No not 2 resident scanners. I have 1 resident scanner. I know not to have more than one resident scanners. I wasn’t going to use the resident scanner. I was going just use the on demand scanner.

Running 2 AV’s on 1 pc is a bad idea.
Why ?
Because it’s extemely hard to “unload & disable” the complete resident processes from a scanner. They always seem to load something. And could give problems on low-level system.
Use a online scanner as backup from time to time. They work just as good as the “full” version. And don’t need to install much, only some virus definitions and some active-x
files.

The only backup scanner that is known to be without problems is the freeware scanner from Bitdefender v7. Wich doesn’t include resident scanning at all. It offers a good detection rate.

I used to have Nod32 as a resident scanner and Avast4 as a backup one…
if you check this thread ,you will find that an AV like Nod32 loads a vxd file before loading witnodws and it denied access to files for any other AV one the computer (problem solved by Vlk ;D )…
So, now I have Avast4 as my main scanner and Nod32 as the backup one…

The problems you had with Nod and Avast together seem to prove my point,
That most of the time, 2 Av’s mess-up each other.
Offcourse, it can be fixed (like you did btw) but it needs some serious tweaking & knowledge to do it.
Glad to see your system is running good now Minacross.
Kind regards,
