i really think it's from active X just to give you some feedback...i don't know how it's from active x thoguh because i got spyblaster... maybe i didn't update it in time.

Where is AVG finding this file??

[Edward]

argh idk now i removed it from the virus vault and now it's says when i do another search no viruses found... but i can sorta tell it's still there... my coputer is really slow..

[guestolo]

I'm not seeing nothing bad

Try this
Download and then Install
Ewido Trojan Scanner

When installing, under "Additional Options" UNCHECK  "Install background guard" and "Install scan via context menu".
When you run ewido for the first time, you will get a warning "Database could not be found!". Click OK. We'll fix that later
From the main ewido screen, click on UPDATE in the left menu, then click the Start update button.
After the update finishes (the status bar at the bottom will display "Update successful")
Close out Ewido
We'll need it later

Please Print this out or save these instructions to a Notepad file and save it to your Desktop
RESTART your Computer in SAFE MODE
You can do this by tapping the F8 key as the system is restarting, after the single post beep, or use the link
I supplied for a more detailed explanation

==Open Ewido trojan scanner
Click on the Scanner button in the left menu, then click on the Start button. This scan can take a while, so give it time to run
If ewido finds anything, it will pop up a notification. You can select "clean" and check the boxes "Perform action with all infections" and "Create encrypted backup" before clicking on OK.
When the scan finishes, click on "Save Report". This will create a text file.
Save the report

Restart back to Normal mode
Back in Windows, post the report from Ewidos
