xploreZip, the worm that devas-tated systems in June, is now back in a compressed version that is slipping through antivirus security systems. The worm has infected several major companies in the US, with Europe and Asia also being hit. The virus has infected several Australian companies. The virus hit Sabela Media and ninemsn mid last week, with both businesses reporting minimal damage. Many other companies, including KPMG, are also believed to have been infected. Gour Lentell, executive chairman at Sabela, said ExploreZip had corrupted "some files" on the file server. "We're recovering that from the tape backup now."
