We specialize in Virus, Malware, and Adware removal, and the installation of shields to prevent re-infection. We also do wired and wireless networking, solve printer and other connectivity problems, and keep your systems running as they should. On desktop machines, we'll troubleshoot and replace power supplies, network, and video cards, etc. Due to the massive number of different laptop PCs, we don't do much with that hardware. Sorry, we don't fix broken screens on PCs or phones, and we don't work on Apple products.
