I used my Acer Aspire 3000 series laptop's Internet Explorer to surf the web last night via wireless link to my home network. After a couple of hours of this, my Panga Titanium 2006 antivirus software displayed a warning about a suspicious file and renamed it "qtzgacer_exe.vir". At that time, Internet Explorer quit working. Changing the name back won't work because Panda merely renames it . Terminating Panda and renaming the file back to "qtzgacer.exe" allows IE to work OK, but without Panda antivirus protection. Not good. It seems that my "qtzgacer.exe" file has been infected. Help!

it provides for the green text on the screen indicating changes in the volume
it uses 100% of CPU = it slows down the computer very....much
It has completely locked up my laptop CPU until I terminated in Sys Manager

my system will freeze occaisionally and QtZgAcer is using 99% of my cpu in task manager. I stop the QtZ... and the computer functions normally. IEexplorer seems to work fine without it. sometimes QtZ... is running without ill effect but something will trigger it into overtime then nothing works til I stop it.
When I turn my Aspire 3000 on and this starts up with the computer (which is about 50-75% of the time) it takes 100% of the processor capacity and makes it so I have to pull the battery to reboot. I'm not sure how to take this off my computer, but I soon as I find out, it's gone. VERY dangerous as it completely takes the computer out of business..
This exe starts when I power my Acer laptop. I have had this computer for a little over a year and never had any problems with this exe file. However, lately I noticed when I login to Windows and see the desktop the computer's CPU gets occupied and this takes several minutes unles I terminate this exe file.
it is a file FROM Acer. I think it has has been a problem since a MS update... It can be disabled...

Its a Tool from Acer but also here it takes 100% CPU Load for minutes, so it seems to be buggy!
it running just 880K and no CPU usage
uses 97-99% cpu. task manager says cpu usage is at 100% all the time. I have webroot paid antivirus with antispyware and have run spybot s&d and malewarebytes antimalware. computer is still slow.
when i start my system, QtZgAcer.EXE takes nearly 98-99% or my cpu capacity making my laptp almost jam for any other operation so ultimately i had to disable it from msconfig start up. My laptop's performance is much much better now
it screwing up my quicklaunch bar

Best practices for resolving QtZgAcer issues

A clean and tidy computer is the key requirement for avoiding problems with QtZgAcer. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
