What This type of malware consists of characterics associated with serveral categories of malware?
This type of malware, often referred to as hybrid malware, combines characteristics from various malware categories, such as viruses, worms, Trojans, and ransomware. It can replicate itself, spread across networks, and may also encrypt files or exfiltrate sensitive data. By incorporating multiple functionalities, hybrid malware can evade detection and adapt to different network environments, making it more challenging to combat. This complexity enhances its potential for damage and complicates remediation efforts.

Who discovered the computer virus at first?
The first virus was made in Chauburji, Lahore, Pakistan, 1986
Two programmers named Basit and Amjad Farooq Alvi, .replace the executable code in the boot sector of a floppy disk with their own code designed to infect each 360kb floppy accessed on any drive. Infected floppies had " Brain" for a volume label.
What a virus cannot do on its own in computers?
Like a real world virus, computer viruses heavily rely on a "host" file in order to propagate. In the wild, if a computer virus cannot attach and inject itself into a host file, it will just roam around and eventually get destroyed by an antivirus program. Computer viruses cannot replicate without a host. Worms on the other hand are independent programs that can replicate freely without the need of a host like a virus. When it comes to lethality though, a virus is more destructive than a worm.
I downloaded it once and a huge virus got on the computer and took all weekend and everything erased to fix it... I think it was from feralheart, speaking their are a lot of complaints about viruses being on people's computers after downloading it.
What are some ways people can mitigate their impact on the biosphere?
There is a movement in the US to utilize the "Three R's"... Reduce, Re-use, and Recycle... As water is the... the HUMAN's... most dire resource, USE LESS of it by turning OFF the water while you brush your teeth, TURN IT OFF while you lather up during shower time, and USE A BROOM to sweep your sidewalks. Drought-resistant plants and shrubs in your landscaping results in LESS water usage as well. These simple procedures establish a great way to FOCUS on the ISSUE.
How does a computer virus get on your machine?
It is a program or command that can get in from infected software or e-mails. You can keep these nasty and time consuming devils off of your computer by doing 3 things. Get the free firewall called Zone Alarm, Get the free program Ad-Aware and run it often. Finally get the free program Hijack this. These 3 freebies will keep trash off of your computer.
How do you get rid of viruses on your computer?
When you first bought a computer it should come with CDs to repair/reinstall your computer. You need those CDs to reset your computer again to new state. If you don't want to, you can download Anti Virus Programs, such as Norton. But please keep in mind that not all Anti Virus can remove all of your viruses, some of them can be virus made programs itself.
How do computer viruses infect and spread in computer systems?
A virus has a specific string or line of code. When a virus enters a system, it is usually coded to infect a certain part of the computer, for example, the boot sector. When a virus reaches its destination, it injects the code. The virus itself isn't harmful, the code it injects is. Viruses don't replicate. Worms do that.
Yes, just make sure you do a full scan
What is the first step you take when your computer is infected by a virus?
Quarantine an infected system. Then use use antivirus software and antiadware software to do a general cleanup. If the system is highly infected and will later hold sensitive data, consider backing up the data, reformatting the hard drive, and reinstalling the OS and applications. In fact, Microsoft recommends this to be the safest way to deal with highly infected systems.
What are the benefits of computer viruses?
There are none. Viruses are never technically 'alive'. They are tiny microbes that enter the body and only start reacting to the environment once they have entered a protein molecule. They then use the molecule duplicate themselves and spread around the body. They have no life processes like other microbes, such as bacteria or fungi. They are the 'zombies' of the microscopic world.
How you can know your system is infected by virus?
I would suggest you run housecall it will scan your computer for viruses and tell you what they are if there are any. It is free and found it to work very well http://housecall.trendmicro.com/. After doing that if there are viruses found you should run Adaware. This can be downloaded from download.com and is also free.
Try the following programs-they will stop all unwanted stuff from getting on your PC-I went to www.webattack.com and found a way to remove it by doing the following-clicked on green link at the top of the page stating "FREEWARE",then clicked on virus tools/or you can search on that site for this program-"Avast home edition".It is the best freeware program,that i have ever used and removed the virus in no time.The Funweb A is a Trojan horse virus,and when Avast picked it up was goung under another name-i think that's why everybody have difficulty in removing it,and cant find anything under funwe A ,coz it is going under another name.Avast has also detected and removed 2 other virus infected files on my PC!It is important to do a live update of avast virus deff and to set program to run a full system scan.Do download the full free home adition and not just the computer cleaner.Its AMAZING and kicks budd! : )Thank you so much Avast!!!!Two programs going really well with Avast and also freeware on the same site is Ad-Aware spy detector and Zone Alarm firewall.I have all three and they work together like magic!: )GREAT STUFF!!!!Try it,you wont look back!just scan the whole PC.

