So You Got A Virus

Definition of a virus:

a software program capable of reproducing itself and usually capable of causing great harm to files or other programs on the same computer; "a true virus cannot spread to another computer without human assistance"

Definition of a trojan:

a program that appears desirable but actually contains something harmful; "the contents of a trojan can be a virus or a worm"

Same thing, right? Right.

Alright, you could get a virus in the most honest way possible... by that I mean by downloading something besides porn 🙄 You could've downloaded something interesting, like a little game you found somewhere that goes with Blender and it can contain a virus... this is an example of a trojan (speaking from experience 😟 ).


These are free utilities you can use to fix your computer. (Don't download them now and use them... read on for more information).

What I recommend is downloading these utilities now while your computer is not infected and saving these utilities on a flash drive.

In most cases, this would fix your computer... at least to the point that it's usable again (If the virus blocked you from using the internet, Task Manager...).

It is recommended that you disable all of the scanners on your computer (antivirus scanners, etc.) before running this utility.

This is another utility similar to ComboFix... it is recommended to run this utility in Safe Mode and all of the scanners disabled.

This beast is NOT a virus scanners. The results it provides are NOT viruses or infected files (at least not all of them are) so DO NOT check and fix everything there... you need to get the results analyzed (Read on to find out how). What it shows you are all the services and running files on your computer.

To determine which of the results are bad and which of the results are good, copy the contents of the log that it saves (and pups up in most cases) and paste them in the textarea of an HiJackThis analyzer.


Here is when you should start working on fixing your computer (If it is infected).

Copy ComboFix.exe from your flashdrive onto the desktop of your infected computer and rename it... doesn't matter what you rename it to, just make sure that the .exe is present at the end. If you still not sure just rename it to qvb.exe

Now make sure that all the scanners are turned off. If you're not sure how to turn the scanners of, check what scanners are running (just running qvb.exe would be fine, it will tell you to turn the scanners off and it will also tell you which scanners are running), then google 'Disabling my running scanner'... an example of the search would be 'Disabling Norton Internet Security'.

After disabling the scanners, run qvb.exe (combofix). It would take about 10 minutes at most (unless your computer is extremely infected).

Once this is done, you should run hijackthis.exe (BUT DO NOT FIX ANYTHING THERE YET). Once you get the log file open, select all of the contents, copy it, go to this analyzer, paste it in the textarea, press Analyze, check at which ones it says 'danger' (It will have a red circle and a white 'X' in that circle), then go to hijackthis, check those that have that red circle (or 'danger') and then click 'Fix Checked' at the bottom left corner.

If you're not sure about a process/file/service that is flagged as dangerous, copy the contents of the log file and start a NEW topic about it here.

Now, what's left to be done is turning on those scanners and running them. Run them to see if ComboFix.exe (qvb.exe) missed anything, and if they did, fix them using those scanners.

Don't forget to periodically run those scanners (at least once a month, unless your PC is acting up) to make sure to keep your PC clean. And stay away from downloading iffy stuff. If you download a movie, make sure that the extension is not .exe or anything like that... that it's .avi, .mpg etc. etc.

Be weary of unzipping zipped files (.rar, .zip, etc. etc.).

Oh and I forgot to mention that sometimes your computer might start acting up if there is a good collection of dust in the case and not because of viruses at all.

There was one time I made a thread here titled "My computer isn't collecting dust... it's collecting viruses" thinking I'll make a smart-a** titled since I was annoyed about my computer (didn't even think about the dust thing) when the actual problem was that my computer was collecting dust and not viruses 🤣

I usually clean out my computer about once a year as dust can hinder the performance of the fans which help keep the case cool. When things get too hot inside your computer case, it will not function as well. So usually whenever my computer doesn't seem to be acting as great as normal, I will first run a virus/malware scan, and then clean out the computer. For those of you who have never cleaned out a computer before I would recommend you ground yourself first, and to use air duster cans to blow out the dust, especially off of the fans. I would try hard not to really touch any parts. I usually have the vacuum cleaner running nearby to suck in the dust I blow off, but I do not touch the vacuum cleaner on anything inside the computer as I don't want to short circuit anything. I actually just cleaned a computer today 🙂

    This is good advice, if nothing else just to help the ears get some rest. My computer was sounding loud recently, I thought it was due to its age but then I cleaned the fans and its now "very" quiet. So if a computer makes a lot of sounds it may be due to dust. — WritingBadCode

Microsoft Security Essentials is free to all genuine Windows users.

    Worth noting about MSE is that it don't offer full functionality under windows XP since it only offers its network intrusion detection system only runs on windows vista and above. Apart from that, great software. — WritingBadCode

    Yeah, I tend to assume (incorrectly) that most home users have migrated to Windows 7 at this point. — spork
