    We did a sweep and it said that a trojan has attached itself to a run DLL file and has been quarantined but doesn't allow internet acces.

Hi,

To remove the virus infection, kindly download and perform a complete scan with a virus removal tool.

(Since you cannot access the internet from your computer, you will have to download the virus removal software using another computer which has an internet connection. Then copy the software to a disk or USB drive and install it in your computer.)

You can download the free version of Malwarebytes Anti-Malware from: http://www.malwarebytes.org/mbam.php

After installing the program, kindly perform a full scan with the program.

Please note that in some cases, the critical operating system files may be damaged or corrupted due to virus infection and so in such cases one has to re-install the operating system.

Hope this solves your problem. Thanks for using FixYa.

    Many thanks for the reply.



    It seems that the operating system files are damaged due to the virus so you will have to re-install the OS.



    Before that you can try and install Firefox web browser. Download Firefox from: http://www.mozilla.com/en-US/ (Download using another computer connected to internet and install it in your desktop PC).



    If you can access the internet using Firefox browser, then we can conclude that only the files needed to run Internet Explorer are corrupted and so we can try and re-install it without installing the operating system.



    Thanks again.

Screen showing setup is starting services and want do anything else


When your computer won't boot past the title screen or start-up screen, it usually means you have software problems or a virus.
Almost all Acer computers come preinstalled with a Windows operating system, which allows you to troubleshoot the operating system before locking up during the start-up screen.
Whether your problem is hardware or software-related, this technique allows you to access your desktop to retrieve all the items you want from your hard drive before completely reinstalling your operating system.

Click the power button. Within the first 10 seconds, a BIOS keystroke should pop up.
The keystroke to access the BIOS is usually the "ESC"+"SHIFT" keys.
"F8" is also an option for getting to the BIOS.
After keying the keystrokes, the BIOS screen is displayed.
Navigate through the BIOS system, which is the first system that your computer accesses.
The BIOS contains several commands and options to scroll through to modify various ways to start up your computer or reinstall the entire system.
It contains the booting options of your computer.

Navigate to the desired option with the arrow keys and select "Start in Safe Mode."
Safe mode is an operation your computer can run in which it doesn't use full capacity of your computer's hardware or software, but allows you to navigate to your computer's desktop and hard drive, regardless of an existing virus.
Restart your computer in Safe Mode and wait for it to boot.
After navigating to your desktop, begin dragging and dropping any information you want to save onto an external hard drive or USB thumb drive before the virus corrupts the files.

It may be the device you are trying to connect. shut down everything, unplug , remove batteries, plug in the ISP model, allow the self test, plug in the wireless device, allow it to self test, plug in, reboot the device, laptop, desktop, ipad, phone, whatever. You say you can connect using a Ethernet Cable? Just no connection wirelessly?

My computor wont let me open internetexplorer it show error please send to microsoft i beleive it has some kind of virus that is blocking me access ?


hi,
it's possible that this might be the result of a virus attack in which case you should run a full anti virus scan on your system. However, there's also the possibility of a missing configuration file from the internet explorer setup. I suggest you uninstall the internet explorer and then download a new current version. Hope this helps
