Thanks mchain. In fact this has nothing to do with “Adobe” anything. Neither does it have to do with Chrome browser as it affects all browsers.

It appears to be a router infection. Some evidence suggests it modifies the ISP set by the ISP when the modem connects to DSL. So far I haven’t found any evidence that it actually did anything and I am hoping that one of the many protections in the computer would have caught it if it did. It just provided a rogue DNS so traffic to certain sites was diverted to rogue sites. So far, we’ve only had one model of router reporting this. (We haven’t identified anything much yet, but that’s the suspicion.)

Personally, I rely mostly on the avast! software updater which, with a few early glitches which were sorted out soon after release has turned out to be really good! At least one of the Adobe updaters always fails to update despite downloading the file and running it. Good old avast!
