Am o problema cand descarc ceva nu imi apare fisierul sub forma de rar exe sau bus imi apare sub forma de imagine ce trebuie sa fac ca sa imi mearga bine din nou?

Ai un virus care face sa nu iti mai recunoasca extensiile. Incearca asta.
1. Click Start, and then click Run.


2. Type "command.com", and then press Enter. (A DOS window opens.)


3. Type the following:

"cd\"

"cd \windows"

Press Enter after typing each one.

4. Type copy "regedit.exe regedit.com" and then press Enter.

5. Type "start regedit.com" and then press Enter.

6. Navigate to and select the key:

HKEY_CLASSES_ROOT\exefile\shell\open\command

7. In the right pane, double-click the (Default) value.

8. Delete the current value data, and then type:

"%1" %*

Tip: Type the characters: quote-percent-one-quote-space-percent-asterisk.

9. Close Regedit utility.


Note: If you are using Windows XP and you enable "System Restore", you need to
disable "System Restore" in "Safe Mode" before using the instructions above.

Incearca sa reinstalezi winrar, sau dai click dreapta pe fisier si selectezi open with... (deschidere cu...) ce vrei tu.
