Hi,
- deletion can be done here by deleting all Temp.Internet.Files including offline files (all Programs and browser-windows must be closed)
- if it keeps coming back, either there's something hidden on your PC, or more probably, you get reinfected via unsafe IE-settings
-> Read the link "VirusRemoval" below in my sig, then..:
- secure your system & browser
- post a hijackthis Log-file
