What Harms Does Virus Attack Bring To Shared Hosting？
With the robust advancement of computer science and information technology， the computer virus has become the most dangerous potential risk threatening the information security. Basically， the virus attack can cause certain damages to the shared hosting or server， for it not only has infectious， latent， and triggerable characteristics， but also may bring severe threats such as attacking files， slowing down the system‘s speed， damaging network systems， and disrupting the normal operation of computer systems. In this regard， we must take measures such as data backup， regular virus killing， establishment of multi-level virus protection， and cultivation of a good virus defense awareness to prevent the intrusive computer viruses. Below， we will make some explanations on some aspects.
1. Attacking File
The file-attacking has various forms and the file virus is the very typical one among them. In general， computer’s source files， system files， document files or executable files may all have the possibility to become the object of a virus attack. After being compromised， the contents of those files may be destroyed or modified for sure， and its save time may also be changed.
2. Slower System Operating Speed
The virus may attack computers by occupying， changing and allocating the memory， as well as slowing down the operation and processing speed of the computer system. Under this circumstance， some programs shall fail to operate normally due to the relatively small system memory.
3. Destroy Network System & Disrupt Normal Operation of Computer System
Some viruses attack and destroy network systems by occupying network lines and illegally utilizing network resources， which will finally result in the network paralysis. In most cases， the computer may be trapped in the downtime， refuse to execute commands， format the hard disk， get the keyboard locked up and fail to display the corresponding contents due to the virus invasion.
Anyway， the widespread use of the network makes the spread of the virus easier and more convenient. Due to its great bad social effects， we must take measures to prevent computer viruses at all costs.
