I have reinstalled and reformatted, but I want to check if any viruses still remain. Please have a look at my logs.
Ant moving on screenthere are screensavers doing this .....
There are also websites that have show that.
The logs don’t show anything harmful as would be expected since a format will (or at least should) wipe everything.
I do recommend to install McShield though.
After I plugged in a USB, McShield had a log which showed 7 suspicious files that had been renamed. Should I be concerned?
Not anymore, fixed by MCShield 
That is a relief.
