RE:"How in the heck do people get so many viruses? I have never had a single virus on any computer I've owned my entire life. Never even used antivirus software until I wanted to specifically scan a few things I got from suspect sources a little over a year ago, and just haven't taken it off since."
I'm generally pretty cautious but I got about 20 viruses last month. Manily backdoor trojans and a couple of worms. You know, the ones that take over your computer and use it to launch denial of service attacks over the net or steal your passwords and credit card numbers via keystrokes.
Unfortunately, Norton didn't find them until they already were on the computer and in most cases could do nothing when them other than delete. As soon as I deleted them, some would reappear, sometimes new ones. Apparently there was a program running on the computer that was inviting them in and Norton wasn't finding it. I also used a program called "THE CLEANER" from moosoft which found at least one TROJAN that NORTON did not find.
Then I brought in the big guns with a trojan cleaner Called TDS-3. This is the cat's a$$ for finding trojans. It found a couple of programs that were MASKING the trojans that were operating on the computer...there were two programs running that were hiding the other trojans. One was called hiddenrun.exe and the other was hide32.exe. After I removed them I found another trojan that had bee masked and when I removed that everything got cleaned up.
So whats the moral(s) of the story?
1. Don't expect Norton AV or any other AV to find all viruses.
It simply does not. To tell you the truth McAffee is better. At least they knew about the hiddenrun.exe file.
2. Even if you update your defintions that doesn't mean
your safe. Sometimes new viruses take months before Norton etc. add them to the defititions.
3. Statements like "I haven't run an AV on my computer for years and I've never had a virus" are just plain ludicrous. How in the world would you know your not infected if you've never run an AV?
4. Even if you run an AV like Norton you need to run a trojan cleaner like "TDS-3" or "the cleaner". I also recommend WORMGUARD by the same company that makes "TDS-3".
How do you protect your computer?
1. BUY A ROUTER! It's a natural firewall (incoming)
2. Run a software firewall like ZONE alarm. WHy do you need both? Because Zone Alarm will tell you what's OUTGOING and phoning home or sending out info on you.
3. RUN an updated AV in the background.
4. Run a TrojanCleaner just in case, or just once in a while. WormGuard is great too.
5. Run Spybot or Adaware pro to keep your computer clean. You can also block spyware with those programs.
Overkill? Not really. Just run ZoneAlarm without a router and see all the probing of your computer that's going on and see whos actually phoning home off your computer.
Get a trace program like VisualRoute or Neotrace and trace some of these probes on your computer. You'll be shocked. Iran, China, Korea, Angola, Zaire...
