How to clean all the installers?

[q12]

 I keep the instalation software that i tested and i liked. I am doing it for years. I have a special folder with all my instalations kits, and i gathered in time somewhere like 200 perhaps. So when i have to reinstal my windows, i reinstall my usual software from that folder. Thats it's purpose, a backup.

 Some time ago, i received a troian, and i manage to clean it yesterday from my C partition and from windows too.  But i scanned my D drive also, where this folder i have with all the instalation kits. And nearly all the executables are found infected from this latest trojan and from other old ones i had in the past. I am a bit desperate about this situation because i can not get back the specific software versions i gathered anymore.

 Is there a posibility to clean all these installers? But not cleaning by deletion or quarantine, but cleaning the actual virus that is inside them/or/attach to them ? And leave intact my instalation kit, ready to use another time, uncorupted or damaged?

I used:  MalwareBytes free version and also AVG antivirus free version.  Both softwares didnt clean eficiently from windows. Only from boot scan.

These are the viruses that are infecting my installers:

win32: Gardih  (this was the latest one)

win32: Crypt-SJB [Trj] (this was the latest one)
win32: Evo-gen [Susp]
win32: Rootkit-gen [Rtk]
win32: MalwareX-gen [Trj]
win64: Trojan-gen
FileRepMalware
MSIL:GenMalicious-AAS [Trj]
BV: ExitWindows-K [Trj]
BV: Agent-BGV [Expl]
Other: Malware-gen [Trj]

Thank you !

Hello @q12 and

I would doubt most of these are real infections. Often an installer may have a wrapper on it or a packed installer that may cause some antivirus programs to believe they may be infected, in some cases it's a false positive.

Let's go ahead and scan your computer and make sure it's clean and go from there.

 

 

Please run the following steps and post back the logs as an attachment when ready.

STEP 01

• If you're already running Malwarebytes 3 then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• If you don't have Malwarebytes 3 installed yet please download it from here and install it.
• Once installed then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• Once the scan is completed click on the Export Summary button and save the file as a Text file to your desktop or other location you can find, and attach that log on your next reply.
• If Malwarebytes won't run then please skip to the next step and let me know on your next reply.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

• Right-click on the program and select Run as Administrator to start the tool.
• Accept the Terms of use.
• Wait until the database is updated.
• Click Scan Now.
• When finished, please click Clean & Repair.
• Your PC should reboot now if any items were found.
• After reboot, a log file will be opened. Copy its content into your next reply.

 

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

• Double-click to run it. When the tool opens, click Yes to disclaimer.
• Press the Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here.
• Please attach the Additions.txt log to your reply as well.

 

Thanks

Hello and thank you for the welcome mister Ron,
I wonder if a MANUAL way is possible of cleaning those 'infections'.

I will start doing exactly what you suggesting here. But i can't not wander where this wrapper you're mentioning could be located?

Here are all #1 to do. I attached files and screenshots.
And thank you so much.

#2 now:
AdwCleaner (database was updated already)  I made multiple scans since it went so fast.
Sometimes windows didnt like it , throwing some errors but it did its job of cleaning.

#3 FRST
(i never run this tool before) - this is for the first time.

 

Addition.txt FRST.txt

[AdvancedSetup]

Please download the attached fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST or FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

mister Ron, bad news, the virus is still lurking.

I want to continue our hunt, but tonight im too tired. Tomorrow i will be here again. Im hunting this virus for half a year in my computer, always changing and becoming more aggressive. Last week it became a trojan. But until then, my computer hosted it and we lived together quite ok.
First scan=virus, restart, then second scan and all clean.  Then with adwcleaner, the same as other time, 2 times scan and the same result as in image.
We will continue tomorrow. And super thank you. You are the best !

[AdvancedSetup]

These are not virus. Just some minor threats at this point. Go ahead and reboot the computer and run a new Malwarebytes Threat Scan and post back the log please.

