to install or launch application or setup files.
I suggest to use a clean PC to download Rkill or exehelper to hopefully bypass the malicious processes. Transfer it to the affected computer:
Run rkill.exe in normal and allow it to do its job by stopping and ending the task of any found malware process.
Do not reboot when rkill is finished with its task. If rkill.exe will not run, proceed in trying another file format (e.g. rkill.com or .scr or .pif or use exehelper).
If an antivirus is installed already, immediately try opening it then update soon. Scan the system.
If antivirus is not installed, get or use any of these after using rkill or exehelper:
Install, update then scan Malwarebytes or SuperAntispyware or immediately open the browser to use MalAware scanner.
Okay, so this is some background info.. I'm trying to fix my friend's laptop. The problem was originally with the internet, it would stop working every few minutes which got in the way of games and other things. Neither of us really noticed until yesterday when he tried logging in to a game site and it didn't log him in. I figured it might be because he's using an outdated browser (earlier version of chrome), but it wouldn't be the first time this computer didn't work right. SO, it compelled me to go download an antivirus, which I thought would fix some of the lag and problems. I tried to download avast, got a error page. I downloaded the avast installer on another comp, renamed it, then put it on the laptop and tried again. The installer froze multiple times, and when it actually installed the main program didn't open. I tried downloading MBAM, clicked the installer and got an error. Tried downloading anything I could find, and when I tried opening I got an error. so basically, virus isn't letting me use any AV programs.. and anything I download isn't working either... I would try a factory reset, but thats not on acer comps... some of the errors dialogs http://i49.tinypic.com/ae8bia.png (obviously fake) -- any help?
