The convenience of u disk and large capacity of storage, by the vast number of users, almost every user will be one, but is so widely used, so that u disk is secretly targeted by viruses, more and more viruses through the computer, destroying important data through the file, in order to protect the data of U disk, Eliminate the U disk virus became the user's first task, the following teach you a small trick, the use of DOS commands to combat u disk
. The virus overwrites the original system file. Therefore, the operating system cannot be restored even if the antivirus software kills the virus.
Misunderstanding 2: anti-virus software is dedicated to virus detection and removal, while Trojan killing is dedicated to Trojan killing.

Web development applications (websites) are currently the most widely used programs. However, the levels of developers are uneven, leading to the emergence of various web vulnerabilities. This article analyzes how to find various vulnerabilities in
Recently, Jiangmin technology issued an emergency virus warning, a disguised as "panda incense" pattern of the virus is crazy crime, has dozens of of corporate LAN has been hit.

of anti-virus software.Today's anti-virus software is no longer just a virus concept. Nowadays, people often refer to the following anti-virus concepts: virus detection, real-time protection, network firewall, anti-Trojan, and an
worm, and Internet language virus: Some viruses written in Java, VB, ActiveX, etc, viruses can steal valuable personal confidential information through the network or reduce the utilization of computer system resources, resulting in a crash.
In particular, in recent years, viruses have emerged and are constantly evolving. Because computer data is highly mobile, as a common user, if you want to avoid computer viru
to the public. Today's viruses are different from those in the DOS and WIN3.1 era in terms of technology. I think the biggest change is that the boot zone virus is reduced, and the script virus is spreading. The reason is that it is difficult to directly rewrite the boot zone of the disk in today's operating system (DOS is not protected, and INT13 can be called to directly write the disk), and the changes
hiding technology: the backdoor of Windows 98. Second-generation process hiding technology: process insertion, and behind the hook technology is against anti-virus software against the dry: anti-virus software shell technology. The Trojan is cunning, but once the antivirus software defines the signature code, it is intercepted before it runs. To avoid anti-virus

Some people think that setting the file to read-only through the external DOS command ATTRIB can effectively defend against viruses. In fact, you only need to call a few DOS interruptions to modify the attributes of a file. Therefore, the ATTRIB command is almost powerless to prevent virus infection and spread.

Characteristics of the virus:
The biggest feature of the virus is self-replicating, from the classification of viruses there are many kinds, here we will introduce the most popular add-onVirus, which is adapted to the normal file to achieve its own replication purposes.From a procedural point of view, we have two things to do:
1, so that the program can be copied to other programs without affecting the wo
detected virus data to the feature database for virus detection and removal.
The biggest weakness of the pattern-Based Static scanning technology is that it cannot detect and kill "undisclosed" or "excluded" viruses, because most of its judgments come from virus-specific code databases, anti-virus software is powerles
