Hi i recentky tried to go on youbube but when i clicked the link from google it redirected to me to another site the adress was something like www.computer- attack.tn.co something like that. On the site a box came up saying something had gone critically wrong ( sorry didnt get a screenshot) the tab was call security essentials. this happened once more but after clearing cookies i could go back on youtube. this happened in firefox, chrome was fine. Shortly after a i got this pop up from avira "In accordance with security guidelines, the Administrator has blocked access to the Hosts file." 

 

 

Can someone help me on what i should do next? i have ahd a few trojans in the past but i thought id got rid of them.

 

Thanks in advance.

Hello and welcome to BC,

 

Let's run some checks. 

 

Please download Rkill to your Desktop.
There are 2 different versions. If one of them won't run then download and try to run the other one.
You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

rKill.exe
http://www.bleepingcomputer.com/download/rkill/dl/10/
iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/
 

§  Double-click on the Rkill desktop icon to run the tool.

§  If using Windows Vista, 7, 8 or 10 right-click on it and choose Run As Administrator.

§  black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.

§  If not, delete the file, then download and use the one provided in Link 2.

§  Do not reboot until instructed.

§  If the tool does not run from any of the links provided, please let me know.

If normal mode still doesn't work, run the tool from Safe Mode.

When the scan is done Notepad will open with rKill log.
Post it in your next reply.

NOTE. rKill.txt log will also be present on your desktop.

------

 

Kaspersky Virus Removal Tool

Please download Kaspersky Virus Removal Tool from here.

§  Right click on KVRT.exe and select Run as Administrator.

§  Wait for Kaspersky Virus Removal Tool to initialize.

§  In the main screen, select Change parameters, place a checkmark in System drive, then click OK.

§  Click Start scan.

§  Wait for Kaspersky Virus Removal Tool to complete scanning.

§  When the scan is finished, select Neutralize all for all detected objects.

Please download Malwarebytes Anti-Malware (MBAM) to your desktop.

NOTE. If you already have MBAM 2.0 installed scroll down.

o    A 14 day trial of the Premium features is pre-selected. You may deselect this if you wish, and it will not diminish the scanning and removal capabilities of the program.

 

§  Click Finish.

§  On the Dashboard, click the 'Update Now >>' link

§  After the update completes, on Settings tab, set under Detection and Protection next options: 

1. 'Scan for rootkits'

2. Non-Malware Protection, for 'PUP detections', check, 'Threat detections as malware' option.

§  Return to Dashboard, click the 'Scan Now >>' button.

§  A Threat Scan will begin.

§  When the scan is complete, if there have been detections, click Apply Actions to allow MBAM to clean what was detected.

§  Return to Dashboard, click the Scan Now >> button.

§  A Threat Scan will begin.

§  When the scan is complete, if there have been detections, click Apply Actions to allow MBAM to clean what was detected.

------

Please 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, 8 or 10; 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.

Download Hosts-perm.bat from this link: http://www.bleepingcomputer.com/download/hosts-permbat/

 

 

  1. Download the hosts-perm.bat file and save it somewhere on your computer.
  2. Double-click the hosts-perm.bat file and when it is done you will see a message stating "The Permissions on the HOSTS file have been reset.".
  3. Press any key on your keyboard to exit the batch file.

 

Run again rKill and post new log.

Yes, it look fine now. Do you still have some problems?


I would like to help you to remove malware. Let's look inside.   :busy:

But I don't know to solve all PC problems.  :smash:

Great.

 

This step will remove all cleaning tools we used, it'll reset restore points (so you won't get reinfected by accidentally using some older restore point) and it'll make some other minor adjustments...
This is a very crucial step so make sure you don't skip it.
Download  DelFix by Xplode to your desktop. Delfix will delete all the used tools and logfiles.

Double-click Delfix.exe to start the tool.
Make sure the following items are checked:

§  Activate UAC (optional; some users prefer to keep it off)

§  Remove disinfection tools

§  Create registry backup

§  Purge System Restore

Now click "Run" and wait patiently.
Once finished, a logfile will be created. You don't have to attach it to your next reply.
