My family has a home-based network with approximately 10-15 PC's & devices. We have Comcast Business Class cable internet & ATT DSL as a backup. I am constantly having to clean all of the other PC's in the house for viruses and Trojans, etc. I have suspected that my PC was also infected, however I have scanned using all the major virus scanners and I have not found a single infected file. However, I have experienced multiple issues with my PC including long lag times, screen freeze-ups, odd programs that are not being used (i.e. paintnet, etc) accessing the internet, lots of strange TCP/IP activity & most recently a DNS server linked to Japan. I am running a modest machine wi/ 32 bit Win Vista, quad-core w/ 4 GB ram. I do occasionally use a proxy server but I was not using one at the time that the Japanese DNS server was linked. I would appreciate your help to ensure that my PC is not infected and is running as it should. It has been awhile since I have been on the boards, so please forgive me I have omitted some pertinent information.
Thank you in advance,
