i m receiving thread message from avast again and again. Which is as following
avast!Web Shield has blocked a harmful webpage or file
object: http://disorderstatus.ru/order.php
infection: URL:Mal
Process: C:\Windows\SysWOW64\msiexec.exe
Attach your basic diagnostic logs. (MBAM, FRST and aswMBR)
Instructions: https://forum.avast.com/index.php?topic=53253.0
Ihave attached the requested files
Hi could you run FRST from the administrators account please
The only reason i ran FRST from my account was that the problem was encountered only in my account. Avast did not detect any threats while i was logged on to the admin account. I have attached the FRST logs, run from the admin account.
It may not delete if using a non-admin account
CAUTION : This fix is only valid for this specific machine, using it on another may break your computer
Open notepad and copy/paste the text in the quotebox below into it:

: 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

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.
