Free Virus Scan Software

Many different antivirus software developers offer free virus scan software that is essential in safeguarding your computer against malicious software such as viruses and adware. To risk leaving your computer unprotected from viruses is not a wise idea, because it only takes one or two to disable your computer completely, or worse, steal your personal data. Some software developers offer a single free virus scan, while others offer an entire security software suite that you can use for either a limited time or indefinitely.

The most basic security features that anyone should put in place are an automated virus scanner and a firewall. Free virus scan software allows you to set the time when the scans will take place, allowing you to set and forget about the virus scanner without worrying about viruses. If the free virus scan software does not include an automatic updater, you need to update the software regularly in order to keep a fresh library of virus signatures.

A firewall is the first line of defense against intrusions on a computer system. It monitors all of the traffic flowing into the computer. If a suspicious file or software tries to pass through the firewall, it will alert you and prevent the file from accessing your computer without your approval.

When on the lookout for virus-scanning software, be wary of fake virus scanners such as Doctor Antivirus or SpySpotter. These are called rogue security software and will often use official-looking logos such as the Microsoft logo in order to trick people into downloading the software. The fake virus scanner may offer a free virus scan that will claim there are viruses on your computer system when there are none. It will then ask you to pay a fee in order to remove the virus. Other fake virus scanners are far more intrusive and will shut down your computer to the point where you cannot activate or use any other software.

In addition to free virus scan software, there are other free security tools available on the internet from a variety of software developers. These include anti-spyware measures, email scanners and even social networking protection. While free virus scanning software offers fewer features than the average professional version, the virus scan is typically just as effective in the free edition as any professional version. However, most professional, paid virus scanners offer heuristic detection, which does not rely solely on a catalog of virus signatures. This allows heuristic virus scans to detect viruses that were previously unknown.

While it is important to be on the lookout for fake antivirus scams, free virus scan software is relatively easy to find on the internet and is essential for protecting computers from the most basic threats. A computer that is unprotected from the threat of malicious software is bound to become inundated and hampered by some form of adware, malware or a virus at some point in time.
