Hello Essexboy
Have done as you said. Appeared a window in black with a list of eliminated files. Have closed immediately internet and zip prog.
It continued and after a while it rebooted the PC.
Then tried to enter internet and Avast page: same problem. Also with Microsoft page: always says server not found...
Tried to run it again but seems 'it ' has detected KK.

Have been trying to see why there is always a growing quantity of files to compress when I clean the disk. Found a file in System32 modified in the future (?) and a zip file with the same name.
Going to TEMP in Windows found 4 or 5 files (and it should be empty, cause I had just run the disk cleaning prog. and it was 0KB) (?) Have sent them to the bin. One of them says it's in use...(?)
I am also having problems with the clock. It gets back. Yesterday night left it OK, and now it was 10 hours back (!!).
Note. After loading KK. as you said, have tried to load KK from the link Onix gave, but couldn't open the page (same 'server not found').
