Laptop running slow

Posts Tagged ‘computer virus’

Regardless of the type of service that is used to connect with the Internet, there are several factors that can bring even the most robust connection to a crawl. Here are some examples of elements that can produce slow Internet service, as well as some solutions for these factors.

Perhaps the most common situations that can result in slow Internet service is the present of a virus on your hard drive. Computer viruses can be transmitted in a variety of ways, most commonly through an attachment to an email. The computer virus will integrate into key programs on the hard drive and silently use up a great deal of resources. By diverting some of the resources to running the virus, an Internet service slow down is inevitable. Fortunately, installing virus protection and removal software will help to remove viruses from the hard drive, as well as prevent new ones from infecting the system. As part of the task of preventing slow Internet service from occurring, it is important to make sure the antivirus software is updated regularly.

A senior research fellow in the U.K. says he has become the first person in the world to be infected by a computer virus.

Technically, the chip Mark Gasson inserted into his hand is infected, which one could argue keeps the virus limited to the domain of the chip even though it lives inside the man.

Dave, this is driving me crazy: when I first got my computer it was snappy and applications launched in just a second or two. Now, a year later, it’s like someone poured molasses over the hard disk without me noticing, because everything just seems to take forever. Why is my computer slowing down and how can I speed it up again?

Dave’s Answer:

One of the stranger aspects of computers is that they do indeed suffer from old age, as you are noticing. Oddly enough, the longer you use a computer – particularly a Windows PC in my experience – the slower it ends up running. It could be a plot forcing you to always buy newer and faster systems, but more likely it’s just that as you use the system, you put increasing levels of demand on the hardware with different helper apps, more running in the background, animated desktops, flashing icons, custom cursors, RSS readers and stock tickers, and even programs helpfully checking for updates at random intervals. It all adds up.

One strategy for improving things is rather draconian: back up your computer files, reformat your hard disk, then reinstall the OS from scratch and the key applications you use. Total time lost? Probably a couple of days by the time you get everything restored, but it’s really a pretty good annual task for PC users, in my experience.

Computer security is a branch of computer technology known as information security as applied to computers and networks. The objective of computer security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accessible and productive to its intended users. The term computer system security means the collective processes and mechanisms by which sensitive and valuable information and services are protected from publication, tampering or collapse by unauthorized activities or untrustworthy individuals and unplanned events respectively. The strategies and methodologies of computer security often differ from most other computer technologies because of its somewhat elusive objective of preventing unwanted computer behavior instead of enabling wanted computer behavior.

[edit] Enterprise Security Architecture

Evolution of technology, both in terms of hardware and software has complicated the data management scenario of Enterprise. Thus requiring a holistic, defensive, in depth approach. This approach incorporates: system, network, application, database, physical and logical security in terms of confidentiality, integrity, availability, accountablility and non-repudiation in terms of people, process and technology.

10. Use common sense. It’s always better to err on the side of safety. If you’re unsure about an attachment, delete it. Especially if it’s from a source you don’t recognize. If there are tempting animations on a site that look highly unprofessional, don’t download them.

9. Scan files for viruses before using them. This is always important, but especially if you are using a disc or flash memory to carry information between one computer and another. You could easily pick up a virus from a corrupted file and introduce it into your system. Running a virus scan before launching any of new files will prevent infection.

8. Don’t share data CDs. Even a well-meaning friend may unknowingly pass along a virus, Trojan horse, or worm. Label your discs clearly so you know they’re yours and don’t loan them out. If a friend passes you a foreign disc, suggest an alternative method of file sharing.

Your computer may have slowed down its execution speed below the expectation due to various reasons and complications. If your computer is running slower than usual and you are considering it to be inspected by a computer repair expert and spending money on getting your computer back to its normal level of performance, you should read about the common causes that make a computer slow.

While these issues may not be what’s causing your computer to run slowly, there is a chance that you can repair your computer without spending a single dime, instead a small investment of time and effort into looking at the following potential issues (please note that all of these issues concerns to PC/Desktop computers):

Has your Hard Drive reached its Maximum Capacity?

Hard drives with less than 500 Megabyte (MB) of free space on each partition (right-clicking the hard drive partition icon and navigating to the menu that displays the properties of your hard drive will give the free space estimation), can have a negative impact on the performance of your computer. Specially, less free space on the root partition where you have installed the operating system could lead to highly degraded performance.

Follow these steps and you’ll have your computer purring like a vintage Porsche (or whatever your dream car of choice is). And the best part? Maintaining your computer is a lot less messy than an automobile. You don’t even have to roll up your sleeves.

Clean up disk errors (Run once a week)

Whenever a program crashes, or you experience some power outage, your computer may create errors on your computer’s hard disk. Over time, the errors can slow your computer. Luckily, the Windows operating system includes a Disk Check program to check and clean any errors on your computer and keep it running smoothly.

Freeware to Speed up your Computer

Back in 2002, my computer was drowning. Drowning in countless start-up programs, temp files, cookies, caches, out-of-date Windows Registry entries, viruses, spyware….you name it, I had it. The Windows trash bin was full to bursting and the Clipboard was jam-packed. After only really embracing the internet in a big way the year before, I was having the time of my life, downloading and installing everything I could get my hands on. An executable email attachment called “Naked Britney Spears”? I’ll take that! A complete stranger telling me to download his “special new program”? Sure thing! Yes I was naive and very stupid back then.

But then a serious virus infection almost destroyed the hard drive and I realised I was being stupid and things had to be tightened up. Ever since then, I have been paranoid about keeping the computer clean from viruses and making sure everything is tidy, organised and fast. Now today I make sure the following programs are updated daily and are used at least every second day. Knocking on wood, I haven’t had a computer virus in four years or a spyware infection in two years. I am also a speed-freak, tweaking everything to make things go faster.
