Thank you DM,I have hard time to get from BC for how to use of combfix but from other web I got it. my problem is my computer freeze every few minutes and no way I can down load any use ful program.For possible regisre problems I all so run norton utility but not help.Do you know any way to release the freeze up instead by cut off the power? My computer use AMD sempron P3200 and has a lot of ram 1.250 GB.Another thing is my computer already has NIS if I down load other anti virus program will it be conflect each other?I check the working histroy of NIS and found out that freeze up alway happen when NIS conteract harmful attack.Should I disable NIS to prevent freeze up.I have last resours that use the restore disk to clean out all in HD.I already back up all my useful file.What should I do?

What I would recommend, is if it is not risky, disable NIS.

Now, you may be able to transfer the download from a clean computer to the infected one, via flash drive or burnt CD/DVD, etc.

Frankly to tell you that DM,I did try use other antivirus program such as microsofe antiviur scan and sypware doctor all failure to complete the scaning due to freeze up and no way to identify what malware they are and where they hide,because this even try use manual methoid and
failure.What other suggestion?For technical point of view I don't want to give up and jump to the last resours.This malware,what ever it is,is very smart and hard to due with.

Hi DM or any one;I watch the tech.support people of norton work on my computer(through remove reach) they scan the computer and freeze up few times but each time they just click and the freeze loose.How can they did it?Any one know?If I know how to do that then I think I could solve the problems.

Sounds like a faulting program. Seems there would be malware trying to freeze the computer often.

Hi DM,I carefully review the histroy of the work of the NIS: most the time freeze up match the time report as;unauthorized access blocked,(send terminate message to window) actor;c:\windows\explore.exe TAGET;\device\harddisk volume\program files\norton internet security\norton internet security\engine\17.5.0.127\mcu32.exe.What this mean? is this attack from inside or from out side? please explant to me.

Remove NIS from your computer and see what happens, please.

NIS unstall result as following;computer run very slow and many program not respone to arrow oders.Window security warning.Arrow freeze from time to time.Freeze again when try to reach web antivirus side.What should I do next?Why these happen please explant?
