My laptop infected by a ton of Trojans and it was stop working suddenly. I have tried to delete those Trojans but I failed. I searched for a PC repairman in Coraopolis, PA and found MDofPC Doctor of Computers. I called their office at 11:00AM and the technician came in to my home at 11:50AM. I was amazed by his fast arrival. He repaired my laptop, delete the Trojans without any problem and installed a new anti virus to prevent the same problem happen in the future. His price was also cheap and he explained everything to me. Very satisfied with his service!
