Hi all, I am having some secuity issues with my laptop. I am running vista, and things just didnt seem right so i ran Microsoft security essentials and it showed a couple of trojans which it now says have been removed. However since then i am getting a Microsoft pop up informing me that the host process for windows service stopped working and was closed and that A problem caused the application to stop working correctly. I then get up a second pop up directing me to Microsoft updates. When i click on the link (or go directly to the Microsoft updates) the page loads but then i get an error saying the connection was reset. My automatic updates is also switched off and when i try to reset this i get a Microsoft window opo up saying the program will not run, the dependency service or group failed to start. As i say im a noob so please explain in idiot proof language, thanks in advance.

im still getting a Microsoft security essentials pop up telling me that i have the following trojan - Trojan:DOS/Alureon.A. What can i do? every time i remove it using the security essentials and reboot it comes right back.

Hi, You might try to run an offline antivirus tool such as Kaspersky Rescue Disk (here). You can burn it to a CD or a USB and boot to it to clear the disk. Hope this helps. CathalCathal O'Brien BSc, PgDip, PhD . Techsmart Computer Repair
