I recently reloaded Windows XP into my desktop, and after a few tweaks it was running OK. Then I used a flash-drive which unknowingly had a virus "rslwfk.pif" on it, which my laptop's AVG ID'd as a Win32.Sality dropper. Now the desktop can't boot in safe mode, and when I try to install an AV program from a clean flash-drive (I've tried AVG and Avira) it won't let the installation finish. It also deletes the icons for my CD-drives from the Computer screen, so I can't use the copy of Avira I have on disc.

How can I get rid of this thing?

Sorry about the error. The virus was ID'd by the AVG in my LAPTOP not the desktop, which at this time has no AV program installed. Since it isn't connected to the web, I thought I had time to get to that later, little guessing that I would infect the thing myself. I'd appreciate any help. Is there a way I can go to the MSDOS screen and control the CD drives, or go to the registry and remove this thing?

TO: BladeZephon

I started this thread on April 27, and have not received a reply. I posted a 'reply' of my own a day after posting it, to correct a previously un-noticed error. Perhaps I've ruffled some feathers at bleepingcomputer.com., but if so, I assure you it was unintentional.

Hamluis had previously attempted to 'help' me with a question, but as he himself stated, he was not that familiar with Vista, and he neglected to find out that when going into setup via the F12 key, as I did, no save options are given for any changes made in boot-device priority. If that dialogue was the problem, it is not entirely my fault. I may also mention that I had last used this site last year, and tried as faithfully as possible to follow the instructions given, but after 6 months (!) of endless (and fruitless) diagnostics copied onto my laptop and ferried over to the desktop under 'service', I was told to just reload Windows, being assured that I would lose no data, which of course turned out NOT to be the case. [The problem there was an inaccessible D-drive, which to this day remains inaccessible].

I sincerely apologize if any advisors were offended. I would just appreciate some help with this issue.

Thank you BladeZephon for this opportunity. I can only hope your level of objectivity exceeds that which I've previously encountered. :thumbup2:

Can you please perform the following: Disable Autorun and then try the following:

Hello,

And welcome to BleepingComputer.com, before we can assist you with your question of: Am I infected? You will need to perform the following tasks and post the logs of each if you can.

Malwarebytes Anti-Malware

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Full Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.

CP101 and Cryptodan,


WOW!~ That's a lot of info. Thank you both so much for the help! I mentioned in my post on the 29th that this unit is not connected to the internet. One of the things wiped out when I did the reinstall was my connection. I will attempt to make a new network connection today and will have to go to into town tomorrow and purchase some time for the (aircard) internet connection.
I live in Thailand, (land of poor service and slow ISPs) and have a broadband connection for my laptop, which does not seem to work with my desktop. The installers advised me I need some type of 'card', although the desktop works with a dial-up connection fine, just extremely slowly. 0-3kbps is the usual speed, although sometimes depending on the site being downloaded from, it may get up to a scorching 50-80kbps.

Then I'll attempt to download and run the programs suggested, and post the requested logs.

I will also cut and paste and print these instructions so that if this thread gets closed I can still attempt the repairs.

Thank you both very much for your help. :thumbup2:

I had an idea the other day, and bought one of those 'cases' for a 3.5" hard-drive with a power supply and USB connector. I pulled the HD out of my desktop and connected it to my laptop and ran a virus scan on it. I found 17 locations where the sality-dropper-virus-thing was hiding, and cleaned them all up.

Before I reinstall it, I wanted to try the trend micro housecall and the malwarebyte and superantisyware as well, but I wondered if they can be run on the HD like this, attached to my laptop like a big flashdrive. The reason I ask is that this internet connection is a better one than the one I must use with the desktop, which is sooooo slow that it always takes a long time to download any type of program.

Since the 'D' portion of the drive remains inaccessible, I wondered if these programs would be able to scan there as well, or only on the 'C' part, where the program files are.

OK, I downloaded Trendmicro and ran it in full system scan. It found a bunch of places infected, and then when I tried to have it fix them it told me the viruses either "do not exist or are inaccessible". I tried to disable my AVG program during the repair period, but it would only allow itself to be disabled for a max of 15 minutes at a time. ( I then tried to uninstall it, but it wouldn't allow itself to be uninstalled. Interesting.)Could it be that the program is finding 'traces' of the infected places that I cleansed with AVG the other day?
I've run the Trendmicro full scan twice today, the second scan found as many infected locations as the first, so it seems that it has not 'fixed' anything.

Now an hour later, I just finished the malwarebytes scan, and it says it has not found any infections, although the AVG screen kept popping up during the scan saying infections were found, and giving me the same response when I tried to have it remove them ("object does not exist or is inaccessible")

Here's the log:

http://www.safer-networking.org/en/spybotsd/index.html - go here & download Spybot Search & Destroy. Right click-Run As Administrator, Update the program and then run the scan. Remove anything found, tell me if it found anything.

Cryptodan,

Perhaps I missed something, but I didn't see where Trendmicro generated any logs. It didn't download a program per se, but just the installer. Each time I run it, it links to the web, downloads some components and then runs. But I don't see any logs. I will run it again today, and double check for one.

CP101, I'll try that program after I run the TM again.

BTW, when I first hooked my hard-drive-in-a-case up to the USB port and ran AVG, it found 17 virus locations, and I had it remove them. When TrendMicro ran, it found over a hundred, but a lot of them had the letters 'av' in their 'name'. Could it be that Trendmicro is seeing some type of trace of when AVG removed the sality virus from the drive? Or could it be scanning the AVG program, and identifying all its operational parts as viruses?
