i can still access the internet and do everything normally but on the home screen of my computer there is a box and inside are words that say "your system has been infected" in red letters. please help. it is getting really annoying.
It's about certain it is bogus, so don't touch that box. See if you can download the freebie MalwareBytes and install it. If so, update it first then run it. It usually fixes those things.
We all live on a ball.
You have an unwanted rootkit installed. Try malwarebytes as suggested and post back if the problem is not resolved. Remove all that malwarebytes finds and then go to your display settings and reset your desktop background. Some HELP in posting on Computing.net plus free progs and instructions Cheers
