Question about Microsoft Windows Vista Ultimate Edition

3 Answers

Vista infected trojan??

I am using an Acer Aspire 5920G with windows vista ultimate. Just recently i got some kind of a trojan virus from a flash disk. Right after my symantec detected it i told it to delete it then i did a system restore. Nothing happened after since and it's been 2 days. Did i do the right thing?
I just noticed that my laptop's overall CPU usage won't go down below 50%, am i really infected by a trojan? If yes then how do i remove it?
Thanks!

    Its iann
    Here's the funny thing, I've been doing a full scan with my Symantec and nothing showed up, and my laptop isn't lagging, in fact its like nothing happened... Do trojans avoid detections?

  • Wiryan Tirtarahardja May 19, 2008

    Its Iann
    the highest process there is only dmw.exe.

  • Wiryan Tirtarahardja May 19, 2008

    its Iann
    dmw.exe around 56,812K. There's like sidebar, firefox, msn with the same usage around 44-57. The rest (around 17-25) is like explorer, eNMTray and such like Acer Framework tray.

    I'm using an ACER aspire 5920G, i had it exactly for a year. Core 2 Duo 2.0GHz, 2GB DDR2 RAM, and an Nvidia GeForce 8600MGT. Its actually pretty standard, no mods.

    The thing is even if Core1 is like on 10% Core2 is gonna work up until like 90% just to maintain a 50% average. I don't know if its suppose to do that even with all the heavy graphics but i'd had a trojan before on my old desktop and i'm feeling suspicious...
    Any effective detection software?


  • Wiryan Tirtarahardja May 19, 2008

    Its iann.
    I scanned my computer earlier (didn't finished it...) using avast virus cleaner and i only found "cannot be scanned" files from Local~Temp files, InstallShield Information files, and system32 winevt logs... Trojan there?


  • Wiryan Tirtarahardja May 19, 2008

    Whew... thanks a lot, I nearly went panic mode...
    I'm gonna check regularly then.
    Thanks again

If your CPU usages is high, check in your task manager which process is using that much CPU.
Please post the process name here.
I probably can tell you whether it is spyware or not...

    How much CPU is used by dwm.exe?
    dwm.exe is known for using much CPU. It's the process that creates the live thumbnails, transparent windows and so on in Aero. If you have several applications active, it will use a lot of memory and CPU to keep track of actual window layout for each application.
    If you have an older computer, this can cause the computer to get slow. If there are other processes which are using much CPU, just post them. You also could post some specifications like processor memory and graphics card.
    Actually I don't think you still have spyware on your computer. To speed up a little you should turn of Aero, which will free up system resources, but you'll also loose some of the nice graphics.

    I've good experience with Ad-Aware from Lavasoft.
    The free version is a full spyware/malware scanner. Paid versions include other features, like live protection.
    You can download it here. Click Download.
    You could get Plus for free, but that's just for a short period. You just need the free version by now.
    You will be redirected to download.com where you can download the file aaw2007.exe. Install it and update before you preform a full scan. It can cost some time, and use much CPU, but it scans very thoroughly.
    Just to free CPU time, you could kill the process dwm.exe...


  • Thx_nb May 19, 2008

    If this program doesn't detect anything, I don't think you still have malware, but I cannot guarantee, of course.

  • Thx_nb May 19, 2008

    No, i'm pretty sure those files don't contain a trojan.
    Just to free up disk space, you could empty your Temp folder.
    From your posts, i think your computer is clean.
    Regular scanning with a good virus scanner, and scanning downloaded files, or files on a cd or flash disk helps keeping your computer clean.
    Also i want to mention that: the fact that a file on a flash disk contains a virus or trojan, doesn't necessarily mean that your computer is infected.

    Good luck with your computer

Okay. trojan's is hard to remove and in most cases restore don't help.

you have a acer so you can use the erecovery tool.
open the program and select set system to default. that will format your harddisk and install the system as then you bought the pc.

so if you have some important doc ex. you must make a copy of them somewhere. if you have a D: drive on your pc you can use that as backup disk.

Hope that helps. in case not ask me.
CS.

A solution to that is to install Windows Vista Ultimate on top of your old vista installation. Just insert your Vista DVD and restart your computer. And simply follow the instructions for the installation.

Hello and thank you for using Fixya!

This issue can occur if your computer is infected with a SubSeven Trojan virus (per, Microsoft).

Run a virus scan and rid of all viruses, malware, etc.

If you have a free antivirus, remove it and install a free trial of Kaspersky. This will rid the virus. You can then uninstall Kasperky and install the free one after removal of trojan.

Hope this helps!

I have acer aspire 5920G, when i instaled windows 7 64bit i instaled drivers for vista 64bit from acer and for the gforce card from the site of the gforce for windows 7 64bit, the problem is that my screen...


the drivers might be clashing with one another. note that if you use windows vista, it comes mostly pre installed with most basic drivers, thus try to uninstall the one from gforce by giong to your control panel-system-device manager-drivers. i am sure you screen will be ok to tell you that its drivers were interfered with.

if this is not the case, please post a comment and i will try to find a best alternative for you problem.

thank you,

Aspeire One can use Vista Ultimate?


Miscrosoft has a Vista tool to determine if your machine can run Vista. I suggest you go one step farther and make sure that all the drivers you need are on their web site and listed as for Vista. DO NOT flash the Bios to make the machine run Vista.

Computer shutting down randomly in the middle of everything...even offline games


This can be the result of a virus infection or an infection of other malicious software such as spyware.

Run a thorough system scan.

If this doesn;t help, tell me and we'll go to the next thing to check/do for this kind of problem.
