbsup:

Edit:I ran an avast scan before coming here, it found 88 infected files and removed them all. The fake sponsored links and bestwebsearch redirection stopped (other problems still happened), but then about an hour later the fake links and bestwebsearch were back.




Sorry if that postwas hard to read, I'm sort of out of it (really tired) but any help I can get with this would really be appreciated, I can't format my computer because I have nowhere to safely back up all my data

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

When I run the program from safe mode it asks if I want to scan and I click ok. Then it pops up asking if I want to download the trial, I click the X and close that window.. then nothing happens.

did I do anything wrong? :thumbsup:


If it helps, here is the process list

taskmgr.exe
explorer.exe
svchost.exe
notepad.exe
svchost.exe
svchost.exe
lsass.exe
services.exe
winlogon.exe
csrss.exe
smss.exe
System
System Idle Process

I do not think you did anything wrong...

Try running the scan in Normal mode.

I started getting this after downloading a "free" game from Comcast. For me the Sponsored Links only shows up in Firefox, but on a tablet screen it takes up too much RE and I don't like being watched.

I hunted for weeks and ran every scan possible I finally found it last night. In the \Program Files\Mozilla Firefox\components\ folder is a DLL called gtdgprvrheqvtoa.dll. I couldn't delete it while it was running so I renamed it to gtdgprvrheqvtoa.dlx and rebooted then moved it to a quarantine folder called REAL CRAP, which it is.

I haven't had the problem since.

I know the scans I ran removed components, but I don't think it can run w/o the dll.

Hope this helps!

Craig
