Open notepad and copy/paste the text in the quotebox below into it:

Save this as fixlist.txt, in the same location as FRST.exe

Run FRST and press Fix
On completion a log will be generated please post that
Hello, here the fixlog.
Thank you!
Could you confirm the alerts have ceased
Hi yes by the moment! Thank you very much!!! Any further alerts i’ll let you know.
PS: I analyzed svchost.exe with Metascan and it found Trojan.Girtk.TJS.nlms.mg on Filseclab. Should I worry?
No, because the infection was a bits task
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
