Last week I had the opportunity to remove Antivirus System Pro from not one, but two machines. Given that I was seeing it a bit more frequently I thought it might be a new rogue antivirus application, but I quickly found out that it’s been out at least since June of this year. I took notes on my removal so that I could document it here. Just as with most other rogue antivirus applications Antivirus System Pro is a rogue that claims that many things on your computer are infected with viruses (toolbars attached to the browser, most any application you attempt to launch.) It also repeatedly claims that your system is under attack. While web browsing, search result pages are hijacked to redirect to pages of their own choosing and there are occasional porn site popups. (adult.com was one – I suspect the writer has a bit of an affiliate relationship with them?) Read on for how to remove antivirus system pro.
