We opened an email of an old friend, when all of a sudden heard these screeching noises and were unable to do anything with our PC. There was an instruction to contact via telephone to get this fixed. We did this and finally allowed them access. We paid them for this service and what they said was a years maintenance. However, we were never comfortable with allowing this access to an unknown entity under these circumstances and regretted our action and the possibility of being scammed. Through a recommendation on Angies List, we contacted B2B I.T. Actually, the owner immediately came, spent several hours checking and addressing everything questionable on one of our PCs and took our second one back to their office to complete its review and any problem resolution. B2B I.T provided immediate, extremely professional service, explaining everything as they proceeded. We were so impressed that we asked about any maintenance programs they might have and immediately signed up for their best plan and paid for an entire year.
