lol.... i wish i had 1 tb of memory
i think you probably do have a virus
You should scan you computer for viruses
I would use malware bytes, but if the problem continues
Boot CD - go to these places, download, and burn the ISOs to CD's.
AVG Rescue CD
Kaspersky
Comodo
Put one of the disks you make from these in the DVD drive
Restart the PC
When it asks to boot from CD or DVD, say yes (or press any key)
Follow the instructions and clean any viruses it finds
Repeat for the others
