I am not a company that does computer repair. Instead, I have on many occasions, picked up computers from friends and coworkers, removed the offending software, and traded the computer back to the original owner for a twelve pack of good dark beer or a big bottle (1.75) of Clan MacGregor. (Yes, I like real cheap rock-gut scotch.) I have found and removed a lot of things, including keyloggers from China, web page redirects, the usual malware, etc. Sometimes it takes awhile since I am not a computer tech by profession. (The chinese key logger took days, since there was a 5 second delay between each keystroke.) I have also helped a few people online and via email in my spare time. ( A recent example: https://www.dfwstangs.net/forums/showthread.php?t=325093
I'm willing to try to help, but with gas prices what they are, it may not be worth it for me to drive to his house for a free twelve pack or bottle of scotch, as I live in South Fort Worth. It may be solveable over the phone, or online, though. What operating system/version is he using? I haven't messed with Vista, yet, so I may not be a lot of help if that is what he is using. How computer literate is he, that is, would solving the problem via email be practical?
My email is m i k e at m i k e w a l s t e d dot c o m if he is interested. Let me know if I can help.