What do computer viruses do to your computer?
They do different things. The most recent "viruses" are really technically called "worms". These programs are usually loaded as attachments in emails, and then silently send out emails to everyone in your contact list. Other viruses attach part of their code to your device drivers, or commonly used programs, so that whenever you run that program it runs as well. Some will delete or rename important files, some will broadcast your information out to other computers, and some will attempt to perform operations that could damage your hard drive, etc.
trojan. this is a bad bad one i have ahd i before. basicly it hides it self in files ( like the trojan horse) and can delete, copy files or worse destroy your machine. however if u do a full scan it will pick them up and u can get rid of them. but this is a common one
What are the different names of viruses?
Some free anti-viruses include AVG, Malwarebytes, and avast!. AVG and avast! also have versions available for purchase, and Norton has many antispyware and antivirus products that you can buy.
Flies are generally considered to be pests, but they do serve a purpose. This purpose is served in the ecosystem. When flies lay their eggs, maggots help to break down garbage and organic matter. Flies also help to pollinate crops as fly around them.
What can you do to prevent a computer virus?
Before you browse to the internet the best and safest way to do is to install anti-virus. There are many anti-virus in the market, you can have free trials or purchase you own copy. Be picky when you buy anti-virus software.
What are the three types of computer viruses?
Types of computer viruses are:
Macro Viruses: Macro Viruses use commands (macros) embedded in other software to infect and spread to other files viewed by that software. E.g. Word and Excel have macros and macro viruses can spread by exploiting these commands..
Worms: Worms duplicate themselves and use communications such as email to spread. They can look at your email address book and send themselves to users in your address book.
File Viruses: File viruses attach themselves to other software. When the software is run, the virus first loads itself into memory so that in can further infect other files or begin damaging the computer.
Trojan Horses: Trojan Horses are programs that claim to perform a particular function but in fact do something different. E.g. they could infect your computer with a virus or erase your files.
Backdoor Trojans: Backdoor Trojans are programs that allow other computer users to remotely control your computer via a local area network or the Internet. . . . Boot Sector Viruses: Boot Sector Viruses are an older type of virus and not so common. They used to infect a computer's startup program so that the virus would become active as soon as the computer started up.
Adware: Is to internet browsing as spam is to email Adware can profile your online surfing and online shopping habits and or placing annoying pop-up adverts, installing additional IE menu helper bars. Often Adware revolves around targeted advertising based upon the web sites you frequent and you may not even be aware that the pop-ups are not coming from the actual web site visited itself but from the Adware software running locally on your machine. Quite often these applications are installed by stealth or by deliberately misleading users to install software that is not required. Spyware: Is potentially a higher threat than Adware as it often collects user details, such as software installed and often sensitive information such as passwords and even credit card details which are then sent to via the internet to a central collection point. Spyware is often installed covertly or by accident via pop-up windows with active-x controls which report that they are doing something benign whilst secretly installing this malicious software.
Page Hijackers: Are applications that redirect links to specific web pages, such as a request to go to a search engine for example, and instead redirect the web browser to a designated address, related to the initial link but often containing advertising or adware. Whilst not as high a threat as Spyware, it is often a sign that your computer has some spyware or adware components installed on it which will undermine its operation.
AnswerIf you are asking about types of computer viruses there are File viruses Multipartite Viruses and Macro VirusesCompare and contrast a computer bug and a computer virus?
A bug is a glitch in a program caused by a design flaw. Bugs can cause programs to crash or not work properly. A virus, on the other hand, is a program which was designed to cause problems on your computer. Viruses may steal your information and transmit it to another person, or they may be used to allow another person to take control of your computer.
What are the differences between polymorphic and metamorphic virus?
The affect of a polymorphic virus on a computer is exactly the same as any other virus. That is, that it is capable of the same processing as any other piece of software.
The name polymorphic or in English "Many Shapes" refers to the virus's programmed ability to alter its own code when replicating itself to avoid detection.
Most simple antivirus programs use a sample of code to match against a suspected file to identify a virus. Changing the code makes detection impossible using this technique.
A more accurate method of locating a virus is to examine the code and programmatically detect what the code does. For instance if within the few lines it instructs the computer to wipe the hard drive it is 99.9% likely that this is malicious. A statistical assessment of the code is made and if the code breaches the chances of being highly malicious, then the code is flagged for removal.
This technology is called Heuristic analysisand is not without it's problems. The trigger level between virus and non-virus can be set too high or low, resulting in false positives or failure to detect malicious software. False positives can be triggered by software that does some to the things that Viruses are likely to do, such as formatter programs or communicating with a centralised server.
Overall the combination of both systems plus a register of known good and bad software is the most effective at detecting virii.
