Hello everybody! I just have subscribed to this forum because I think this is a fine place to ask about troubles with Windows (XP). I have an indestructible virus every time I install Windows (XP but also tried Vista and the result was the same). And not only in my PC but also in my mother's PC also. The description of the virus is mostly like the famous recycler virus. I have registry entries for a user that usually begins with S-1-5-21-etc (a lot of numbers) plus a hidden folder in all the partitions like c:\recycler, d:\recycler, etc, with a folder that looks like a recycler icon and some entries (folders) with this user name (S-1-5-21-etc). Right now I am working in Linux (Ubuntu 9.04) and I have tried other distros of Linux (like Fedora 11) and in that scenario there are no problems. The virus is like a whole autorun system wich hides itself anywhere in the disk or the RAM of the computer. It keeps strange uneraseable files in some folders of "Documents and Settings" and it's behavior is varied (everytime I make a clean install of XP it reappears, first in the registry, then in c:\recycler and other folders and files, and the suffix of the S-1-5-21-etc changes to other extension of numbers, only preserving this prefix). The behavior of this virus is variable, maybe it mess the desktop, other times it breaks the Internet connection, sometimes uninstall drivers and change the resolution of the screen or make impossible to install software in general or specifically *.msi. It can disable services, one time the virus compressed all my executables. Also it can block the Windows Update function. I live in Uruguay, but I was using an english version of XP and I noticed that the virus knows the location of the classic folders and stuff like Desktop and My Documents, etc. So I switched to a Spanish version of XP Pro SP2. I have tried to make clean installations unplugged from the web, with all the software recorded on a DVD but it was useless. I have tried different type of antivirus and antimalaware (I purchased a version of a-Squared anti-malaware wich I consider an excellent option, but it doesn't detect it. But it has a section of "Hijack this" with a sub-section for tricky startup entries and I can manage to block processes that are involved in this situation. But the virus reacts in an aggressive way, like if it knows what's going on. I have tried a variety of antivirus (including Antimalaware Bytes, Spyware Doctor, and of course Combofix). I have used rescue disks like Hirens boot CD, Dr. Web Cure it CD, BitDefender rescue CD, 18cm utilities CD, Ultimate Boot CD, and a lot more, but I didn't have results. I have tried to erase the complete harddisk with DBan Wipe Disk (also some scripts run in safe mode, to delete all the registry entries of the virus and the files and folders involved) but it seems to move from disk to memory or something like that and it doesn't disappear. I tried (with Hirens boot CD to delete even the Bios, the CMOS, everything, but nothing was of use). Recently I changed my old 60 Gb disk for a new 1 Terabyte HD and installed Ubuntu with a virtual machine to host other operating systems like XP, Vista and other versions of Linux. And it was there again. So I don't know where it comes from. Any help about this subject would be really appreciated. My email address is Removed
if somebody wants to contact me there. I will be checking this forum anyway.
Thank you very much. Rafael Diament.
