I was in the process of removing the something that I have got from an Avast download. I found that there is something on my system that is doing massive upload. I run the Avast scan and it find almost 20 infections so I thought that now it is removed. I have used a lot of applications as well as downloaded a number of tools for assurance that the system was spotless. And when I run comodo I notice that a large number of uploading (I will say that large amount of files in cache memory). Then I find that printer stop working it will work under administrator privilege. Could you assist me resolve this? Thank you in advance. I am running windows xp service pack 3.
