Malicious URL Blocked Message Keep popping-up

Avast Free Antivirus / Premium Security
1

Hi,

I am wondering if you can help me with a problem I seem to have picked up on my computer.

I keep getting the Avast Malicious URL Blocked pop-up which is happening every 30 seconds. This is really annoying and I am not sure how to go about cleaning my computer.

I have a Windows 7 Home o/s laptop (64-bit operating system). I ran Malwarebytes, rkill, CCleaner but the problem still persists. Please help.

Thanks.

Hi,

Here are the logs from current scanning. I haven’t seen the pop-up messages so far, fingers crossed!

Thanks so much.

8

Could you re-run TDSSKiller please as it did not complete

9

Hi,

Here is the re-run file for TDSSKiller.

Thanks.

10

How is the system now ?

11

It’s running smoothly, no pop-ups!

I am wondering if I should run these programs periodically, let’s say once a month to make sure everything is alright? Also, what was the issue with my computer, can you explain please!

Thank you guys so much for the great help, much appreciate it :slight_smile:

It was a trojan downloader, the intention was to download further malware, but Avast blocked it

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL
[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands [resethosts] [emptytemp] [Reboot]

[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

[*]Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
[*]In the Run box, type in ComboFix /Uninstall (Notice the space between the “x” and “/”) then click OK

http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg

[]Follow the prompts on the screen
[]A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

[*]Go to control panel
[*]Select folder options (Appearance > Folder options in category view)
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[]Click OK.

SPRING CLEAN

To manually create a new Restore Point

[*]Go to Control Panel and select System
[*]Select System
[*]On the left select System Protection and accept the warning if you get one
[*]Select System Protection Tab
[*]Select Create at the bottom
[*]Type in a name i.e. Clean
[*]Select Create

Now we can purge the infected ones

[*]GoStart > All programs > Accessories > system tools
[*]Right click Disc cleanup and select run as administrator
[*]Select Your main drive and accept the warning if you get one
[*]For a few moments the system will make some calculations
[*]Select the More Options tab
[*]In the System Restore and Shadow Backups select Clean up
[*]Select Delete on the pop up
[]Select OK
[]Select Delete

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

http://img233.imageshack.us/img233/7729/mbamicontw5.gif

Malwarebytes. Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

[*]Microsoft Windows Update

To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ?

Keep safe :wave:

Did everything as you suggested and it all went smoothly :slight_smile:

Thanks so much for the help Essexboy, you are THE BEST!!!
