July 24 news of Beijing time, the senior products manager James and Plate (JamesPratt) of Microsoft Write articles and claim in the official blog of this company, since putting out in Microsoft IE8 on Friday, this browser is attached " the intellectual screen filter " (SmartScreenFilter) Have already succeeded in preventing hostile software download 1 billion times from being attempted.

The operating principle of IE8 intellectual screen filter is, this tool will carry on assessment and analysis to website and relevant server that users visit. If this filter finds that contains the hostile software in a certain server, will send out and remind to users, claim if users continue visiting a certain website, will jeopardize the security of user's machine. The filter will select for two users: Continue, browse through website this, recycle homepage that users set up back to, do not download any content in this website.

Plate claims, the application number of IE8 intellectual screen filter is increasing rapidly. He shows, in August of 2009, this filter succeeds in preventing hostile software download 70 million times from being attempted, in all netizens in the whole world at that time, only 15% used IE8, this rate has already been increased to 26% at present; After user quantity increases, the quantity of hostile software download that IE8 intellectual screen filter prevents is more than 5 times of August of 2009 at present.

Plate shows, it explains two questions that IE8 intellectual screen filter prevents hostile software download from reaching 1 billion times: First, the hostile software is still one of the important problems of threatening the security of netizen; Second, IE8 can protect the netizen effectively on net and safe. Plate still proposes, those are still user of inuse IE6 or IE7 edition, should be to IE8 staging in time.

The compiling of hostile software deletion tool through Microsoft instead, Microsoft chooses August causes 10 kinds of most severe hostile software of danger to Windows system recently.

According to hostile procedure kind, that occupy the first place in a contest is still Win32/Taterf, it is one of the most common hostile procedures on Internet to steal the software in Taterf password. The expert thinks, present detection means is unable to examine the similar act of theft, it is to impel its important auxiliary boost factor that overflows to be very apt to profit and not have any risk.

In the second is Win32/Renos, it is the advertising software of a evil intention, found in March of 2007 initially. This virus adopts the process interlocking, and it is false to spring regularly to warn, lure users and click to install other software.

Miscellaneous the intersection of Koobface and worm-type virus that break out will it be May this year, the intersection of virus and the intersection of mutation and more pole this. Koobface worm spreads to the good friend in good friend's tabulation through the legal account number. Inveigle the good friend and click unidentified interlinkage. Once the intersection of user and computer infect, worm this will further travel to him or good friend of her through the intersection of account number and the intersection of onward transmission and message or information this kind of of user this.

It will produce a positive impact at least to sweep across the global economic recession at present, that is to impel the hostile software quantity to drop. An analyst of the German software security firm G Data shows, between June and May of this year in the near future, the hostile software quantity has been reduced by 30%. Meanwhile, G Data Company think the decline of the hostile software quantity is the natural decline produced in season on vacation.

As to this, analyst Ralf Benzm of G Data Company Ller was explained and claimed, identical economic force has not merely influenced the legal part in the economic system, this whiff of economic force influenced the hostile software too at the same time, led to the fact the hostile software quantity drops. Make hostile software, need fund, but present economic recession lead to the fact criminal make the investment make hostile fund of software, reduce. Because of lacking and making the required fund of hostile software, so the decline appears in the output of the hostile software.

Benzm Ller claims in a formal report: "The operation of black economy accords with the economic principle of ' the demand ' too: Supply-demand relationship is determining the business. So can not escape on the influence of sweeping across the global economic crisis at present either naturally in electronic crime economy. "

He claims: "After price crash appeared at the price which sent the junk email, the economic recession influences the hostile software author too now. The order of this special trade seems to be dropping at present. In view of the above, we are expected in this month the new hostile software quantity will stagnate. Our company detects the hostile software sample has been reduced from 123581 in May to 83072 in June. However, this figure is only slightly lower than April detected 93785. "

If Benzm Ller analyzes the accurate, the quantity of so hostile software will drop or keep the state of stagnating continuously. No matter drop or stagnate, are undoubtedly all a good news. An obvious evidence is that different typological hostile software will present this long phenomenon that he disappears.

Because the criminal has no fund to make new hostile software, then these criminals will turn to before this the hobbyhorse virus that is the downswing again, lower priced electronic crime means such as other typological technology relatively mature hostile software, and junk email,etc.. Better detect and filtration technology will force criminals to send more junk emails, so the ascendant trend will appear in the quantity of the junk email.

In addition such as DDoS etc. typological attack, extort directly, and the intersection of target and clear attack may the ascendant trend will appear too. The statistics data display of G Data Company, adopt the electronic criminal activity of these means and has not increased sharply yet at present. Will present the deflection usually as to future prediction like in the normal economic environment.