 

[q12]

I dont think are threats since its very active here. Every executable is attacked. I did the scan with MW AV. After i restarted, I tried to open adwcleaner, but it got 'infected' too(see photo i atached). And I can not execute it again (from a copy), even if i change its name.
That svchost.exe is the active virus(see photo). I manage to delete it manually a couple of times in the past. It was firing a service. But it keep coming back, reactivated by something more obscure. This time, MB detected it and quarantine it, for my surprise(see photo). It only show it in simple manual scan. Very strange he manage to do it. Only AVG catch it live and quarantine it. Also with AVG i could bootscan and clean the whole windows to 0 infections. But when i execute something from (anywhere actually) my D drive, any installer i mean, to put back my missing/damaged old software, this svchost.exe is reactivated again. It is not active by itself, but from events like me executing a software. I bet (but im guessing big time) it is probably activated even from simply opening a software like my browser, or startup applications. My initial post here was if those D drive installers are infected, for a moment i really panicked. But i didnt believe it so you confirm it saying its a wrapper of some sort, and i believe you. I am extremly curious where that wrapper is located. My best guess in registry... Since here as a simple file... it can't be so omnipotent. Or another wild idea that i very much believe it can be it, a hacker, through some sort of backdoor. He is getting feedback and then choose what to atack next. Very, very strange things with this virus i have here.
Thank you so far.

Please run STEP 3 and post back the 2 requested logs.

It looks like you probably have at least one or more core OS files that have been compromised and we need to check and get them replaced if needed.

Do not use files from your D:\ drive for anything until we get this resolved.

Thank you so much mister Ron. Your help is really an eye opening and it was a pleasure to get advice from you. Really.

But i was panicking more and more, since this infection i got was much aggressive by the minute. Truly, I had to react quickly enough since everything i was doing was starting to be intercepted and I was overwhelmed and very scared too. Scared for my D drive installers, not for windows files.  I talked with some programmers on a forum i circulate, and i trust them enough. They suggest me to reinstall windows quickly and not dangle around too much. I knew it too, but i tried to understand it better. Virus 1, me 0. So...  I reinstalled my windows now, all the software from D drive are very fine. I mean, some have some cracks in them and (MAYBE) they are a bit corrupted but super easy to scan and clean after them if is the case. 

I will give you a personal quest to try.  In my search for an alternative Firefox, like 1 year or so ago, i installed Waterfox browser. From that moment, i've always had a ton of weird movement in my system. I observe it little by little, in time. Nothing serious for a long time. But i think that thing is a portal from a hacker. Its my subjective impression and i can be wrong. I think i am not but, thats the quest for you.  Try to find out if its something dubious with that application or not. If im wrong, then shame on me not seeing too well the obvious. But... all my money on that, yes. And also other risky stuff i installed too, but that thing, ah... I swear.

Another wild curiosity... is  there such a thing like a " mutating virus" ? That is not only atacking/or/attaching to some installers/executables, but read the target, analize it, and modify its structure from inside? Is this a possibility today or is a nice imagination meant to scare the crap out of undocumented?

Again, it was a pleasure to communicate with you, and im sorry to interrupt our little hunt.

[AdvancedSetup]

There is nothing wrong with the Waterfox browser as far as an infection. It is an open source browser and perfectly safe. Whatever infected your system came along later on.

I'll go ahead then and leave you with some information to help keep the computer clean going forward.

 

Let's get real. If you're not backing up your data and you're still using Google Chrome then you're just not serious about Privacy, Safety, and protecting your data. Malwarebytes is a fantastic program but you still need to back up your data and you still need to block scripts and Ads in your browser. 
If you're still using Google Chrome I would highly suggest you consider using Firefox instead. For more advanced users you might consider installing NoScript as well (it does have a higher learning curve though)

 Yah, I am actually a Firefox user from it's beginings. Chrome is for childrens,  but very good for immediate problems to resolve if you dont have the 'master' browser installed. I just find out about Firefox Developer Edition. Its version 68 now and its allowing Extensions, that i'm actually after, to make it as personal as before, but i do a big fight with this aspect since they literally changed all the old file extensions. I barely could import my old data into the new 'format' if you like.  But too much about firefox on a AV forum.

I will take your advice and look into NoScript and  uBlock Origin that you mentioned, soon enough!  And I am backing up all my software now. I got a memorable experience and i have space too on my ext hdd.

You didnt told me about "mutating viruses". True or false? or in the middle somewhere?  Because if its True, we are truly in real danger with our files. Just saying.

Yah. thats it. I will (maybe) reply after reading your sugested literature. We'll see.
