Or run the Recovery provided to restore the computer to day one. Then install the antivirus software. In this day and age, it is unwise to not have antivirus installed BEFORE connecting to the internet.
Lenovo running windows 7 got a virus today and will not let us access internet explorer, doesnt have any virus protection. How can I fix this problem? About a month ago it caught a virus too and I tried downloading AVG and it would not allow me to do so. Eventually I keep trying to download and virus seemed to go away. Now on the news today it said modems have been infected with a virus. So please direct me on what to do. Thank You!
