Solution:

1-Reboot your PC by choosing "SAFE MODE" option
In the SAFE MODE, Uninstall all the latest applications that you have downloaded (from when your problems started, for me it was the last month so I removed all applications downloaded the last month).
It might not be all cleared yet, then goto each folders of those applications and delete all the remaining folders and files manually.
Ideally rename all .exe file to another extension before deleting it, I have seen before .exe file in trash being re-executed and move within another folder (another
behavior of a virus!)

note: If you don't use the SAFE MODE restart, trying to Uninstall application programs might not work, it would say you don't have the admin rights, or it would install instead of uninstall!!! or freeze etc...

2-Initiate a normal shutdown, then execute a normal restart. Everything is cleared!

3-You can then re-installed fixes, applications,... etc.


The cause that I think is:
-I had a virus previously detected by the antivirus, got it removed in quarantine. The virus detected was "TR/Agent.bpog"
But after when I downloaded applications, I started to have all kinds of problems. Every files seems to be corrupted or infected.
Running the antivirus does not show any viruses. I scanned with many antivirus tools...still no virus found!


/Hope this helps
