strange new virus
« on: July 18, 2009, 06:22:38 PM »
I've encountered a strange new virus on my work computer, home computer, and my girlfriend's computer.  While surfing the internet, suddenly a screen will come up telling me "Warning, visiting this site may harm your computer" then you have the option to click "continue unprotected or get security software".  Without thinking, I clicked the X to close the dialogue box.  Upon doing this, I could not go to any website whatsoever.  Every site would say I am not protected.  Just FYI, on my work computer I'm running a corporate edition of AVG.  I also us Lavasoft.  Initially, AVG was not able to detect anything.  I tried restarting the computer, disk defrag, disk cleanup, and several other standard procedures.  None of this worked so I finally did a system restore to 2 months previous.  This worked for about 2 weeks and suddenly the same thing happened again.  This time, when the message popped up I used control alt delete to close everything without clicking.  I ran all virus scans out of precaution and have not had a problem since then.  

That is, until a few weeks ago the same sh&* showed up on my home computer.  I did the same thing, control alt delete and run all virus scans.  Apparently successful once again.  However, now my girlfriend has the same thing on her computer only she mistakenly chose the option to continue unprotected and she can now no longer go to any website.  I'm at work and have not gotten a chance to try and fix it for her.  What I'm really wanting to know is how this thing is able to install itself so easily.  Nothing malicious was ever downloaded on any of these computers.  Anyone have any ideas?

As far as the work computer goes, you need to contact the Help Desk where you are employed.  Let's do the other two computers one at a time.  Otherwise, it would get confusing as to which machine we're helping with. 

In response to your question, particularly if a computer does not have all security updates, up-to-date antivirus software and software firewall, it can be infected by a drive-by install.  See Rogue Antivirus - A Closer Look at Win32/Antivirusxp for an example of a drive-by.
