Big Blue catches cold with PC virus

IBM has admitted that some of its PCs may be infected with the CIH virus, set to plague some of our systems later this month. That is, if we've bought IBM Aptivas, and the evidence is not many of us have. Big Blue said some Aptiva machines in the US were exposed to the bug during manufacture due to human error. IBM warned users to look out for model numbers 240, 301, 520 and 580 made between 5 and 17 March, with the codes after "MFG DATE": AM909, AM910 or AM911. The CIH virus trashes the PC's hard disk and is set to trigger on 26 April. ®
