Help please! URL:Mal C\windows\explorer.exe

Viruses and worms
1

Hi I’m wondering if anyone could help me please!

Last night I got a warning through avast saying URL:Mal C:\windows\explorer.exe. I restarted it and my start menu has disappeared as well as some programmes on my desktop and on the right hand side it has “blocked startup programmes” software. My internet would not come up so I restarted it in safe mode and downloaded avast and malwarebytes again. The malware program identified two trojans and then I did another scan and it found PUM.hijack.startmenu - I removed these both and restarted again but my laptop is still playing up. I keep getting C:\windows\explorer.exe coming up and lots of pop ups keep appearing. I also had the blue screen of death 3 times (one was driver_irql_not_less_or_equal error and bad_pool_header error).

I’m really stuck as to what to do now and I really need help!

Thank-you for reading.

I tried to run aswMBR.exe but it won’t run at all. Any ideas why?

Thanks again.

Hey, thanks for your help! Everything seems to be running well (touch wood!)

Thanks again! :slight_smile:

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

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

[*]Click Start.
[*]Open My Computer.
[*]Select the Tools menu and click Folder Options.
[*]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:

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

Keep safe :wave:
