No one likes to use a slow computer, often times a slow computer can be an indicator of a virus. Malicious programs running in the background use all your computer's resources causing it to act slow, sluggish, and unresponsive. Not all viruses are obvious. They can present themselves as advertisements or pop-up programs that won't go away.
Bring your computer in and have it cleaned up. We start by removing the virus itself, then continue the service by checking for other forms of adware which can cause internet issues, registry issues, or slow performance. When you get the computer back it will be running much better than when it entered our shop!
