Common computer cure virus

Dream team! Well, you could sign up to the trials. No, thank you. It would be exciting — you never know, you might get the placebo rather than the vaccine. I would happily take nothing in pursuit of science. Oh, another thing about a cold vaccine: could it give lasting protection? Survivors of the flu pandemic were still producing neutralising antibodies 80 years later.

In fact, the data suggests we need a bit to get in — a little poke from the virus — to remind us how to fight it. The computer virus was once public enemy number one in the cybersecurity field. However, hackers have dropped that cyberweapon in favor of other forms of malware in recent years. Tools and tactics such as exploit kits, spear phishing and distributed-denial-of-service attacks have provided cybercriminals with malware that was better equipped to address modern cybersecurity defenses.

Meanwhile, the virus fell behind the times and quickly became an outdated and rarely used resource. With the spread of constant, high-speed network connections, other forms of malware sprang up that could self-propagate at a much quicker rate than the old standby.

Furthermore, hackers have increasingly favored stealth behavior in their malware, allowing programs to lurk within a system, undetected for months and sometimes even years at a time, while relaying data back to the criminal.

Viruses, by their very nature, are incapable of achieving this functionality as they will quickly attempt to infect a large number of files upon breaching a system.

The return of the virus A recent cybersecurity report, however, found that the computer virus has made a comeback in certain parts of the world. While its prevalence remains low in technologically mature markets such as North America and Western Europe, large numbers of viruses have been detected in emerging broadband markets including Central Asia and Africa.

Pakistan currently leads the world in virus rates with 44 percent of its systems reportedly showing signs of infection. Indonesia, Ethiopia, Bangladesh and Somalia round out the top five.

Most bacterial infections can be treated with antibiotics such as penicillin, discovered decades ago.

However, such drugs are useless against viral infections, including influenza, the common cold, and deadly hemorrhagic fevers such as Ebola. In a paper published July 27 in the journal PLoS One , the researchers tested their drug against 15 viruses, and found it was effective against all of them — including rhinoviruses that cause the common cold, H1N1 influenza, a stomach virus, a polio virus, dengue fever and several other types of hemorrhagic fever.

The drug works by targeting a type of RNA produced only in cells that have been infected by viruses. Because the technology is so broad-spectrum, it could potentially also be used to combat outbreaks of new viruses, such as the SARS severe acute respiratory syndrome outbreak, Rider says. Few antivirals available Rider had the idea to try developing a broad-spectrum antiviral therapy about 11 years ago, after inventing CANARY Cellular Analysis and Notification of Antigen Risks and Yields , a biosensor that can rapidly identify pathogens.

There are a handful of drugs that combat specific viruses, such as the protease inhibitors used to control HIV infection, but these are relatively few in number and susceptible to viral resistance.

When viruses infect a cell, they take over its cellular machinery for their own purpose — that is, creating more copies of the virus.
