|"....my problem is, that windows is not accessible, any command with ".exe" extention is rejected with pop up message "not supported", also any new application can not be intalled as its ".exe" command "not supported"."|
"If your .EXE files are not working then you are infected. "
You DO have malware on your computer.
Download, install, and run the free version of Malwarebytes. It will probably get rid of your malware.
See response 1:
Note that sometimes you can only install Malwarebytes in Safe mode - in that case, loading Safe mode with networking is required in order for it to be able to update itself.
Ignore the part about loading your latest System Restore restore point unless you did what the guy in that Topic said he did in the first post - loaded a previous restore point.
Regarding your mouse cursor freezing.
- Try a corded USB mouse. Usually when a USB mouse stops moving the cursor, all you need to do to is to unplug it and plug it back in again.
- Your ram modules may have a poor connection in their slots.
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
For a laptop, or netbook, you must remove both its main battery and AC adapter before you do that.
For a brand name computer, see the Owner's or User's manual if you need to - how to remove or replace the ram is usually in that - it may already be in your installed programs. If you can't get into Windows, it may be on a disk that came with the computer, or you can go online and look at it or download it - it's in the downloads for your specific model.
For a generic desktop computer, see the mboard manual if you need to - how to remove or replace the ram is usually in that.
If you have installed modules in ram slots that haven't had ram in them recently, there may be crap in the bottom of the ram slots that's difficult to see that you need to blow out of the slots, Use an air compressor and an air nozzle if you have access to one, or canned air or canned gas meant for cleaning up electronic circuit boards. (DO NOT use a vacuum cleaner to do that, unless you can rig it up to blow, without touching the laptop with anything connected to it.)
