1. Setup Setup has 5 PCs in a Network. Only one PC connects to Internet. Others are simply a part of Network and access internet through Proxy Server. No PC has a right to access local media like CD/Floppy/USB drive etc. Problem If QH had been installed on the Server (Proxy Machine) it should ideally protect the whole setup. But it gets infected often. It seems that QH is not a complete product.
2. Reason Proxy passes packets directly to the Desktops without compiling the file at the server. Thus machines will directly get infected. It needs QH on every machine .
3. Setup have a tight Policy. A UTM device which scans for Virus infection at the Internet and email gateway. No CD/Floppy/USB/Memory card are directly allowed inside the network. QH is installed on one PC and they are scanned over there before sending it to others. So, QH will not be required on the Desktop.
4. Reason No solution is 100%. The gateway solution will be passed say 8-10 times in a year. This can lead to infection internally. Gateway starts detecting the threat say after 6 hours, but it does not know of the infection inside. If Desktop QH is installed, it will detect it even after infection and help in restoring the systems to normal.
5. It is single Machine & gets infected regularly by viruses like Fun love etc. QH is installed on the machine but still I see that the machine gets infected. It seems that QH is not working properly.
6. Reason In most of such cases it is found to be a part of Cable Network or Internet connection with improper sharing on the machine. When it connects to the Internet it becomes the part of the network and hence some machine from the network attempts to infect the computer and QH keeps on blocking it. Solution: Restrict sharing. Patch the Operating System. Turn Off “DISPLAY ALERT MESSAGE”.
7. Issue I know that in my Network there are many machines infected. I have put QH on one machine and it should be protected properly. But, it keeps on giving so many messages and it even hangs up. QH is not able to protect the system properly.
8. Explanation The attack is too severe. With multiple machine trying to attack the system it crosses it’s buffer limits and this can lead to the symptoms reported. A proper sharing rights on this machine can protect the system in such environment.
9. When I am attaching my USB to QH system, QH do not catch any virus. But when I attach same USB into other system, it gives a virus warning. QH is not catching virus.
