If you have wondered why antivirus programs won’t remove or block spyware, it is simply because spyware is not a virus. Spyware relies on the fact that every time we install new software we click on I Agree to the licenses without reading them. So we voluntarily open the gates to spyware. It looks like we agreed to have the spyware on our system, which makes it tough for antivirus companies to flag these tricky spyware. The only way to remove spyware is with anti spyware removal tools, manually or automatically, through a tested antispyware software program sold by a reputed company.
