evening;

got a problem with my laptop, be greatful if someone can help me

right, i think my laptop has got a virus as it wont allow me to download anything from the internet. if i click on save the file does not save anywhere, if i click on run nothing happens. this also happens in safe mode.

i have got AVG on my laptop, but this will not run in normal or safe mode, i cannot even run as administrator.

i have tried uninstalling avg but it comes up with an error.
