I guess this is the sort of thing which would be obsolete the day it was posted, but is there a list somewhere of secure websites--those from which you can be confident that you won't get any viruses? I am already to the point where I never open an email attachment, and usually only access websites I consider to be reasonably secure, with my own computers.
Good question. The only problem is there are two answers: yes and no.
At this stage of development, it is virtually impossible for any Website to install code on a computer unless the user cooperates by approving a download, or clicking an advertisement. If you accept a download which purports to make the site "better" in some way or other, then you're at risk. Some of the typical ploys are offering plug-ins which allow display in another language, allow animations to run, or offer "free" scans for malware. Not all of those are malicious; however, enough of them are to cause me to recommend that you never accept them. To quote the venerable Nancy Reagan, "Just say no."
Viruses, Trojans, worms, and keyloggers are the truly bad boys of the Internet. They're the ones that can harm you or your computer. About the only way to combat them is to install a recognized antivirus program, then keep the definitions updated at least once a week, but preferably every day. Configure the program to run continuously in the background, and to perform a boot-virus scan when you turn on your machine. Daily, full-system scans may be overkill, but by scheduling them for a time when you're away from the computer they shouldn't interfere with your usage all that much.
A good firewall (and there are free ones) will prevent Trojans and keyloggers from accessing the Internet, whether to spread themselves or to send your personal information to some asshole. Configure your firewall to automatically check for updates, and set it up to run continuously in the background, even if you're using a dial-up connection. In addition, use free programs like Ewido, Spyware Doctor, or McAfee's Stinger (all have free versions) to ferret out and remove this stuff.
Other types of malware, such as spyware and adware, usually won't harm your computer. However, they can make it run more slowly, and I'm sure all of us would agree that the constant stream of pop-ups caused by some adware is maddening. To combat this type of crap, use programs like Spybot Search & Destroy, SpySweeper, or Lavasoft's Ad-Aware. Run on a weekly basis, these programs will keep your computer reasonably free of garbage.
All of this may make it seem as if the Internet is nothing but a cesspool, full of shit just waiting to infest our computers and destroy them. While bad stuff can happen to those who aren't proactively engaged in protecting ourselves, those who are can have enjoyable, safe experiences, as they surf for hours on end. I've used the Internet since 1994, and in all that time have never had a single virus, Trojan, worm, or keylogger on any of my computers. That's not to say it will never happen, but so far it hasn't, because I practice "safe surf." You should do the same.
Probably the most-important single thing you can do to protect your computer is to get a disk-imaging program and use it. Believe me, there's nothing in the world as satisfying as having that sort of protection in your desk drawer when your computer crashes and can't be revived. That simple precaution can save untold hours of frustration, and several hundred dollars of unnecessary expense when (not if) the time comes when you have to reformat and re-install your operating system. I know that for sure, because I've done it several times on my own computers, as well as those of many of my customers.
