Help with Win32 Powessere Virus Removal

Viruses and worms
1

Hello,

My computer was running extremely slow. Webroot Virus software was installed. The software identified a “threat”, but didn’t specify what the threat was.

Installed Malwarebytes and it located and removed PUP.Optional.SearchDonkey, PUP.Optional.InstallBrain, and PUP.Optional.SaveValet.

Installed Microsoft Security Essentials and it located Trojan:Win32/Powessere.A!reg and two of Exploit:SWF/CVE-2014-0515.B. MSE claimed removal was successful.

Ran MSE a second time and it located Trojan:Win32/Powessere.A!reg, Rogue: Win32/FakeRean, and Rogue: JS/FakeAlert. MSE claimed removal was successful.

Ran MSE a third time with the same results as the second time.

Malwarebytes was ran again and showed no threats.

Attempted to install Avast by CD after downloaded from another computer without success.

Logs from Malwarebytes, FRS64, and aswMBR are attached.

Thanks

The CVE-2014-0515.B has been patched by Adobe over 6 months ago.
Time that you update Flash (and perhaps also) other installed applications/plugins etc.

Before you install Avast you must uninstall Webroot

How is the computer behaving now ?

It seemed to be running faster last night, but I have not connected it back to the internet. I wanted to avoid potential issues in case the virus was still present and I was waiting on further instructions.

I can try connecting to the internet later today if that is the next step?

Thanks

Yes connect to the net as I believe I have killed it all :slight_smile:

Hello,

Everything appears good. An MSE scan showed no threats.

Thank you for all of your help.

In that case methinks I will send you on your merry way :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:

Remove tools

Download and run Delfix

: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article

I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)

If you do need to keep Java then download JavaRa
Run the programme and select Remove Java Runtime. Uninstall all versions of Java present
Once done then run it again and select Update Java runtime > Download and install Latest version

https://dl.dropboxusercontent.com/u/73555776/javara.JPG

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

CryptoPrevent install this programme to lock down and prevent crypto ransome ware

https://dl.dropboxusercontent.com/u/73555776/CryptoPrevent.JPG

Malwarebytes.

Update and run weekly to keep your system clean

Unchecky

Click on the link above to be taken to Unchecky.com
click the very large Download button.
click Save
Click Open folder
Right click on the Unchecky_setup and choose to Run as Administrator
Once open click the Install button.
Then click on Finish
Unchecky is now installed and will help you keep unwanted check boxes unchecked, this is a fire and forget programme :wink:

It is critical to have both a firewall and anti virus to protect your system and to keep them updated.

To learn more about how to protect yourself while on the internet read this little guide Best security practices Keep safe :wave:
