every time i turn on my computer, it lags like crazy, and when i try to go on the internet, it takes forever to load the page. sometimes it would have server busy and it would say the action can not be completed because the other program is busy... and it says switch, or retry as an option. if i press switch, the start menu cames up, and retry doesn't do anything. when the page is too slow to load, it just turns to an error page and it says internety speed monitor. i just got rid of this thing called mirar, but it didn't really do anything. i let my dad go on some sites for news,but i wasn't looking, so he did something i assumed, because it lagged a lot after. could this be some sort of virus? or something? how can I get my computer to normal? This has been the 4th day already
