How do you delete the virus on C System Volume Information restore EXE?
Wiki s contributors share some tips:
- All Trojan horses are hidden files so you would need to go to the Files Option (click the View tab) on the Control Panel and uncheck both the *Hide file extension for known file types & *Hide protected operating system files (Recommended)-boxes, then OK yourself out.
You will then need to restart your computer and and go into Safe Mode by holding the F8 key down (kind of at the beginning of bootup). When you're at the Desktop screen go to Start/ Search/ For Files and Folders and type up the NAME OF THE FILE & EXT (not PSW.Briss.C) but the actual name of the file, which would have shown up on your Anti-Virus software. You can delete this file from here, also make sure to empty your Recycle Bin.
I have had 4 Trojan horses on my C drive and kinda figured out the above method a week ago. I deleted the Temp file (as these keep putting the same files back into your system) from the Restore folder after unchecking the hidden files boxes, then went to Safe Mode to delete what virus files that were still there. My computer is now absolutely FREE of these pests!
I also have AVG 6.0 (the free one) & also the Ad-aware 6 and I use them every day as my kids love to play games from the Internet.
- I have Windows XP. This worked for me:
Open Control Panel Tools Folder Options View Uncheck "Hide protected operating system files" OK Start Search Files and Folders Enter all or part of Trojan file. Search Right click file when found Delete Empty Recycle Bin.
- Your virus scanner may not be able to access the folder because it does not have permission to do so. See this article for info on how to gain access to the System Volume Information folder:
http://support.Microsoft.com/default.aspx?scid=KB;en-us;q309531.
- I am running Windows XP Pro (build 2600) w/SP2 and on this system I am running Avast AntiVirus 4.5 Home Edition ( I alternate between this and Avast Professional when I reformat, which is 2x a year). This is an exceptional program as well as its brother Avast Professional 4.5, upon a daily scan the Home version found this: C:\System Volume Information\_restore{992476EB-89EC-4BBA-ACF9-063EFCB49378}\RP35\A0003426.exe Avast 4.5 Home Edition found and deleted this file, however to be sure I went ahead and did the following: Restart/Safe Mode/Administrator/Desktop/Start/Control Panel/Tools/View/Uncheck both 'hide extensions for known file types' and 'hide protected Operating System files (recommended)' click 'apply' then select 'ok' move towards start/search/all files and folders/*A0003426.exe search yielded nothing after Avast had initially deleted the file in 'normal' startup. I ran Avast Antivirus while in safemode and it came back after scanning the SVI Folder with clean results. Replaced the checkmarks back into the "hide extensions for known file types" and "hide protected Operating System files (recommended)", applied and ok'd, restarted and re-entered normal start-up. Since I was still bored I re-scanned in normal mode and again Avast found nothing. Well the bottom line is that I didn't have to do much other than carry out this exercise for when I may need to do so again and really have to work. Avast did most if not all the work for me from the get-go.
Azu shares a tip:
- Merely setting explorer not to hide extensions and protected files will not allow you access to the System Volume Information folder. You will not be able to open it and searches you conduct will ignore everything in it. To access it you must login to an administrator account, right click the folder, click properties, go to security, and add full control to it for your account. Only then will you be able to see what's in it. Unless you use the FAT32 filesystem, in which case this is unnecessary since it lacks privilege functionality.
How do you get rid of the stealth boot virus?
Run a couple of online virus scans
Run Malwarebytes Anti-Malware
Run a complete scan with free curing utility Dr.Web CureIt!
If you still have the problem you need to run
RootkitRevealer
www.Microsoft.com/technet/sysinternals/Utilities/RootkitRevealer.HTML
Sophos Anti-Rootkit
www.sophos.com/products/free-tools/sophos-anti-rootkit.HTML
And post your hijackthis log on a hijackthis forum (NOT HERE)
I'm not sure how to get rid of the stealth boot virus, I've never had it but I'm guessing that it opens during the boot process of your computer. One thing you could try is going to Start>run> and type msconfig. On the window that opens up go to startup then you can go to Google or some other search engine and type in the name of the startup items to see if any are not supposed to be there. Otherwise there are a couple programs out there that allow you to see what programs open at starup, you could find one that isn't supposed to be there. I hope this helps

