DKSERVICE.exe is installed with Executive Software Diskeeper. Is this something you know about and have installed?
If it is legit then you may like to consider reinstalling this .exe file from a program disk.
I can find very little on Rnapp and nothing in English. You may be right suspecting an infection but, without being able to get online, it may be difficult to sort this out.
I am guessing you have access to a computer online (otherwise you wouldn't be posting this) so I suggest you try this.
Using a computer that can get online download Ewido/AVG Anti Spyware from here to a disk ….
http://www.ewido.net/en/It has a fully working 30 day trial period.
Install it on the suspect computer.
Do
NOT use it yet.
Boot the infected computer to safe mode.
When in safe mode run a full system scan with AVGAS and let it fix what it wants to.
REMEMBER TO SAVE THE SCAN REPORT and also remember
where you saved it.
[FOOTNOTE > this is a good program to use as an “on demand” scanner even after the trial period is over. Keep it updated and use it to scan your computer from time to time].
Now try rebooting the suspect computer into normal mode and using it as you would usually do.
Post back and let us know how you get on. Any improvement?
