Tens of thousands of Americans stand to lose Internet service on Monday due to a malware virus that may have infected their computers more than a year ago!

Is yours one of them?  Probably.  Is there anything you can do about it?  Yes, but you have to act before Monday.

The FBI estimates that some 68,000 American computers are still infected with malware that spread through an advertising scam and allowed an Internet hacker group to control infected machines. Law enforcement officials set up temporary servers to make sure no one lost Internet access. These will be shut down on July 9 at 12:01 a.m. at which time all infected computers will lose Internet access.

More than 277,000 machines worldwide are still infected, although users may not have noticed the relatively minor symptoms, like slowed connection. The company managing the temporary services set up a website where users can run a check on their computer for the malware and follow instructions on how to get rid of it.

Slate put together a good guide on how not to lose internet access on Monday.
