Did the website start with http or https or something else. If it was https, then you don't have to worry bcs those websites are legitimate and won't harm your computer. If it was http, then keep an eye out for suspicious activity. If it was neither of those, then I would be worried if I had some important stuff on my computer. If you have some sort of virus detector or something like that, it has like an 90% chance of finding the source and possibly blocking the download. If not, then you could be screwed. The easiest way of getting rid of a virus (if you don't have an anti virus thing) is to wipe the hard drive if you aren't into computers that much (and I'm talking about knowing the back end of the 'systems.') Once a virus gets in, it's too late to get a program to remove the virus. And one more thing, if you try to take it to an IT help desk, they will just say, 'sry we can't do anything about that without wiping the hard drive.'
