Tiens j'ai récupéré ça sur internet, cela correspond au fameux .exe qui se lance dans ton dossier temp :
CoolWebSearch is a very tenacious hijack program that has gone through a lot of changes since it was first released. Each change is designed to make it harder to detect and remove, and the more recent versions have a backup system to keep you from deleting it completely. Some of the variants even use methods of hiding and running themselves that have never been used before in any other spyware. CWS uses two different processes that look for each other. If one process is stopped, the other one restarts it. Since it is also set up to load only when Internet Explorer is started, it is very hard to find the program in the 'usual' places (using msconfig.exe, regedit.exe, etc.) in order to remove it. Fortunately, there is a fix for this problem; CWShredder is available from SpywareInfo.com at http://www.spywareinfo.com/~merijn/downloads.html. (If you can't get to the site that way, try http://216.180.233.153/~merijn/downloads.html. Some CWS variants block the DNS for SpywareInfo). There are a couple of download formats available - as a zip file or an executable, and there is a link for the Microsoft VB6 runtime files if you need to install them (they are required to run the program, but chances are good that you already have them on your system). The author of CWShredder did not write the CWS hijack program. He even includes the following on the site: I did not create the Coolwebsearch trojan, nor did I hijack your homepage. It seems some sleazebags over at CWS think it's funny to redirect all complaints about their trojan to me. To get your homepage back, get my CWShredder. You have my word it will cure your computer and not install more junk. As someone who has used CWShredder on several computers, I highly recommend it to you if you have a hijacked home page, lots of new bookmarks added to your Favorites list, a problem with search engines being redirected to other search sites, and a host of other IE problems. But to prevent reinfection, you will need to get rid of the Microsoft Java Virtual Machine (MSJVM), which is being exploited by the CWS program. Microsoft will drop support for MSJVM as of September, 2004 , so it is a security risk just waiting for an exploit to hit it. You can uninstall MSJVM by following the directions at http://www.windows-help.net/WindowsXP/howto-21.html. After you have uninstalled the MS version, you will need to install the Sun Java software to replace MSJVM, and a free and painless download is available from http://www.java.com/en/index.jsp. If the uninstall does not work, or the entries mentioned are not there, you can install the Sun Java and then cekck to see that it is the default for Internet Explorer. Directions for this are on the Java setup page. Even if you do not have problems with hijacked homepages, et al, you should uninstall the Microsoft version and install the Sun Java software. A Meg of prevention is worth a Gig of cure!
