Windows XP gives me cryptographic service error and won't let me install the msblast.exe patch. and my company's computer has the virus. What should I do? I used the same patch on my computer and my friends without any problems.

man..i have the same problem...i keep getting that error message...let me know if you find a solution and ill do the same for you..thanks

If you are talking about a single computer, why don't you just remove it manually? It will take you 10 minutes, and your AV updated index will protect you from future infections.

I posted on this several days ago. If you're getting the Cryptographic error in (update.inf) it's normally because the worm has corrupted your Catroot2 directory. Go to \Windows\System32 and rename the Catroot2 folder something like Catroot2old Then go and run the patch. All should be well. -=Bryan=-

I found an answer from someone online and this worked. 1. Goto start, run, and type command. In command prompt type: stop cryptsvc Close out of command prompt. 2. Show hidden files - goto my computer and click tools at the menu bar, scroll down to folder options and open it. Click on the view tab and click on show hidden files and folder radial button. 3.Go to your windows drive (eg, c:\windows) then goto folder system32 and find CatRoot folder, or you can type this in your address bar C:\WINDOWS\systems32\CatRoot and C:\WINDOWS\systems32\CatRoot2 4.Move or Del any files that exist on CatRoot and CatRoot2 5.Then run the patch

k whenever i try to rename the catroot2 folder it just makes a copy of itself so then when i go back into the system32 folder, there is catroot2 and a ctrt2 ( what i renamed it) and the patch wont work because of it. i also tried deleting it. so if anyone could please help id appriciate it.

Here's some instructions I found from the link below. Updates fail to install. In most cases a corrupted CatRoot2 folder causes this. You can fix this by renaming the \Windows\System32\CatRoot2 folder to CatRoot2OLD. Note that you do not want to rename the \Windows\System32\CatRoot folder! Now try again to get the update that failed to install previously. http://www.windows-help.net/WindowsXP/troub-08.html Tufenuf
