What exactly is this?

What? I don't get it.

ah i get that don't download i did and got viruses on my comp

but i get it as a pop-up its really annoying

lol, so why does it pop up at random when I'm browsing the web?

Dunno my comp's randomly been allowing pop-ups, its annoying, its also been finding illegal stuff to apparently   dont know where that came from though 

WinFixer, WinAntiVirus, ErrorSafe, SystemDoctor and DriveCleaner are identical or similar computer programs available for Microsoft Windows that claim to repair computer system problems. They are forcibly installed on the victim's computer by the SysProtect vector. They display false information with regards to a user's computer, thereby confusing said user into believing their PC is infected with viruses, spyware and/or other forms of malware. The adverts pop up a display with notifications to convince the user that something may be amiss with the computer, or run a fake diagnostic. The program repeatedly prompts the user to purchase a licensed copy of the program.

Due to these problems, WinFixer and its sister applications are generally considered scareware spyware. Indeed, their misleading popups and forced downloads mirror the infection strategies of many spyware programs. Computers infected with this trojan also exhibit sluggish performance.

Wow. Those bastards.

When the user chooses any of the options or tries to close this dialog (by clicking 'Ok' or 'Cancel' or by clicking the corner 'X'), it will trigger a pop-up window and WinFixer will download and install itself, regardless of the user’s wishes. Because this is a dialog box related to the Internet Explorer application, it does not appear in the Windows Task Manager list (Ctrl+Alt+Del). However, the user may be able to avoid installing the program either by using the Alt+f4 command or by disconnecting from the internet before closing the dialogue box.

Oh shut, I clicked cancel =x

lol yeah thats what happened to me but if you click X then X again quickly it cancels it,  but it didn't install my anti virus software found it in 5 secs and destroyed it


still my recored is 400 trojens and 100 viruses, so many, destroyed nearly all the programs, i think paint still worked

If Mcafee doesn't pick it up, I'll just have to be lazy and hope it didn't download =o

if your using a firewall and an anti-virus it should be fine firefox or similar also would help to reduce risk

In Firefox there is the NoScript extension.
It should be quite helpful with these matters.
Just remember to allow rmrk.net if you use it
