All anti-spyware sites are blocked

I can't remember what tipped me off, but something isn't right on my computer.  Current symptoms are that all anti-spyware sites are blocked and what I can download either won't run or can't get the updates in order to run.  I also have the problem of Google results linking to sites that aren't consistent with the link.  I have run a couple of things, rootrepeal and gmer, and they've noted MSIVX...dll and MSIVX....sys files as potential issues.  I've tried running scans in safe boot mode and while I can scan them, they don't resolve the issue.  Please suggest what steps to take next.
