Your AV software pick?

What are y'all using these days for AV real time protection? 

I am using MSE but it's starting to throw off an error in the event log. I've checked it out and MS says to disregard it but I sure hate red events.....

It's just me so there is no network involved and I'm still plodding along with AVG (free) and it's done a good job as far as I know.  It's even getting pretty good ratings these days.  I run Superantispyware now and then and have Adaware but it's been a long time since I've updated or run it.

I checked event viewer and no errors were showing up in my log.

I checked event viewer. No major errors except one about updating...which I think self-corrects itself. Looks like the error happens right after first boot.

The only other errors, mentioned in Randy's links, are from side-by-side and Essent. Which I don't really pay any attention to. (Because as long as I can remember, Win7 has thrown out constant side-by-side and Esent errors.)

Found it. It was related to the AMD video drivers which I hadn't updated for a zillion years. It was either the AMD external event service or a reinstalled of the C++ Redistributable Package, don't know which but it was one or the other. Or maybe both.

It also corrected a DCOM server timeout error as well as a side-by-side error related to MSE so I'm back to a totally clean event log.

That'll last for a day...if I'm lucky.

Ah, spoke too soon, still getting the side by side error:

Activation context generation failed for "c:\program files\microsoft security client\MSESysprep.dll".Error in manifest or policy file "c:\program files\microsoft security client\MSESysprep.dll" on line 10. The element imaging appears as a child of element urn:schemas-microsoft-com:asm.v1^assembly which is not supported by this version of Windows

I've completely removed and reinstalled and it appears that Microsoft has no solution so I'll either try and forget it or use another AV program.

Yep. Get that one every day, but I think it solves itself after updating. I think.

Hmmm.

Do you use Homegroup? 

And get it to work properly with other AV aside from MSE?
