That's great she was able to clean it all out of your computer. It can be frustrating to have a big mess up.
I use Google Chrome and gmail and it cleans everything before it opens. I took my computer in to have more memory added and the guy said every scan he ran showed nothing harmful at all on the computer, my registry was clean as a whistle, and it's over four years old. All my email/docs/images/files/bookmarks are stored online and opened online, not on my computer, so there isn't much chance of any bad stuff getting in my computer files or registry. I can't tolerate a slow computer and this old one is still lightening fast, as fast as my DH's new laptop.
