If it suddenly popped up on your screen then that is potentially a virus IF you click it. Just click the red X on the flashing window and it should go away. But whatever you do, DO NOT click it. To prevent this from happening again, make sure you have a working pop-up blocker.
Congratulations! You have a virus. (:
A pop up is a virus that puts a window up on the screen. Most are harmless, while the more devastating "Are You Gay" pop up can destroy your computer.
you cant log in after a virus because it is messed up and you will have to restart it
A virus can potentially alter a computer screen resolution while disallowing any changes to the setting. Additionally, if a virus attacks the drivers used for the computers video card, this can also affect screen resolution.
get some anti virus software and keep your computer turned off because it lets the virus do more damage
From my experience, they screen every little file for virus codes. For instance, if something is trying to rewrite a file with an extended name into your System 32 file, the virus blocker will stop this rewrite and quarantine the extended file into a separate vault run by the software.

To do something what you don't want, and do not stop it's activity even if you want to stop. It's not necessary that virus should be harmful to be a virus. Some pop-up window downloaders are viruses but they do not harm anything except your internet traffic grows up.
lick the screen and electricute yourself
