A slow computer in Lorton usually has a clear cause: too many startup programs, a nearly full drive, old hardware or hidden malware. We test for each one and fix what we find, often in a single visit.
We work at homes near Lorton Station and Mason Neck and at small offices along Route 1. You see the before and after startup times, so the improvement is easy to measure.

Why Lorton relies on us
Before and After Times
We time your startup before and after so you can see the improvement.
Malware Checked
Hidden adware and malware are a common cause of slowdowns, so we scan for them every time.
Tips to Keep It Fast
We show you a few simple habits that keep the computer running well.
Speed Fixes We Use
Adware and malware cleanup
Hidden adware and malware slow computers down. We scan for them and remove what we find.
System cleanup
Windows collects clutter over time. We clean it up and tune the settings for speed.
Faster web browsing
We tidy up Chrome, Edge or Firefox so browsing feels quick again.
Driver and app updates
Outdated drivers and software can slow a computer. We update them to current, stable versions.
Final system check
A final check of the hardware confirms the slowdown was not a sign of a failing part.
Startup cleanup
We turn off programs that launch at startup and slow everything down, keeping the ones you need.
Moving to a solid-state drive
We move your system to a solid-state drive so startup and file opening take seconds.
Adding memory
If your computer runs out of memory, we install more and confirm the improvement.
Speeding up a busy office computer
Office computers that handle invoices, estimates and photos fill up quickly. We clear space, move old files to an external drive or cloud storage and check that the drive itself is healthy, so the computer keeps up during the busiest part of the workday.
