Vundo, Generic.dx, Downloader_BFC – next generation viruses

.

I have been testing all kinds of antiviruses to see which one is more reliable. On my sister's laptop, I have kaspersky. On my personal laptop, I have NOD32 and on our home computer had MCAFEE .

Around 2 weeks ago, the internet explorer on my home computer started crashing more often. I get random pop-ups every few hours despite the fact that pop-up blocker is installed. First thing I did is to do a system scan with the Mcafee. Didn't detect anything. I forgot that it is unlike kaspersky and NOD32 where you have to update MCAFEE manually. So after I did that, I kept getting virus alerts about the existence of random viruses such as "vundo", "generic.dx" or "downloader-bfc". What was even more annoying is that none of them can be cleaned. It would start with a pop up screen saying that a certain file is infected and showing the path for it. But then when you go to investigate the path, the file is no longer there.

Apparently, the viruses work by generating files in C:\windows, C:\windows\system32 and in C:\program files\common files and all paths that you wouldn't wanna miss with. What's even worse is that it'll create random .dll & .exe files that leaves you guessing on whether these are system files windows need or not.

That's why googling a solution was not really helpful as each case is computer specific. The files infected at your pc would differ than the ones infected at mine. And that's why all those guys who are infected ended up consulting an online technician who'd provide you with tools to use and we'll request you to post back a log file of the scan results. Accordingly, he'll study the log files and will manually be able to nitpick the path files you need to remove.

After I gave up on removing the viruses by myself (which I find it very humiliating as I come from a computer science background and I pretty much consider myself a techy person), without the need of formatting my pc, I went for my last option of creating an account on forums.techguy.org and asked for help. More on my experience with those viruses can be found here.

I'd like to thank racenutalways for his patience and for helping me to get rid of these annoying viruses. From all this, I learnt my major lesson. I uninstalled MCAFEE and now I am using AVG antivirus which is much faster and much more efficient.

The last 2 weeks left me in awe for those virus writers who got so creative that created viruses that create such random, computer-specific files making a universal removal tool almost possible.
