Thank you.

But what Can I Then do with "old" passwords? I logged on my iCloud account on the internet about a week ago, and I don't want any virus to get a hold on that.

Hi!
My sister used my pc to download some the sims 3 for free. I didn't really trust it, so I scanned my pc and didn't find any thing.
Can some viruses "slip" through the scanning?
And Can a virus find passwords from your browser history, even though I've deleted my history?

Hope you'll answer me:-)
