My preferred tool for support is Teamviewer.  It's a free secure tool that allows me temporary access to your computer so I can remotely assist you with any issues you might have with your computer.  Each connection and disconnection it generates a new random encrypted password.

AVG is one of the top leading companies when it comes to protecting computers from viruses.  Before installing make sure to uninstall any other anti-virus software to avoid conflicts (i.e. McAfee, Nortons, Advast, etc.)  For Malware & Spyware I recommend ADWCleaner and Malwarebytes.

When installing a new printer, scanner, or device, majority of them require drivers to work properly once connected.  If the device didn't come with a disk you can retrieve the software by visiting the manufactures website and navigating to the support section.

One of the common failures with computers is hard drive failure.  That's why I recommend using CrystalDiskInfo Standard.  It can determine if your hard drive is starting to fail and allow you to catch the failure early before you lose your data.

My advice is to run your Anti-Virus, ADWCleaner, and Malwarebytes at lease once a month.  This will ensure your computer is clean from infection and working at optimal performance.

My services are free and if you ever need help or advice with any of your computer problems you can e-mail me.  I can either give you guidance or, using Teamviewer, I can remote in and assist.
