Over the last several days whenever I log onto CFS it downloads a small application to my HD. (Win XP no SP).
This application then attempts to connect out to the internet.
It is caught by an outgoing firewall.
The application is only about 2kb and happens at every logon.
Each time it has a different name of about 7 jumbled letters.
Todays little application is called "obqszrj.exe".
I then have to go and manually search for this app on my HD and delete it.
Is this a feature or a trojan?
