Phone rings. Microsoft Windows users from Cambridge to Norway ask, "Is my computer safe? I heard about a virus called Poison Ivy or something."
I assure them (and you) that as long as reasonable precautions and safe habits are employed, you will be safe even though the government of Germany has issued a formal warning to temporarily stop its citizens from using the Internet Explorer web browser.
Microsoft is scheduled to release a critical security patch today that, when installed, will further reduce any potential threat from this brand of virus infections.
Whichever version of Microsoft Windows that you are using, please make sure that all latest critical patches are installed.
Ask your local IT support person, even if it is your local teenager for help, if you can not do this yourself.
