You may have noticed one or more commercials on TV that claims that they can remotely connect to your computer and make it "work", however be sure they don't charge you if they can't. Most problems today are spyware and virus related and there is absolutely no way this can be cleaned remotely, even if your Internet is working. If your system is just bogged down from normal use, be sure you pay no more than you could at a local shop for a service that is hyped late night alongside the vacuum cleaners, kitchen gizmos, and colon cleansers.
Today's viruses can only be gotten rid of one of two ways. Reload your computer to factory default (fresh load on built PCs) or to have a professional clean it. Badware starts before nearly any other software including antivirus software and only by booting up on an alternative operating system and scanning, cleaning, and repairing can you rid a PC of the bad stuff. With 1,000,000 viruses found each day and growing, it takes know how along with the tools to properly clean a system and you can not do this remotely from Arizona unless you created the virus and know the back door to get past your infection to then clean it up.
Update: It has become apparent that most of these companies doing business under several different names are fronts for Cyber Defender software. Based on our experience Cyber Defender is crap! You might as well take an asprin for cancer, it just that good in comparison.

Just remember that if "his" computer works, its because its sitting right in front of the technician that fixed it, not that it was fixed over the phone or by remote control.
