I have had an ongoing problem with not being able to open attachments on E-mails which I receive. I allowed the self diagnossis to recomend a fix. The recomended fix was Regwork, which scanned free, then wanted to sell their service in order to fix the over 400 problems which were discovered. I read one review site, which appeared to be negative reviews according to the title, but when I read the comments they all seemed to be good. I should have suspected that it was a site which THEY had set up themselves. Anyway, I paid for their 2 year service and ran the program. It did nothing to solve problem, and also erased programs which I use regularly. It also erased the memory of my system restore, so I can only restore to the time AFTER their program was run.
