I have been using Avast anti-virus for about 6 years and have not had a single virus.
The key to not getting infected is:
1. Avoid suspect websites
2. Avoid torrents
3. Be vigilant by making sure your AV software is ALWAYS up-to-date
4. Never open an email attachment unless you specifically know the person sending it to you, and avoid opening attachments that the user has sent to
multiple people regarding jokes, cool videos, power point, and other multimedia files
5. Employ a good Antivirus, Anti-Malware, and a SECOND Anti-malware in Manual Mode. (I use Avast in combo with Malwarebytes Anti-malware) and I use
Spybot in Manual mode to scan my PC's daily.
6. Use Chrome instead of IE -- it is faster and cleaner
7. I use CCleaner AND Tune-up.
8. NEVER click a dialog box that pops up that you have no idea what it is from, especially telling you that it is time to do something, unless you
know the software that produced it. Most Viruses occur because the user is TRICKED into clicking "OK" or "YES" on a dialog box out of nowhere.
9. Every so often, run your antivirus software from a boot disc, to scan your PC from a low level perspective. All major Anti-virus packages come
with the ability to do a "boot time" scan.
10. Ditto on the Anti-Malware software -- to a boot scan when ever you can.
I manage hundreds of PC's on my network, and the only time I have gotten infected has been from a user being tricked into clicking an anonymous dialog
If your PC is sitting behind a router, I don't bother with the firewall features of windows or any other programs. But NEVER plug your PC directly to
the net through your cable modem. Buy a Linksys router and have that dual protection in place -- Your cable modem then a router, then your PC. Let
your second router assign your IP's via DHCP, not your primary cable modem.
If you are on a MAC, the best tool I have in my arsenal is Little Snitch which basically allows you to control apps that access your computer from
the net and vice versa.
