A tool that removes W32/Avril. #Trojan protection #Trojan remover #Virus protection #W32/Avril #Trojan #Protection
Resolve is the name for a set of small, downloadable Sophos utilities designed to remove and undo the changes made by certain viruses, Trojans and worms.
They terminate any virus processes and reset any registry keys that the virus changed. Existing infections can be cleaned up quickly and easily, both on individual workstations and over networks with large numbers of computers.
W32/Avril-A is an internet worm that copies itself into the Windows system folder using a random name and sets following registry entry to run itself automatically when Windows starts up:
HKLMSoftwareMicrosoftWindowsCurrentVersion RunAvril Lavigne - Muse = randomname.exe
The following registry entries are also created: HKLMSoftwareOvGAvril Lavigne=Done HKLMSoftwareOvGAvril LavignePSW-Trojan=1
W32/Avril-A drops itself into the KaZaA folder with one of the filenames shown below and creates the file avril-ii.inf.
The worm terminates anti-virus products and drops several copies of itself onto the hard disk with random names.
On the 7th, 11th and 24th of any month, W32/Avril-A will open up Microsoft Internet Explorer to www.avril-lavigne.com, display coloured ellipses in the middle of the screen and display "AVRIL_LAVIGNE_LET_GO - MY_MUSE:) 2002 (c) Otto von Gutenberg" in the top left corner of the screen.
The worm can send cached passwords to a Russian email address.
W32/Avril-A spreads by sending itself to email addresses gathered from DBX, MBX, WAB, HTML, EML, HTM, TBB, SHTML, NCH and IDX files, stored in listrecp.dll.
The emails will have the following characteristics: Subject line - randomly selected from one of the following 10: Fw: Avril Lavigne - the best Fw: Prohibited customers... Fwd: Re: Admission procedure Fwd: Re: Reply on account for Incorrect MIME-header Re: According to Daos Summit Re: ACTR/ACCELS Transcriptions Re: Brigade Ocho Free membership Re: Reply on account for IFRAME-Security breach Re: Reply on account for IIS-Security Re: The real estate plunger

W32/Avril-B is an internet worm which spreads via email. W32/Avril-B is an extended variant of W32/Avril-A. For information on the generic features of W32/Avril-B see the description of W32/Avril-A.
W32/Avril-B differs from W32/Avril-A as follows.

Message text - may contain one of the following 4 alternatives, but they might be skipped and hence not included:
"AVRIL LAVIGNE - THE CHART ATTACK! Vote fo4r Complicated! Vote fo4r Sk8er Boi! Vote fo4r I'm with you! Chart attack active list:"
"Restricted area response team (RART) Attachment you sent to is intended to overwrite start address at 0000:HH4F To prevent from the further buffer overflow attacks apply the MSO-patch"
"Network Associates weekly report: Microsoft has identified a security vulnerability in Microsoft� IIS 4.0 and 5.0 that is eliminated by a previously-released patch.

"AVRIL LAVIGNE - THE BEST Avril Lavigne's popularity increases:> SO: First, Vote on TRL for I'm With U! Next, Update your pics database! Chart attack active list .>.>"
Attachment exe - one of the following 21: ADialer.exe ALavigne.exe AvrilLavigne.exe AvrilSmiles.exe BioData.exe CERT-Vuln-Info.exe Cogito_Ergo_Sum.exe Complicated.exe EntradoDePer.exe IAmWiThYoU.exe MSO-Patch-0035.exe MSO-Patch-0071.exe Phantom.exe Readme.exe Resume.exe SiamoDiTe.exe Sk8erBoi.exe Sophos.exe Transcripts.exe TrickerTape.exe Two-Up-Secretly.exe
The worm may also attach a TXT, HTM, DOC or HTML file to the email from the Personal folder of the user.
W32/Avril-B tries to update itself from the web and also tries to download a backdoor Trojan (apparently Back Orifice 2K) from the web and run it on the user's computer. At the time of this writing the corresponding URL was unavailable. The worm would download the backdoor Trojan into bo2k.exe and set the following registry entry:
HKLMLSoftwareMicrosoftWindowsCurrentVersionRunSocketListener = bo2k.exe
W32/Avril-B drops a different version of the text file avril-ii.inf and sends the cached passwords to different email addresses.
The payload has also been changed slightly, in that the text displayed in the top left corner of the screen is now "AVRIL_LAVIGNE_LET_GO - MY_MUSE:) VOTE FOR I'm With YoU.
W32/Avril-C is a worm that spreads in local networks (see W32/Avril-A for further information) and on the internet by sending emails to email addresses gathered from DBX, MBX, WAB, HTML, EML, HTM, ASP and SHTML files. The sent email has the following characteristics:
Subject line - one of the following: Fw: IREX Fields Description Re: ACCELS Awards results for 2003 Re: Avril Fans will rock you Fw: Avril Lavigne - the best Re: Antique themes Re: ACTR/ACCELS Transcriptions
