Avira offers a "FREE" virus protection download. BUT, , , they try again and again to have you buy an "upgrade" to a paid product.
IF you do not buy upgrade, they launch a virus ad/spyware into your computer to shut down all functioning.
The only cure is to "UNINSTALL" Avira, get a legitimate virus protection and find and kill the virus files and cookies of spyware that Avira has put in your machine.
All in all, a very damaging and frustrating waste of time.
Avira refuses to respond to ANY of my complaints about their horrible product and virus files.
The virus file they slip into your machine is; ADSPY/FalseInstaller
and it comes in many (13) elements and cookies.
AVOID THIS HORRIBLE COMPANY AT ALL COSTS !!!
