Right, I think I've picked up something. I'm sure my highly outdated Explorer didn't just evolve into some mutant. It's currently opening up random pages on the internet. I ran avast!, but it doesn't pick up anything at all, asides that whatever is going 'round, it trying to DL other crap as well. Which is getting blocked, by the way.
I've been looking in my PC for recent downloads, but so far I've only found legit things.
Now I'm not very familiar with all of this and can honestly say I have no idea what to do to either find this thing, whatever it is, and kill it, or just swipe the whole PC and begin anew. Prob is, the latter will cost me a lot of information and happily installed programs that might take up to a day or two to reinstall.
As you can guess, I rather not swipe unless I have no other options left.
Any help at all that doesn't become too technical will be highly appreciated.
