slow/delayed/stuttering pc

    Hello, my computer has been very laggy/delayed/slow for the past few weeks.

    At first I thought it was hardware related but after Avast blocked a bunch of connections and attempted to block registry changes I figured it wasn't my hardware but malware

    problem: very slow laggy computer(I have a gaming computer so it shouldn't be having problems with the things it is) Right click menus take 10-15 seconds to come up, opening programs takes sometimes 5 mins to open. When I do manage to open programs they run normally but are very laggy and stutter often(games are unplayable because of the stutter from 60fps to 0 too often) even as I type this Firefox delays and has to catch up with what I type.

    Problem occurred sort of out of nowhere a few weeks ago, not sure the exact date. I just restarted my computer once and it was laggy/delayed from there on out.

    I ran through all of the steps in the malware removal guide. When I got to the Root-Kit Repeal program that's the first time I saw improvement, my computer ran exactly as it did before it became infected, and then I turned back on my avast shield and it went back to being slow( I'm not if the two are related but it seems to be a reoccurring event)

    The most improvement I saw in computer performance was when I ran MGtools, my computer returned to normal after that, I figured the problem was fixed so I deleted the system restore save points and restarted. After the restart I got a bunch of blocked connections detected by avast and malware, my internet didn't work so I tried repairing, that didn't work so I shut off malwarebytes and I was able to use the internet again, so then I turned back on my avast shield and my computer went back to being slow/delayed.

    Also I should mention that a week ago I had a bunch of registry changes that avast tried to block(you'll see which programs in the logs im sure because I remember seeing them in there). I kept denying the changes but they kept coming so I looked to see what the source was, and the source was from the program so I figured it must have been safe and I allowed. I'm guessing it wasn't but this all happened after my computer had started being slow.

    on the second post I will post a log of the connection's blocked by malwarebytes when I restarted my computer after running MGtools and deleting the system restore points.

    EDIT: just to give some more examples of what is slowed, when I use a media player(VLC) the music will skip and stutter, when I move something onto a flash drive it takes an unusually long time (4hrs for a few 100MB??)

    also when I used to be able to restart my computer and it would fix the problem temporarily(I could atleast play games) the problem would get progressively worse the longer my computer was on and I'd have to restart again. But nowadays I can't even restart it to temporarily play games on it :(.

    sorry for the long read :\

    Welcome to Major Geeks!


    Goto the below link and follow the instructions for running TDSSKiller from Kaspersky
    • Be sure to attach your log from TDSSKiller
    Now also please also download MBRCheck to your desktop.


    See the download links under this icon [​IMG]
    • Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
    • It will show a Black screen with some information that will contain either the below line if no problem is found:
      • Done! Press ENTER to exit...
    • Or you will see more information like below if a problem is found:
      • Found non-standard or infected MBR.
      • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
    • Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
    • MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.
    • Attach this log to your next message. (See: HOW TO: Attach Items To Your Post )

    I've included what you've asked, neither of them found anything.

    Luckily I've found the problem, it was the Avast shields, when I turned them off my computer ran normal. *sigh* I really didn't think it was something so silly like that. It just didn't make any sense to me because I've had the program for about a year+ now and I'm not sure what would cause it to behave like that 3 weeks ago.

    But I still want to be sure my computer is clean, so if you have any further instructions let me know.

    Also what do you think might cause my avast shields to slow my whole system down like that?(it slowed my system but didn't take any CPU 4% at most)

    thanks for you help thus far

    Probably the fact that you skipped or ignore early instructions/warnings in the READ & RUN ME FIRST about having only one antivirus installed. You have AVG ( a resource hog ) and Avast. They are fighting with each other.

    You may have thought you uninstalled AVG but look at your logs. It is installed and it is running.

    Ok, I didn't skip or ignore that part rofl, I legitimately thought it was uninstalled(had a virus a while back that uninstalled all of my programs). The uninstall doesn't work from the program list so I just assumed it was uninstalled. But after checking my program files there's still a folder there for it and a folder in the C Drive for it. It also still has processes running in the background. So thanks for pointing that out.

    I want to get rid of it so I can get a virus protection program to work, but I can't uninstall it from the add/remove(it isn't there). How do you suggest I deal with this, should I just try deleting the two folders manually?(C:\$AVG C:\Program Files\AVG)
