Uh-ow..... Coolinfo heeft wat geschreven over de 'new and nasty variant of the original CIH virus'
CIH 1.2 is a file virus that infects Windows 95/98 EXE files, and infects your PC when the application is run. It's a relatively new and nasty variant of the original CIH virus, which first appeared in May of 1998, and received widespread publicity at the time. The original CIH triggers on the 26th of every month, but never became widespread. The latest variant, however, is considered to be common, and ranks 17 on Joe Wells' respected Wild List of viruses. CIH 1.2 is particularly nasty because it has what virus researchers call a dual payload. When it triggers, it first attempts to overwrite your PC's BIOS setup. This works only with a Flash BIOS that can be upgraded via software, and because there's no industry standard way of programming a Flash BIOS, CIH isn't always successful at doing its dirty work. But if it is successful, your PC won't start until the BIOS is reprogrammed. Whether or not CIH 1.2 is successful at overwriting the BIOS, what it does next is even worse. It overwrites your entire hard disk with random data, erasing all your data and applications.
