I have recently installed the Windows 7 operating system on my computer. Earlier it was running Windows XP. Currently, it does not have any antivirus installed in it and I was thinking to install the Quick Heal 2011 pro. I downloaded the Quick Heal 2011 pro installer from net and tried to install that on my computer. I followed the onscreen instructions properly and I am sure that I did nothing wrong with the setup. When it comes to the step where it shows "Scanning Memory", I found that it closes directly without showing me any notification or something. After the first step of installation, I also lost my internet connection. In short, installation failed. I tried to do the installation two more times but both the times it comes up with the same result. Now I am helpless and looking for some suggestion from the people over here. Please help me friends.
