VIRUS? Hi, My internet connection drops and Oracle local DB connection drops too..

VIRUS?

Hi,

My internet connection has been dropping spiratically after a few minutes and I have been blaming the internet provider.
But now I'm trying to use simple commands in the SQL Worksheet and they workd one time then the same commands don't giving ORA-12571: TNS:packet writer failure

I connect with my connect string:
Connect bill/xxxxxx@stdev
Connected.

SHOW PARAMETER SHARED_POOL_SIZE
ORA-12571: TNS:packet writer failure

SHOW PARAMETER SHARED_POOL_SIZE
ORA-03114: not connected to ORACLE

the connection with the database ALSO drops spiratically

Is there a virus that does this? Either way what do I do?

Thanks, Bill
