    Hello guys, I'm new on this forum, and I registered because I'm having some troubles lately that I thought I could get fixed in this forum with your help and knowledge, as I believe most of you are specialists in terms of computer.
    (The problems I'll be showing you were mostly seen by my father, so I don't know much details about them...)
    Here's my problem: since last week, my antivirus (Microsoft Security Essentials) was constantly asking me to scan the computer. Normally, it takes about 10 to 20 minutes to do a fast scan, but now it's taking a couple of hours. Besides that, after each time my dad performed a scan this week, the antivirus asks to perform another scan again (as if I hadn't performed before). He told me that when he comes back to the computer (after some hours, doing something else while it is scanning), it has rebooted. The last time we performed a scan was yesterday, and we suddenly got a blue screen of death for the first time. My dad also reported that lately, it's been common to see a window popup, and right after just vanish (a small white squared window appears in the center). Once, he's even seen a box popping up, asking if he wanted to execute some kind of application (by his description, could be the windows safety warning, and of course, he didn't execute).
    If it helps, I've attached the dump file of the BSOD. (apparently, it's a memory corruption...)

    My computer specs are:
    - Windows 7 Professional 64bits
    - Intel Core i7 2600 (non "k" but OC to 4.4GHz)
    - Asus P67 Sabertooth
    - Corsair 8Gb RAM DDR3 1600MHz
    - EVGA nVidia GTX570
    - Hitachi HDS 721010 CLA332 SCSI 1TB

    I would really be grateful if any of you helped me. If there are any other infos you need, just ask me.

    Thanks a lot!

    Welcome to the Malware Removal Forum.

    Please read ALL of this message including the notes before doing anything.

    Pleases follow the instructions in the below link:

    READ & RUN ME FIRST. Malware Removal Guide


    and attach the requested logs when you finish these instructions.
    • **** If something does not run, write down the info to explain to us later but keep on going. ****
    • Do not assume that because one step does not work that they all will not. MGtools will frequently run even when all other tools will not.

    • After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!
    Helpful Notes:

    1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
    2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware and Malwarebytes ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
    3. If you cannot seem to login to an infected user account, try using a different user account (if you have one) in either normal or safe boot mode and running only SUPERAntiSpyware and Malwarebytes while logged into this other user account. Then reboot and see if you can log into the problem user account. If you can then run SUPERAntiSpyware, Malwarebytes, ComboFix and MGtools on the infected account as requested in the instructions.
    4. To avoid additional delay in getting a response, it is strongly advised that after completing the READ & RUN ME you also read this sticky:
    Any additional post is a bump which will add more delay. Once you attach the logs, your thread will be in the work queue and as stated our system works the oldest threads FIRST.

    I appreciate your help, but before making a malware removal, I need to KNOW if there are any malwares...
    Yesterday, I installed another antivirus (Malwarebytes) to see if it would find something. I did a full scan but it found nothng. My unvle says that it's probably a driver problem, that it happens when it's almost full, but mine is at 52GB out of 421GB.

    Not for lack of wanting to be, but unfortunately I am not psychic. Until I see the logs i can NOT let you know if any malware exists or not.

    I really really appreciate your help, but I can't understand what you want to say... (What logs are you talking about, how can I find them, or something else...)
    I'm also sorry if I'm being a little dumb, I'm just not a computer expert at all, I just know a couple of things I researched.

    Sorry. I'm finding it really hard to understand what you find confusing. Have you bothered to read my post #2 or click the links? This is what you have to do, and it gives you instructions on how to run tools, which generate logs for us to review. If you are still struggling is it a possibility a family member/friend/neighbour can help you? :confused

    Oooooh... I thought your links were for malware removal only... I may read them again as soon as I'll have time (too much work on school, now...).
    I've talked to my uncle, who's also a computer expert, and he says he's pretty sure that it's a driver issue, wich I find to be weird, as my driver isn't full at all and is only 1 year old. And again, my antivirus (now Malwarebytes) keeps rebooting my PC and getting a BSOD.
    I may post you the logs when I'll have read your links.
    Thanks a lot, BTW.

    You're welcome. :)

    My point is, I can only help you when and if you attach logs ;)
