Hmmm, i'm supprised ESET slowed it down. its been great on mine. Although I have reinstalled Win7 tonight for other reasons and thought i'd give Kasperskys Latest offering a go

I must admit to preferring it to Eset, I'm just a Kaspersky fan.

Not sure about the error, any eset folders left over in the programs files folder?

I'm a Kaspersky fan aswell. But I am running W7 64 bit and couldn't get my copy of Kaspersky to install. I'll check out the link you provided.
No Eset folders/files left that I can find..Might try reinstall then remove NOD32 and see if that corrects it.

Problem solved. Show all hidden folders and there was one ESET folder lurking about, so it was deleted. Suppried the ESET removal tool didn't remove that....mmmm

Kaspersky 2010 works well in W7, I'm using it at the moment myself - in fact there should be a review up soon.

The initial ESET problem might have been down to a plugin that it uses for e-mail scanning, I've had this a few times with AV suites. Loading Outlook in safe mode then disabling each addin often isolates the problen.

Ah so 2010 does work? Nice.

That 6.0 i posted above is near identical to 2010, but i'd have installed that had i known it was good. (i read somewhere that the new KIS dont work, oh well obviously they do, lol)

Actually there's 1 small feature in KIS 2010 that doesn't work with Windows 7 yet - the "safe run" feature, but all the rest works great. IIRC, I think you can do an in place upgrade easily enough from V6 > 2010

Ah well i'm gonna give it a go then, 2010 is very good. Think the RAM usage is a little lower than 6.0 too, which is nice.

Now back running 2010 with my old licence key. I had 88 days left so i may aswell use them.

Eset did start fractionally faster, ill give it that, my desktop gadgets take a few seconds more to appear with KIS. No biggie though.
