Every PC user in Vietnam lost nearly 500,000 VND annually

That damage is caused by a virus. According to the Hanoi University of Science and Technology (BKIS) Network Security Center, the proportion of infected computers in the country has decreased but is still high: 93% with more than 16 million PCs are "sticky". 2007 started with more than 300 new malicious code appeared in January.

The summary of BKIS shows that in 2006 it ended with worrisome figures about the computer worm situation in Vietnam: 880 new viruses (average of 2.4 types exposed every day), nearly 4 times higher than the number Data of 2005. " The average damage caused by virus to each user is about 488,000 VND / year, " said Vu Ngoc Son, Head of Virus Department of BKIS, said. " This year has started with an even more alarming number: on average, every day of January has more than 10 worms to appear ."

Last month, 376,000 computers were infected with spyware and adware. Most cases cause access to malicious websites. " It is worth mentioning that when users encounter a problem with spyware, adware, users often choose the solution is to reinstall the computer. This is an inefficient way because in addition to losing time, effort, money to Reinstalling the computer, users can also lose important data because unforeseen errors occur during the installation process , "Son said. " The best solution is to call to consult with experts to save time and effort and do not need to reinstall the computer, avoid risks ".

Flashy continues to be the most contagious virus in Vietnam over the past time. This USB-based distribution program has infected more than 1.1 million computers in Vietnam since its launch. Meanwhile, the virus via Yahoo! Messenger also did not suffer when "crawling" into 195,000 PCs.

Also in the first month of this year, there were 20 VN websites attacked by hackers. These hacks are done in three forms, like the last 350 cases last year.

The first method is direct attack: hackers exploit the vulnerabilities of the website and then control this website. The second way is indirect, bad guys take advantage of vulnerabilities from a website, then find ways to control other sites located on the same server or on neighboring servers. And finally "direct hit" on the domain name, find a way to point the website's domain to another IP address to redirect the user.

" According to our observations, in part due to tight budget, the other part is also due to the attitude of neglect of security, so many agencies and businesses often put their essential websites and servers with websites. Other not important, "Mr. Quang analyzed. " The problem is that hackers may not be able to find vulnerabilities in targeted websites, but they can easily get 'deadly' weaknesses at sites that are less important and less concerned about top security. server. The capture will start from here and then escalate to take control of the entire server . "
