Backdoor Bot MSIL?

Post by daddywhite on Wed 29 Oct 2014, 6:09 am

First topic message reminder :

Hi,

I wrote a small windows application for a friend in Visual Studio which would read his emails from outlook and filter out the specific ones he was looking for.

I built it, sent it to him and he said that MalwareBytes had reported that it was infected with "Backdoor.Bot.MSIL".

I ran the scan myself on the file and sure enough it apparently was. Everytime I built that specific project it was classed as "infected".

I created a brand new project in Visual Studio, copied the code, built it and this was NOT infected!

I am thinking perhaps it was a false positive, but I am a bit sceptical so can some help me thoroughly scan and clean my PC just to make sure?

Thanks in advance.

Regards
Dave

Fine - was running fine anyway, it was just that one issue with a file I created in visual studio. I assume in that case it must have been a false positive?

At this point, that's what it looks like. Let's clean up.

This step will remove all cleaning tools we used, it'll reset restore points (so you won't get reinfected by accidentally using some older restore point) and it'll make some other minor adjustments...
This is a very crucial step so make sure you don't skip it.
Download DelFix by Xplode to your desktop. Delfix will delete all the used tools and logfiles.

Double-click Delfix.exe to start the tool.
Make sure the following items are checked:

  • Activate UAC (optional; some users prefer to keep it off)
  • Remove disinfection tools
  • Create Registry backup
  • Purge System Restore Points
  • Re-set system settings

Now click "Run" and wait patiently.
Once finished a logfile will be created. You don't have to attach it to your next reply.
****************************************
Click Start> Computer> right click the C Drive and choose Properties> enter
Click Disk Cleanup from there.



Click OK on the Disk Cleanup Screen.
Click Yes on the Confirmation screen.



This runs the Disk Cleanup utility along with other selections if you have chosen any. (if you had a lot System Restore points, you will see a significant change in the free space in C drive)
****************************************
I suggest using WOT - Web of Trust. WOT is a free Internet security addon for your browser. It will keep you safe from online scams, identity theft, spyware, spam, viruses and unreliable shopping sites. WOT warns you before you interact with a risky website. It's easy and it's free.

Check out Keeping Yourself Safe On The Web for tips and free tools to help keep you safe in the future.

Also see Slow Computer? It may not be Malware for free cleaning/maintenance tools to help keep your computer running smoothly.
Safe Surfing!

All done - and ive installed WOT.

Thanks for your help - good to know I wasnt infected.

I'm pretty good and checking what I'm installing, removing any dodgy add-ons etc.. but you just never know.

Is the process we have gone through worthwhile doing on a regular basis?

Regards
Dave

You're welcome. I will lock this thread. If you need it re-opened, please send me a pm.

You may keep MBAM and AdwCleaner and run them on a regular basis.
