Some virus can do this kind of thing.
Do you have access to another pc?
If so, download malwarebytes anti malware program.
You can get this from download.com or just google for it.
Install, update then scan. Sorts most things out.

We have had loads round here.. i've managed to collect around 12lbs.. and have made some jam... and some wine.. and still have around 6lbs left in the freezer. Probably going to use this to make MORE wine :D
Just started brewing again after a 10 year break.
Got some young's barley wine bottled up and some blackberry and gooseberry wine bubbling away.
Happy times ahead
