I saw this link
formatting link
this newsgroup. But I am still confused. The zonealarm FAQ link is not working. What was suggested is not working with my IE 6.0.28. I am running W2k Prof with SP4. And have a RAM of 512M so cannot understand the issues discussed in the link that it may happen due to less RAM.Is a Trojan masquerading as Windows Explorer or I have some other problem. I have Mcafee ver 8 Beta running and a complete scan does not reveal any problems nor can I find any suspicious programs in regsitry start up or task manager.
Thanks for your help.
