We spend an enormous amount of time fixing computers with viruses which could have been avoided if these precautions had been followed.
What is the purpose of a virus?
It is predominantly to steal from you, it will try to get your personal details to clone your identity, it will try to obtain your bank details, these programmes are so sophisticated they are even able to monitor your web activity even to your keyboard activity even de-encrypt keystrokes on a secure site and even watch and listen through your webcam fortunately that particular one is rare but malware/viruses are getting more sophisticated.
What are Computer Viruses?
Computer viruses are programs written by “mean” people. These virus programs are placed into a commonly used program so that program will run the attached virus program as it boots, therefore, it is said that the virus “infects” the executable file or program.
What Do Viruses Do?
Viruses have many purposes-some are designed to play annoying tricks, whereas others have destructive intent. Some viruses present themselves as jokes while performing secret destructive functions. There two major types of viruses, one being compiled viruses, which are executed by the operating system, and another being interpreted viruses, which are executed by an application.
How do Viruses Spread?
Viruses insert themselves into host programs and propagate when the infected program is executed, generally by user interaction (e.g. opening a file, running a program, clicking on a file attachment).
How do I prevent a virus?
- Load only software from original disks or CD’s. Pirated or copied software is always a risk for a virus.
- Execute only programs of which you are familiar as to their origin. Programs sent by email should always be suspicious.
- Computer uploads and “system configuration” changes should always be performed by the person who is responsible for the computer.
- Password protection should be employed.
- Check all shareware and free programs downloaded from on-line services with a virus checking program.
- Purchase or download a anti-virus program that runs as you boot or work your computer. Up-date it frequently. There are free anti-virus programs available.
What are Trojan Horse programs?
Named after the wooden horse from Greek mythology, Trojan horses are non-replicating programs that appear to be benign but actually have a hidden malicious purpose. Some Trojan horses are intended to replace existing files with malicious versions, whereas other Trojan horses add another application to a system without overwriting existing files. Trojan horses are often difficult to detect because they appear to be performing a useful function
What are Malware programs?
Malware is short for malicious software. Malware, in general terms means forms of hostile, intrusive or annoying software that have malicious intent. Viruses, Trojans, and Key-loggers are just examples of Malware.
What are Phishing programs?
Phishing refers to use of deceptive computer-based means to trick individuals into disclosing sensitive personal information. To perform a phishing attack an attacker creates a Web site or e-mail that looks as if it is from a well-known organisation, such as an online business, credit card company or financial institution. The fraudulent e-mails and Web sites are intended to deceive users into disclosing personal data, usually financial information. For example, phishers might seek usernames and passwords for online banking sites, as well as bank account numbers.
Fake antivirus is a threat that comes under the guise of a antivirus program and has become increasingly prevalent over the past year. Offering to locate and remove malware from your PC this rogue will actually install a Trojan on your unsuspecting system. The process is usually initiated when you click a link for what you believe is valid security software or its vendor’s site it will ask for a payment to enable you to remove the so called problems it has found when in fact the programme itself is the problem do not fall for this ploy they will have your credit card details and your situation will not have improved.
How can we help?
We have fixed many computers with viruses etc for many years. We have never been defeated by one yet. We have sadly listened to people who have told us they lost all their files or paid a lot of money for scareware removal (see scareware) and lost their money or had to cancel credit cards. If in doubt contact us it won’t cost anything to ask advice. If you think your computer is infected it may be displaying unusual behavior or there are symptoms like slowing down, it quite possibly needs disinfecting.
We would be happy to diagnose and if necessary repair just give me a ring on 0121 744 0377
