I'm using Windows Vista Home Premium x64 SP1. Recently I've noticed that after a few days my memory usage remains kind of high. So far this hasn't caused any ACTUAL problems but, I would love to put a stop to it before it does. Slowly over time these instances of taskeng.exe build up in my process list. Each uses between 1.5MB and 2.0MB of memory.

Virus Scans with NOD32 have turned up nothing.
Spyware scans with Spybod S&D haven't either.

As a temporary workaround I've attempted to disable the task scheduler service, however, I cannot set the service to manual or disabled startup. Even while logged into an administrator account the options are greyed out and there seems to be now way to unlock them.

Some preliminary googling revealed that users of IE7 have similar trouble as a result of the way RSS feeds are synchronized, however, I don't subscribe to any nor do I use IE7.

I consider myself rather tech savvy but, I just don't know where to start with this particular problem. If there is any particular information that might help let me know and I'll be happy to provide it.

I have something like that with Help..., fix is easy,its not a virus,no it have conflicting software..,My problem was:- i install KIS 2009 on ESET AV 3, and when they scan, they conflict and hangs on it, so well you have something like that

Somehow I doubt that there are supposed to be 250+ instances of it in my task manager.

Thanks but, I do not have two security suites installed side by side. I'm currently runing ESET NOD32 for anti-virus and Windows Defender for anti-spyware. Spybot S&D is only used for on-demand scans.

Check the Task Schedule to see what tasks are running?
I'd suspect a program that's corrupted would be causing this (if it's not malware).
