Diamond CS and anyone considering buying Process Guard, Diamond CS (DSC) may have a great product with Process Guard 3.0 (PG) but my experience does not bare that out to be the case for me. Those considering the purchase of Process Guard might will consider their level of understanding with regard to security in general and the processes that the Windows Operating System (OS) uses and processes used by the applications on their system. Unless your already OS, app & security savy and then unless you are ready for a long learning curve as it relates to PG, you might reconsider that purchase. I only have my experience to serve as your guide and will share it with you now, so you will be able to avoid a mistake I have apparently made. Now I can not knock the service that is touted by DCS to be delivered by PG, but you the user are going to have to have a high level of understanding to be able to set up PG so that it is capable of delivering that service. You are not going to be able to just install PG and go on about your business while it delivers its service to you. You are going to have to set it up to deliver its service to you. If you don’t know what you are doing in setting it up, the protector may become a bigger pain in the behind than what you are trying to avoid with the service it is suppose to deliver to you. I was not having problems with my system before I bought PG. But I bought it. It instructions says that it is best to reinstall the OS and start fresh with PG on the system. Well that was not even an option for me. I would have to be forced to reinstall my system considering the time that would be involved to reinstall the OS, all the apps and set everything back to the way it was before the reinstall. Most likely it would never be the way it was. So to that, the answer was NO, no reinstall. PG would have to go before I would reinstall. That is because PG would then become way too expensive in time for me. I would have to let some of the stuff that it is suppose to save me from to force that reinstall. So with the decision not to reinstall, I installed PG onto my system. Bad mistake! Cause that mistake cost me the time used to make the reinstall that I wanted to avoid. I have only had PG for a little over a week, but that short time has really run the cost of PG up to a great excess, in time lost to the reinstall task (that is not complete yet). And here I am writing this, mounting its cost even higher. After the first install of PG all seemed to be going fine (that was with PG2 only one day). But then PG3 was released, so I uninstalled PG2 and installed PG3. Before I installed PG3. I thought I would uninstall Zone Alarm (ZA), Port Explorer (PE), AOL Instant Messenger, Windows Instant Messenger, as well as other programs used for the Internet. After installing PG3 I reinstalled all of those programs. With PG3 too, all seemed to be ok, ever now and then it would ask me to allow or deny something. I did not have a clue for what an appropriate response would be for those alerts. Sometime I would answer allow and sometimes deny depending on, if I had just taken some action on the computer. But really, I might as well have been flipping a coin to decide, with head giving an allow and tails giving a deny, for what I knew about it. After a while something froze up and I started Task Manager (TM) to close down the problem. But TM would not shut it down. So I thought I would restart the system. I clicked on Restart in the Start Menu and then Restart. The restart box went away but it didn’t start to shut down. I tried several times before giving up and doing a hard power shutdown. I did not know it but I was going into melt down right then. When I pressed the power button to restart the computer it started going through the BIOS info on the screen then all of a sudden the blue screen of death came up. There was to much on the screen to read for the time it was up, but said something to the effect that the computer was being shut down to protect it. The blue screen went away and it started over with its boot. I went into Safe Mode and tried to uninstall PG3. When I finished and rebooted in normal mode it came up. But Internet Explorer (IE) wouldn’t work, but my Instant Messengers would work. My e-mail wouldn’t work. So, I was cut off from making contact with DSC about my problems. I next tried to do a system Restore to a time before the install of PG, but when the system tried to reboot to the restore point, the shut down hung again. To recover I had to do a hard power down again. It was all over then. It kept wanting to boot into Safe Mode. So I thought, guess I am going to have to reinstall my system, cause I can’t use it like this. Then I though I might as well use this problem to my advantage by upgrading my hardware, and get a faster processor than my 1.6 ghz one, since I am going to have to reinstall. I couldn’t get the new motherboard and processor installed for a couple of days. Once the new hardware and OS were reinstalled I thought I would install all the Internet programs with the cable modem disconnected and the main programs I needed before I installed PG. So I did that and put PG in learning mode and then started all the programs I had installed. I reconnected the cable modem and everything seemed great. I even got the confidence to continue with my program installations and all seemed well. Later in the evening I was reading an article on the Internet, when all of a sudden an alert popped up from PG to allow or deny an exe file to run. Since I wasn’t doing anything to cause a program to start running I clicked deny and then another alert popped up and I denied it too. A bit later I shut down the computer to get ready for bed. I was preparing for bed when I remembered something I had forgot to do before shutting down. I turn the power on and it started to boot, but then the blue screen of death came up, and my heart sank, the blue screen disappeared and it started to reboot again. I did not go into Safe Mode, but let it continue to try to load Windows. It got to the first XP splash screen then went blue again and started another reboot. I let it go again, and this time it got past the first splash screen and got to the Welcome screen before the blue screen popped up again. With that one I said enough is enough and then went to Safe Mode and uninstalled PG. I then rebooted and it has been running fine for two days now, without PG installed. I wanted the program or I wouldn’t have bought it. Although, the bottom line is I expect it to work without all this grief I have experienced with its use. If I can get some insight on what I am doing wrong, I might give it one more try if someone can explain how I am to handle those pop-up alerts correctly. But I can tell you all this, I am very, very gun shy with PG now. Any advice I can understand and use for resolving my problems with PG will be greatly appreciated. Here’s hopin’, John Oh, PS: Diamond CS, I have uninstalled McAfee from my computer and hope not to use them again. I would appreciate a referral of the anti-virus program your company uses.
