It's the file C:\NULL\n\nSuddenly shortly after cold boot my fully updated(WinUp) and patched W98se\nPC reported the above noted infection. It's Grisoft free AVG with the\nlatest updates. This PC is also protected by ZoneAlarm, Belkin WiFi router\nwith firewall, SpyBot(resident). A normal Shutdown was done 12 hours\nearlier with no indication of any problems. There are still no indications\nof any problems EXCEPT that AVG claims it's found this trojan. There have\nbeen no floppy operations/mounts, no CD operations/mounts and no downloads\nand installs of anything since an hour before shutdown last night and now.\n\nFrom the DOS prompt I can see a file C:\NULL that has a 5/5/05 date. Since\n5/5 both a full manual AVG and Trend HouseCall 6 run have been done on this\nPC finding nothing.\n\nSo where and how did this file C:\NULL that AVG claims is Trojan horse\nDownloader.Generic.ML appear from? Was it really there since 5/5 but went\nunnoticed by both AVG and Trend HouseCall 6 and then this morning AVG\nsuddenly downloaded a new definition file which started seeing this trojan?\nOR did something penetrate all the firewalls and suddenly spawn this file\nwhich AVG quickly recognized?\n\nWhat likely happened here?\n\nThe operation I was in the middle of when AVG popped up was reading a text\nonly no attachment NG message in OE 6.00.2800.1123.
