I used these guys a couple of years ago and they were fantastic. We were having the typical pc problems - corrupted files and/or adware/spyware had slowed our machine down to a crawl, I think we had a few viruses, etc. They came in, cleaned the pc up, switched me over to a better/safer file sharing program that resulted in less problems for their users, etc. Quick, effective and easy to work with. Highly recommend.
