I got an error message from Avast as follow:
Object: http://disorderstatus.ru/order.php
Infection: URL:Mal
Process: C:\Windows\SysWOW64\msiexec.exe
Please advise what I should do to stop this spam.
Thanks for your advice in advance.
After searching in this forum for a similar problem, I downloaded ZoeK and ran a script below:
createsrpoint;
autoclean;
emptyalltemp;
bitsadmin /reset /allusers;b
ipconfig /flushdns;b
The output from Zoek program is attached with this message.
Attach your basic diagnostic logs. (MBAM, FRST and aswMBR)
Instructions: https://forum.avast.com/index.php?topic=53253.0
Here are the log files as requested.
Did you run MBAM as well ?

Save this as fixlist.txt, in the same location as FRST.exe
https://dl.dropboxusercontent.com/u/73555776/FRSTfix.JPG
Run FRST and press Fix
On completion a log will be generated please post that
Yes, I did before ran other tools.
A fixlog file is enclosed.
Thanks
Have the alerts ceased ? It appears that MBAM took out the file as well as the registry entry this time
Yes, the alerts disappear after MBAM completed its scan.
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 
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
Select the options as shown

: 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:
Update and run weekly to keep your system clean
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 
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 
After 24 hours, the system is stable. So, I run Delfix as your recommendation.
Thanks very much essexboy for your help.
