See the bottom for new text. Here's a good reference point from which to start: There's a huge difference between having the dough for a yacht and keeping one file for testing anti- virus programs. Tell me where to go to download the little music program and I'll do it. On-demand scan it with Bit Defender--that's all I'm asking. I'm familiar with HiJack This, but asking people to recognize it by "HJT" is asking a lot. It's not that well known. A few more keystrokes won't kill you or make you look less cool. - Hide quoted text - - Show quoted text - A custom Bart PE disk can make you look like a God. I've become fairly well known at the school I attend (I'm 44 and am attending a trade school in order to change careers). Other students know where to find me (the computer/electronics/telecom/wireless networking lab where I prepped for the A+). Most every week I end up straightening out at least one or two computers. It's good ` experience and I never turn down a chance to try and fix a computer. Most are software issues like virus infections. In fact the huge majority are such. Hardware problems are rare even though many of the owners think that's what's wrong. For example, last week I dealt with a Dell laptop where the display would randomly shut off. At first it appeared to be a hardware issue (the display backlight), but in the end it was malware. I installed Bit Defender from a hard drive in an enclosure (another of my favorite little toys), updated it and ran it. It found 20+ malware programs. After a half-day (4 hours) of cleaning it up the little laptop was working fairly well. - Hide quoted text - - Show quoted text - stiff you. And even then maybe you forgive them. The trick for a virus author is to be clever. Being one of the first to see a new variant is not impossible. FYI, a good but mostly unknown program that can be used as a second line of on-demand defense is A-squared free. It can be configured to where there is basically no trace of it on a box for the most part (manually disable all options and services): http://www.emsisoft.com/en/software/free/ That means it can truly co-exist with other security software without causing any issues. It's another program I use contextually that seems to be an above-average detector. - Hide quoted text - - Show quoted text - Personally, I think you're at a level where Bit Defender with all options unchecked and nothing else would be appropriate. You knew what you were doing when you danced with the little music program. You don't need a program that looks over your shoulder (checks every file you open and every action you take). If you choose to run both, be aware of the services that may conflict. Disable the Bit Defender services until you need/want to use the program. They are: bdss, vsserv, livesrv and xcomm. Further, I suggest trying the Bit Defender / A-Squared combo. To that you can also add Spybot. Every two weeks I manually update and run all three along with a backup of everything critical. Because I have a clue, they never find anything--but I always do it all just the same. Begin the new text here. I've just run into a situation that brought me to the conclusion that Bit Defender isn't particularly special. So, the quoted paragraph above makes me look like an idiot. I have to accept that. See below: Even though I religiously scan all downloaded executables manually and know the difference between safe and risky business online, recently I ended up with an annoying variant of the Trojan Vundo. As far as I can tell, this variant goes by: Vundo.euo which, trust me, isn't widely known. My recommended combo of Bit Defender Free V10 and A2 Free didn't see it coming. And, after the fact, Bit Defender didn't recognize all of the infected files. It found one--but that wasn't enough to stop it. A2 Free didn't see any of it--even at the height of the infection. Here's the deal with this variant: On an XP box it prevents Explorer from running. That means you have no taskbar--no start menu--just the background. Newbies won't know how to deal with that at all. Guys in the know will know to give a three-finger-salute (alt-ctrl-del) to bring up task manger and then manually start another instance (be it crippled) of explorer. From there the box is usable but slow. There is more to explain, but I'll cut to the chase. In my 12 years of experience this was one of the worst infections I've ever had to clear--and it was on my own box! In the end, HJT (Hi-Jack This) was the key. It exposed a key file that when deleted took out the bulk of the infection. From there it was just a mop-up operation (delete orphaned files and registry entries). So, there you have it.
