Malware infection
« on: November 07, 2011, 02:47:44 PM »
Hi all.

Managed to infect my pc with some malware, constantly trying to link through to a dodgy URL. Avast keeps popping up to warn me every few minutes.

Have gone through the steps recommended at: http://forum.avast.com/index.php?topic=53253.0 and logs files are attached (MBAM.log pasted below. OTL, Extras, and aswMBR attached).

Could someone please have a look through and tell me if I have to do anything else, or am I in the clear?

Many thanks in advance!

Hi essexboy, mikael,

Thanks for the welcome and advice. Sorry took me a while to get back - have been off work!

Have run OTL again and attached OTL.txt and Extra.txt

No more symptoms have ocurred since I sent my last logs.

Let me know what you think please

Cheers,

Joe

Subject to no further problems   :)

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
    Quote
    :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
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.
   Your Java is out of date.
Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

 Upgrading Java:
  • Go to this site  and click Do I have Java
  • It will check your current version and then offer to update to the latest version
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 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:
