Malware Infections Decline, but Trojans Remain Dominant
According to Security Company Panda Security, which has just announced the publication of its yearly paper on Internet security, 39% of PCs on which a scan was run during February 2011 had some form of malware infection or another as against 50% during January 2011.
States the paper, Trojan viruses had been the most-widespread among security threats, accounting for 61% of the entire malicious programs. These were followed with viruses (11.59%) and worms (9%) among the total malware globally.
Also, during February 2011, Trojans were responsible for six among the ten most-widespread malicious programs and the paper substantiates that Trojan.Win32.GenericIBT was the top malware whose detections grew to 22.97% since January 2011.
Moreover, soon as these Trojans, which connect to bogus security software, infect end-users' computers, they start scanning the PCs as also give fake alerts in order that the users become convinced and purchase the bogus security programs.
Said Senior Threat Researcher Chris Boyd at GFI Labs, the above kinds of assaults caused immense trouble for those attacked alongside just contaminating their PCs. Help Net Security published this on March 4, 2011.
Furthermore, Panda determined that 4 countries, which were the greatest sufferers of infection at around 50% of all infections, were chronologically China, Ukraine, Thailand and Taiwan. Other countries like Italy, USA and France had infection rates that accounted for less than 40%, however, were on higher ranks from January 2011.
The security company, which drew an evaluation with the January 2011 rates, found that the total number of PCs infected were the same as that of January 2011 when the sources of infections were Trojans -CI.A (1,324 cases), Downloader.MDW (275 cases) and Lineage.KDB (113 cases).
Stated Boyd, PDF exploits were still troublesome, indicating a slight rise from January 2011. During February 2011 too there'd been employment of bogus Java scripts for contaminating computers with malware. The researcher added that as fresh assaults emerged daily, users required remaining careful, especially while downloading research applications that appeared doubtful. Help Net Security published this.
Nevertheless, the above figures aren't essentially an indication that security programs are getting more workable, instead they indicate that cyber-crooks are changing tricks.
