Need help with a possible malware plz!!

Hello all!

I'm having an issue with my AVG A.V...
Every day a window pops up stating that an application is trying to access the internet(outgoing).. A "Setup/Uninstall"...
When I open up the "Show details" this is the file it shows: TSASETUP.TMP
(path: "C:\WINDOWS\TEMP\IS-4C5KC.TMP\TSASETUP.TMP)
I always click "Block" and the "Save me answer as a permanent rule...." as well but it still keeps on coming back.

I was looking for a solution on the web and came across 1 of the treads that described a similar problem and I followed the same suggestion which sent me to Your malware removal page.
I followed all the steps 1 by 1, but it didn't solve the problem for some reason..
I have all the logs except TDSKiller and MGTools, these 2 had an error when trying to create a log (I'm not sure if I should be alarmed by this or not..).
MBAM did detect 5 and removed/quarantined them so I thought all been fixed, but the next day the same window poped up!

I include here a picture of said window (detailed view and certificate view opened as well) and the logs from those 3 programs the made any.

Please if You have time to look over them and see if You can find a solution to this problem let me know!

Thanks very much!
