Free Antivirus Software
Important note: Geeks to Go highly recommends uninstalling any other antivirus software BEFORE installing another antivirus application. Antivirus programs often conflict and can cause system slowdowns, crashes, or even leave you unprotected. Here are some uninstall programs that you can download directly from the publisher's website: Symantec (Norton) | McAfee | Trend Micro
- Microsoft Security Essentials: - Recommended!
Click Here for Microsoft Security Essentials
Microsoft Security Essentials is 100% free. Free download, free updates, and advertising free. There isn't even a paid option available. Don't let the price fool you, it's a great offering. Based on their former OneCare Antivirus, and utilizing a unified detection database shared with their Forefront enterprise security product, it's feature complete, with great definitions. Above all, it uses fewer system resources than any other antivirus tested (free or paid). Simple to install, easy to use, runs silently in the background. Compatible with Windows XP 32-bit, Windows Vista/Windows 7 32-bit or 64-bit. Many languages offered.
Your PC must run genuine Windows to install Microsoft Security Essentials Learn more about genuine.

- Anti-Vir:
Click Here for Anti-Vir
Anti-Vir has a clean and pleasant interface. It has a small footprint and is easy on system resources. Based on active infections in our malware removal forum, it's definitions are among the best. It is also more effective against rootkits than most. However, this free product aggressively promotes the paid version. A pop-up displayed after ever definition update (shown below) is sometimes confused as an unwanted popup. Compatible with Windows XP/Vista/7, including 64-bit and Linux.
This free AntiVir® Personal Edition is intended exclusively for private use on a single workstation. You may copy the complete program package and pass it on to others for private use only. The free AntiVir® Personal Edition may not be used for commercial or professional purposes.

- Avast! Antivirus:
Click Here for Avast
Avast is light on system resources, and it's unobtrusive. For the most part it runs silently in the background. It's the only free antivirus with boot scan options. Definitions based on our experience are just average.
While still one of our favorite free antivirus, previous versions only required email registration. The registration must be renewed every year or definition updates will stop, annoying. The latest version received a much needed new interface, unfortunately it also comes with nagging ads to upgrade to the paid version, more annoying. Unless you opt-out, setup will install the Google Chrome browser. Too much annoyance.
Avast could be used only by home users which do NOT use their computer for profit. If you do not meet this condition, you will need to buy a commercial license of Avast. Use it for up to 30 days before being required to register (for free) and you'll be sent a license key via email. Compatible with Windows XP/Vista/7, 32 or 64-bit.

Click here for AVG
The once often recommended AVG is no longer recommended that often on security sites like this. It's become too big, too bloated, consumes too many system resources. It does silly things. Installs the Yahoo Toolbar unless you opt out. Definition updates appear to come from different servers for free versus paid versions, and the free updates have a history of being unavailable too often. Add some embarrassing false positive detections, and below average detection rates. There are simply better free alternatives.
Free Spyware / Malware Detection and Removal
- MalwareBytes Anti-Malware (MBAM) - Recommended!
Click here for MalwareBytes Anti-Malware
The MBAM team is made of up many people who have helped, or still help on forums like this. Their detection database may not be the deepest, but they know which infections you need help removing, and they are good at it. It excels at removing rogue, or fake antivirus programs. The free version has quick scan times, free manual updates, and free removal. Paid version ads active protection, and IP based website blocking.
The popularity of MBAM also sometimes works against it. If MBAM refuses to run it's usually because malware is blocking it. If so, try running exeHelper, or rkill, and then try MBAM again.

- SUPERAntiSpyware
Click here for SUPERAntiSpyware
Despite the rogue sounding name, this boasts one of the best detection and removal engines available. Free manual updates and removal. Makes a great compliment to MBAM. They also offer a portable scanner that doesn't need to be installed, and is great for downloading to a flash drive, or CD from a clean system. Note, the portable scanner is downloaded using a random name to deter blocking.

- Combofix?
Click here for Combofix
You've seen the warnings, don't ignore them. This was never a program designed for the average user. You don't know how to use it, you can't diagnose the logs. Rootkits can interfere with its operation. It can leave your system unbootable. It can delete files you want. You may think your system is clean while it still has active infections. Leave it to the experts. Don't say we didn't warn you.
Free Online Virus Scanners
An online virus scan allows you to scan your system using an antivirus detection database, without having to install the entire application, or uninstall an existing antivirus program. These three have among the best detection rates, and are recommended:
- Eset Online Scanner Uses the very fine ESET detection engine.

- BitDefender Online Scanner Easy to use. High detection rate.

- Kaspersky Online Scanner Easy to use. Excellent detection rate. Cannot disinfect. Slow scanning. Slow updating.

Free Virus Removal Tools for Specific Infections========================================================
Free Firewalls
- Note: Do NOT run more than ONE firewall.
- Comodo Personal Firewall: - Recommended!
Click Here for Comodo Personal Firewall
Easy to use. Nice looking interface. Impressive performance. When you install Comodo Firewall, make sure you uncheck the option to install Comodo AntiVirus.

- Sunbelt Personal Firewall
Click Here for Sunbelt Personal Firewall
A terrific free firewall, but aggressive marketing, and confusing license terms, "Sunbelt Personal Firewall 4 can run in a free mode vs. a full (paid) mode. Install it now, and for the first 30 days it will run in 'full' mode. After that, it shuts down selected features, but will continue to run in 'free' mode'."
