Okay, here's my problem. Earlier today, after installing the most recent Norton Antivirus definition updates, as well as Ad-Aware's updates, I was notified later that evening that I was infected with the "Backdoor.Coreflood" trojan. At the time of Norton's noticing, I was told a file repair failed, quarantining failed, and that the file itself could not be deleted. (The file, and its location: "C:\Windows\System32\tapiperg.dll." All efforts to delete/etc' the file have since failed.) I tried the removal method offered by Symantec (found at http://securityresponse.symantec.com/avcenter/venc/data/backdoor.coreflood.html) and I tried turning to McAfee and downloaded their "Stinger" trojan solution, which, too, failed. I tried an Ad-Aware full-scan, which helped nothing; I also tried a Norton full-scan, too, which only reminded me that I've yet to make progress. I can't seem the find that ".exe" file that Symantec mentions, which, according to them, seems to work in tandem with the DLL file the .EXE spawns, or so I believe recalling. I've installed ZoneAlarm, which, I hope, should at least restrict what leaves from and makes it into my computer. I don't have the money to call Symantec, and I don't know anyone personally who could help, so I'm reaching out after searching through Google for the past 3 hours. (This problem of mine arose 7 hours ago.) If anyone could help me, I would be so appreciative... I'm somewhat desperate here, and I do need and am still seeking assistance to this problem. So, please, a little help? I thank any and all in advance who come to my aid. w.j. Rodrique p.s... My system's 2.4 Ghz w/258 MB of RAM, running on Windows XP, "armed" with a cable modem which ISN'T WORKING AS WELL AS IT SHOULD. If you should need any further information, please, just ask me. Thank you for your time.
