No. In fact it is the fastest AV engine I have ever installed in my system. But as scan engines aare extremely sensitive to drivers and such, I can not guarantee it wil, work as smoothly in your system.
And since their scores at recent reliaable AV tests are pretty decent, I think you could give this one a try. IMHO it is a very decent AV program, and actually quite cheap (=free). You can get either the free version, or the pro trail which works with just very few naggers- and if you decide to get it, it's rather cheap.
