Heya, floba... no , don't worry about ATF cleaner, ccleaner does a similar job for our purposes.
You did not quite get the hijackthis instructions right, the new folder and name change are important items; adding [1] may not do the job. Your log shows clean, and it may be because of the unchanged name... try again,please.
Skip pressing the info button - that's all it is, a bit of info to explain things for you.
Did you run AVG AS? ..it would be nice to see the log.
And the exact error code would be handy to have... in your first posting it does not seem quite right.
And finally, dl and run Combofix:
==Download this file to your desktop: http://www.techsupportforum.com/sectools/sUBs/ComboFix.exe
...or from here: http://download.bleepingcomputer.com/sUBs/ComboFix.exe
- to run it dclick combofix.exe and follow the prompts to start it. When finished, it will produce a log, C:\Combofix.txt - post that log in your next reply.
A word of caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs, please reboot to restore the desktop.
So, please, we'd like to see an AVG log, combofix log, and finally make a new hijackthislog [with the .exe renamed!]
And the error code in full...
