right after start up I get the message: windows explorer has encountered an error and needs to close. more info: AppName: explorer.exe AppVer: 6.0.2900.2649 ModName: fcyaxww.dll ModVer: 0.0.0.0 Offset: 00001c6f. Any Ideas on how to fix this error?

It appears you may be infected with malware. Run Adaware 2007 and Spybot Search & Destroy 1.4.

if spyware softwers wont help. try upgrading your explorer verison with windows update.

itaioh This is "Windows Explorer" not "Internet Explorer". There are no specific updates to a later Windows Explorer. From a security standpoint it is always sensible to have the latest updates for everything but doing this now will not fix malware or viruses if they are "already on the system". DerekW

Scanned with updated version of spybot v1.4 found a firewall disable and an antivirus disable. scanned with pc tools spyware doctor and found trojan downloader.con hook and trojan popupper. both were removed. scanned with vundo fix nothing found. Ad aware 2007 found found two critical items windows registry item HKu s-1-5-21 and broadcast ipc data miner both of witch were removed

Thankds for posting back, utlucky.

Err...perhaps it is obvious/implied but are you saying the problem is now fixed? If it is definitely fixed and you are now booting OK you should delete your system resore points and then make a new one. Otherwise this trojan will come straight back if you should need to restore the system and it happens to have been present in the original save. DerekW
