Win32:Crypt-RQA [Trj], Win32:Enistery [Susp]

Viruses and worms
1

Hello,

I ran an avast security scan yesterday and it identified a file named 00032394.tmp located in C:\Program Files (x86)\SMINST folder as Win32:Enistery [Susp]. It was able to move this threat to the Virus Chest.

Like some other people have posted, Avast has flagged the file SYMEFA.DB located in C:\System Volume Information\EfaData as the trojan Win32:Crypt-RQA. When I initially tried moving it to the Virus Chest it told me access to the file was denied. I had Norton Internet Security installed on this system and removed it before attempting anything further. I changed the settings to show all of the hidden C: folders and when I right clicked on System Volume Information and said “Scan with avast” it again flagged the file as the virus, but this time was able to move the file to the virus chest.

My concern now is that I may have missed other files associated with the virus in the registry or other locations. Both Avast and Malwarebytes scans are showing no threats. I’ve attached the log files that are requested.

Any help with both of these issues is appreciated.

Thank you,

Avast is alerting on a Norton definition file in system restore, I will fix that at the end. Meanwhile I will remove what is left of Norton for you :slight_smile:

Otherwise it looks clean

OK lets now remove my rubbish and reset your restore points

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

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

: 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.

Thanks Essex.

Do I need to do anything with the files in Avast’s Virus Chest? Should I leave them there or should I delete them? Were either of them actually viruses or just Avast not agreeing with a Norton file?

Edit: The DelFix log contained this error:

Error when deleting (1) : HKLM\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_ASWMBR

Not sure if that’s a big deal or not.

The error is not a problem :slight_smile:

As for the files in the Avast chest you can delete them. Avast was alerting on the Norton definition file and was not a virus as such
