I did a search -
virus internet monday
and it popped up all over by different names.
Apparently remnants of a hacker scheme the FBI caught up with last November may still affect some DNS Servers and many PC users are still affected. The affected PC's apparently get redirected to the rogue DNS addresses which ISP's were supposed to reroute to real IP's but the "temporary fix servers" will be turned off and affected PC's will no longer be able to access the internet.
Not to worry, though. Affected PC's can be repaired. Check yourself now our be prepared to check the PC's later or (shudder) pay the Geek Squad to do it.
This website calls it Alureon.
Above link provides this link to check and repair (if necessary) your PC. There's a very good chance that your AntiVirus/AntiMalware software already detects it.
FBI website calls it DNSChanger as does Computerworld.
This is Topic is more of an FYI heads-up to get a "checkup" by whatever means you have... See ya Monday morning...