I've found these a problem myself -my virus checker gets rid of them, but they pop back. A Google search took me to http://www.2-spyware.com/file-sui-exe.html which offers some free software to find 'Spyware' - since none of the antivirus sites I've looked at have anything to say about it. I haven't yet downloaded it yet, so I can't tell you if it works, but it is a possible option! 1. Delete the folder c:\program files\common files\updater and all files in it.2. Run regedit (Run Window). Drill into HKEY_LOCAL_MACHINE, SOFTWARE, MICROSOFT, WINDOWS, CURRENT VERSION, RUN folder. Remove the entry for "updater.exe".
Doing both of these steps will prevent the trojan from reinfecting your PC.
In addition to the updater directory in c:\program files\common files\, I found c:\updaterInstall_112.exe as being apparently responsible for creating the updater directory. Delete this .exe file also. Just found that if you scan with Norton it will find these files, sui.exe , wupdater.exe ect. and before telling Norton to erase them just press ctrl-alt-delete to access the task manager an in the processes tab , just highlight wupdater.exe and hit stop process. It will stop it letting the chance to Norton to erase it.The reason Norton cannot delete them is because it is running so can't be deleted.
Do the same with other.exe files you see in Norton scan and when all of them has been stopped, you can tell Norton to delete them and it will.
Try the following programs. They will stop all unwanted stuff from getting on your pc- I went to www.webattack.com and found a way to remove it by doing the following. I clicked on green link at the top of the page stating "FREEWARE", then clicked on virus tools/or you can search on that site for this program - "Avast home edition". It is the best freeware program, that i have ever used and removed the virus in no time. The Funweb A is a Trojan horse virus, and when Avast picked it up was going under another name - I think that's why everybody have difficulty in removing it, and can't find anything under funweb A because it is going under another name. Avast has also detected and removed 2 other virus infected files on my PC! It is important to do a live update of avast virus definitions and to set program to run a full system scan. Do download the full free home edition and not just the computer cleaner. It's AMAZING! Thank you so much Avast! Two programs going really well with Avast and also freeware on the same site is Ad-Aware spy detector and Zone Alarm firewall. I have all three and they work together like magic! Try it, you won't look back! I can confirm that Avast has picked up these trojans and another on one of my PCs despite me thinking I was fully defended. It seems to be considerably better than Norton although its not as user friendly to be honest. If you are a half way experienced user you should be fine with it, and for home use it's free!

Norton is junk. I fix computer every day and take out thousands of viruses and what I commonly see is Norton on the computer. That tell me that Norton is not working at all. Norton has lot of problem because it lives on your machine. New viruses come out by the second and Norton could not keep up with the update with its long distribution line and traffic jam up.

How can you remove Trojan MusicSearch.AM in a subdirectory under c system volume?
Assuming you mean a subdirectory under 'C:\System Volume Information' and your anti-virus application has detected but cannot fix the problem :- select System Restore tab in System Properties (WinKey+Pause) and check the box marked 'Turn off System Restore on all drives', confirm, close System Properties and reboot. This will clear all files in 'C:\System Volume Information' and therefore the MusicSearch.AM problem. 'C:\System Volume Information' is not just a hidden folder, it's also system protected and as such, anti-virus software cannot write to any file within and therefore cannot delete or quarantine any infected file detected. To turn on System Restore, just reverse the above procedure. Hope this helps, Canis.

Unfortunately, IM viruses have become a very common problem lately. Generally, removing these viruses can be complex, and removal instructions vary depending on which virus you have. More detail would be useful.
There are however some general things you can do:
1. Your best solution is to use a virus scanner. If the scanner does not detect the virus, it may lead you to a removal tool online.
2. If you know the name of the virus you have, a simple search on a virus scanner's web site (such as www.symantec.com) will probably lead you to an automatic removal tool.
3. Check out Microsoft's security web site at They have some tools you can use to remove many of these types of viruses, especially for MSN Messenger. You can look up other IM web sites to see if they have a removel tool available.
4. Spyware removal software, such as Ad-aware, can sometimes clean some types of these viruses. Check out www.lavasoft.com for more.
