Just uninstall all of it and use window defender for crying out loud.
But in reality the "extra" stuff they want you to pay for is generally a "hands free" solution (ie) auto updates or features that other Suppliers already give you for FREE all the time. By using a selection of anti-virus and system care tools you get all the features of AVG paid for versions. Incoming and outgoing access can also be controlled with FREE programmes. Try going to the site at majorgeeks .com and see what you can get for FREE Avira, Bitdefender and Comodo all have malware versions that complement their antivirus's and they are FREE as well
Majorgeeks and other software sites such as Snapfiles will give you the free stuff with limited features. If you want to upgrade to unlock the full program, you have to pay for it. The software companies want you to try their programs so let you have them for free in the hope that you like them so much that you'll pay to unlock all the features....... for example, Malwarebytes is probably the number one anti-malware program out there and you can try their Premium program free for 14 days, after which the extremely useful real-time protection that prevents incoming and outgoing access from your your pc to dodgy sites is removed unless you pay and upgrade......... here, AVG are giving you the FULLY featured program for free!
OR.......you could just go to majorgeeks.com and get FREE antivirus and EVERYTHING else you could need for your PC for FREE as well............FOREVER!! (ninja)
After switching to Bitdefender, which just runs quietly in the background without hassling you with adverts every time you log on (my god Panda was bad for that), I'm not looking back.
