Ad pop-ups generally don't come under malware heading.
Have you recently installed a toolbar to supposedly improve your browsing experience/search performance etc. etc. ?
I find nothing on a domain search for iltili.com so is that address correct ?
Thanks for responding, David.
I guess I misnamed it, it's being referred to as a virus when I did the lookup again, and I'm surprised that you didn't find it...that address is what pops-up in the new window, iltili.com, plus when you Google it there are all kinds of links re: how to get rid of it, but it appears that the ones I clicked on were selling their services, hence why I came to the Avast forum, since that is what I use for my PC.
And probably yes, on the toolbars. Although I do not accept new toolbars when offered in any downloads, sometimes they do seem to appear anyways, and I just recently downloaded 2 games, so that might explain it.
Do you think if I did a new scan for viruses, this one might be detected? By what I've read, it appears that this iltili virus is hard for virus protection programs to detect by the way it hides itself??? Sorry I'm not more learned on computer speak, or maybe I could express myself better so that you might understand...

Thanks.
