Took most of the day to get in to delete WScript but got there in the end.
Ran fix.
Ran quick scan,log attached.
Still no access to control panel,but malicious pop up’s appear to have stopped.MalwareBytes is accessable at the moment.
Will log off and check for your reply in the morning.

You can now restore wscript form the recycle bin

Run MBAM and see if that restores the control panel

If not could you let me know what error you get

44

Hi essexboy,I am back again - got to love short notice business trips.
I have restored wscript and run Malwarebytes,only a quick scan though.
Still no control panel and no error from the Malwarebytes log.
Should I run a full scan instead ?
Regard’s,
Kym

45

No run Combofix again, but allow it to update if it asks

46

Will do and will report back,with log’s when done.
Kym

47

Control panel is now back,Malwarebytes appears to be functioning normally,everything else seems ok.
Combofix log attached.

48

OK that now looks good, combofix did all the repairs again ;D

Any outstanding problems before I tidy up ?

49

No apparent problems at this stage.
Kym

50

OK let it run as normal and if all is well tomorrow let me know and I will tidy up

51

I have been playing around with the pc over the last week or so and all seems fine.
The only thing I noticed was that Avast blocked MCShield from updating,specifically the file MCShieldDS.exe,which then caused MCShield to notify me it’s installatiion was corrupt and to re-install it,then Avast blocked it again and so on.Eventually ran an Avast update and MCShield re-installed and ran as normal.MalwareBytes is running fine,control panel works ok and no malicious software or website popups have appeared.
I am hoping everything is back to normal.

Grand, glad to hear that

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] [CLEARALLRESTOREPOINTS] [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.

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

If you use on-line banking then as an added layer of protection install Trusteer Rapport

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:

54

Will do.
Have Malwarebytes installed as well as avast! free.Will add File Hippo and double check the windows update settings.
Should I leave MC Shield on to help prevent further problems from portable drives ?
I have also purchased a Windows 8 laptop on which I have installed Malwarebytes.
It came with Norton Anti Virus pre installed and valid for 12 months (freebee from the retailer to try and sweeten the deal),shoukd I install MC Shield on this as well,just to be on the safer side ?
Much and many thanks to you and polonus and all the team at this forum for your assistance and advice :slight_smile:
