VNC intrusion method

VNC installs on your PC along with free software. This method is called "bundled installation". Freeware offers you to install additional module (VNC). Then if you fail to decline the offer it starts hidden installation. VNC copies its file(s) to your hard disk. Its typical file name is vnsystask.exe. Sometimes it creates new startup key with name VNC and value vnsystask.exe. You can also find it in your processes list with name vnsystask.exe or VNC. Also, it can create folder with name VNC under C:\Program Files\ or C:\ProgramData. After installation VNC starts displaying ads, pop-ups, banners on your PC or in browsers. It is recommended to remove VNC immediately.
