We need to turn off windows update and do a malware scan, what types of antimalware protection are you using and you are running vista? right?
Chewy

No. Try not. Do... or do not. There is no try.

Don't worry about the updates for now, let's try and find out what was causing the conflict?

If this was xp I would ask for a running processes list to give me a clue.

Are there any other problems with the computer like signs of malware?
Chewy

No. Try not. Do... or do not. There is no try.

first I would try the manual update from microsoft, then I would consider turning off defender, it's not very good

are all these versions paid? Kasp is a very good AV product

what you want to watch out for is duplicate resident(loading at bootup) protection

anything from utorrent is highly suspect, the best malware writers in the world seed their evil there, often integrating a backdoor trojan or downloader into an installer

by all means turn on windows firewall, it's not the best but vista's is a lot better than xp's which is better than nothing

are you behind a good hardware nat firewall(a router)?

there are plenty of free or very economical protection products, don't resort to cracked ones

:huh:
