I had one of those viruses where they pretend to be FBI and lock the computer. The tek who fixed it said it got in through Google Chrome (which I had loaded on my machine) even though I don't use it and use IE. Any comments?
Oh, and that double post thing has happened to me but only after I get an error saying it failed when it hadn't, and I repost.
If you did not use Chrome it did not get in through Chrome.
All software has various vulnerabilities at various times. Strongly supported software gets patched quickly after a vulnerability is discovered.
Some software runs even when you are not actively using it. Just an example, there was a vulnerability not too terribly long ago in Windows where a remote support mechanism could be used by a culprit, even though the user had not turned it on.
Chrome does not have anything running if you don't use it. Maybe it was on his list of software that was, either in practice or in theory, vulnerable to something akin to what your PC was infected with. But, if you (or someone else) did not use Chrome then the infection did not come through there.
No software is perfect and I do not want you to think that Google's Chrome is perfect. It is pretty good, but not perfect. However, what that guy told you sounds totally wrong, given what you said.
