A few weeks ago, I downloaded Diamond wormguard to protect my PC as I was having problems getting rid of the viruses. Eventually I got rid of them by deleting checkpoints made by Second Chance. Now I found that I cannot open e.g "hijack this" by double clicking on it, as it is asking me that it needed wgscan.exe to open it. The only way, I could open it, is to right click and then select open. I have found some of the files with a window icon, I cannot open e.g TMP file, GID file and Exp file. I honestly do not know what the extension means and I am hoping somebody will be able to advise me. I am using Windows 98. I have found wgscan in C\PQSC\CPS\000127\NEW\Wormguard in Power Quest Second Chance by doing a search on files and folders. I did not find anything in the registry. It seems to be the problem. I have already uninstalled Diamond Wormguard. I have tried to delete it but got the message that "wgscan.exe is a program if you remove it, you will no longer be able to run this program or edit some documents". Is there anything I could do now as I am a bit concerned to delete it and would like to have some expert advise, please. Thanks.
