Being a clinical psychiatrist I have a moral and legal obligation to keep my pc 100% clean from all virus/spyware/malware.
I tested every free and purchase antivirus system known. An I found only one that actually works 100%. Never had a virus or spyware in my system in nine years.
Go to, www.filseclab.com and download thier Twister AntiTrojan Virus program. (You will have to pay a small one time fee). You will never have to pay an annual fee for updates, support or new versions. The one time fee is for life. ($29.99)
The software company is located in Beijing, China. They have excellent support, frequent large signature updates an as always all new versions are free. No annual fee for anything.
Comes with a real time scanner that really works. Actually I am quite amazed over the nine years how well it works.
Scans memory on startup.
Real time scanning in the background.
Open any webpage with an embedded trojan/spyware or malware and scanner will clean on the spot. An It is really removed from your system.
Download any kind of program from zips, all compressed files, software files, music, etc,etc, an if there is a hidden embedded trojan,spyware,malware, this program will stop the download and clean. An will advise you to end the download.
Will even find a virus in the installer wizard, like "Wise Installer". And will stop the installation while it is being installed and clean. Plus this program always will trace back who installed the trojan.
I had a trojan in and wizard installer. Twister caught the trojan and stopped the installation. I wrote the origianl company and told them the wizard installer had an embedded trojan to steal your data. The company now uses thier own installer.
You can't beat this software for a one time purchase fee only. Actually I don't know of any antivirus progam that even comes close to this state of the art technology.
All I can say it is worth the one time fee. Your pc cost alot of money and you don't want it destroyed. Plus your privacy is protected at all times.
There is nothing in it for me to praise this program. I tell it like it is. If it is garbage then I will say so.
Make sure that your Microsoft critical updates are updated every second Tuesday of the month when they come out. Keep the current.
Make sure that you have a good firewall. If not use www.zonealarm.com -They have an excellent free firewall and you can all new versions for free.
Download from www.lavasoft.com their Ad-Aware Personal Se excellent program that has been around long before any software company came out with software against adware/malware.
Plus security or no security you need to take care not to enter into sites like Bit Torrent, P2P, (share file sites), porno sites, or crack houses where for sure you are going to be infected.
If you want to spend a little money, use what I use and the Goverment of China uses for an antivirus system. (Only run one antivirus system, in your pc). You can run more the one spyware without conflict.
The link is listed above for the China antivirus program.
Good luck,
