We have what we think is a serious infection on our computer. Exe files have disappeared so some programs have become useless. On Internet Explorer, when we click on a link, an error message comes up saying the page is not available. We have run Ewido, Ad-Aware, Spy Sweeper and Avast and they were able to catch and delete some viruses but the problems persist.
We need help! Can we post a Hijack this log without running the programs you recommended first?
