Slow PC speed is always a stubborn and frustrated problems for computer users. Slow PC speed can be caused by many reasons that we need to know. However, To speed up the slow computer is another important thing. These are some tips that can help and guide you to improve your computer performance/running speed effectively. Read more
Victim: “My computer is loading EVERYTHING very slowly, yet i clean every part i can: ‘Disk Cleanup;’ temp files; under Document & settings – Local Settings – then Internet temp files; i even defragment once a week. Yet even bringing up ‘My Computer,’ causes the ‘search light’ to try to find files (about 30 seconds later, it does). I’ve checked for viruses and adware and have none (under AOL’s system). Is there something i’m not doing or that needs to be cleaned?”
Did you ever encounter such issues? Your computer always runs fast? Or it moves slowly like a snail? If your computer moves slower and slower, have you ever thought about the reason? This post will give some common reasons that may cause your slow PC.
1. Too many add-ons on your browser.
Not all browser extensions are created for good. “People often assume a slow computer is because of a virus, but a lot of time it’ll be a browser add-on or plugin bundled with a free software download,” Silverman says. These add-ons may proclaim themselves popup blockers or search protectors, but they’re actually browser adware that can slow your computer down by downloading ads and popping up ads every time you open your browser.
2. Too many startup programs
Newly downloaded programs often try to weasel their way into your Startup menu (Windows) or Login Items (Mac). If you didn’t uncheck the box for that permission, you could have dozens of unnecessary programs vying to be ready and running as soon as your computer boots up (as if that’s happening any time soon).
While some programs – such as antivirus and firewall software – should be allowed to run from startup, others – such as iTunes or Microsoft Office – could quite easily stay closed until you actually need to access a file from their digital depths.
3. Too many background programs running on your computer
Remove or disable any startup programs that automatically start each time the computer boots. If you you have a security utility, malware and spyware protection program or an antivirus scanner on the computer, set it up not to scan your computer in the background. Often when these programs begin to scan the computer it can decrease the overall performance of your computer.
4. Your computer is Infected with a Virus or Malware
If it’s not the antivirus, it could be the virus. Viruses, spyware and other malware can slow down your computer as they mess around with everything from hijacking your browser to pushing advertising or phishing sites, to crashing your computer. Today, spyware and other malware is a big cause of many computer problems including a slow computer. Even if an antivirus scanner is installed on the computer we recommend running a malware scan on the computer.
5. Hardware conflicts and outdated drivers
A hardware conflict occurs when two devices try to use the same resource, such as an IRQ or memory address, producing an error. For example, if a hardware device in the computer shares the same IO port as another device that would result in a hardware conflict. In modern day hardware conflicts are less common because by using plug-n-play (PnP) manages each of the hardware devices installed in the computer for the user.
All in all, there are still some reasons that I haven’t listed above. And the reasons I listed above may be the common ones. You can take a reference. And I hope those information can be helpful for you.
Nowadays, more and more people do many things such as shopping, booking a ticker through various applications installed on their mobile phones. However, many people cannot realize that there are still some risks. Cybercrooks now not only attack computers, but also attack mobile phones or other mobile devices. We lists two examples like below.
1. Mobile phishing or scam
Just like the PC scams, bad guys are using social engineering through mobile apps and SMS text messages, which take advantage of human behavior and trust to gain access to data or infiltrate businesses, to make people click on links. Malware then ends up on the user’s PC. This trick has been used with email, instant messaging, social networks, and [now] they are even spoofing SMS text messages.
For example, more and more users stated that they keep receiving information about win a prize on their mobile phone. And the informed message contains some of your personal information. Why? Because your privacy might be leaked out from some login information on the Apps of your phone, such as your phone number, your name, email address and so on. Cyber criminals may make use of those personal information to earn your trust. Or sometimes your confidential information of online bank might be exposed as well.
2. Using an infected mobile device to infiltrate nearby devices
When working inside a company to identify vulnerabilities, pentester and mobile security expert Georgia Weidman recently asked herself from a hacker’s perspective, “wouldn’t it be nice if we could just walk into the network with a compromised phone and have direct network access” by way of a client side attack or social engineering. She concluded that in many cases you can. “An infected mobile device allows you to breach an organization’s perimeter and directly attack the devices on the network instead of having to break in some other way, you’ve already got direct network access,” Weidman says.
Personal computer is designed for an individual users, which is small and relatively inexpensive. Personal computer first appeared in the late 1970s. One of the first and most popular personal computers was the Apple II, introduced in 1977 by Apple Computer. During the late 1970s and early 1980s, new models and competing operating systems seemed to appear daily. Then, in 1981, IBM entered the fray with its first personal computer, known as the IBM PC. The IBM PC quickly became the personal computer of choice, and most other personal computer manufacturers fell by the wayside. One of the few companies to survive IBM’s onslaught was Apple Computer, which remains a major player in the personal computer marketplace. Personal computer is relatively inexpensive in its price. It range anywhere from a few hundred dollars to thousands of dollars. All are based on the microprocessor technology that enables manufacturers to put an entire CPU on one chip. It is also convenient that used at home for playing games. And businesses use personal computers for word processing, accounting, desktop publishing, and for running spreadsheet and database management applications. Nowadays, as the development of economic and technology, more and more people can buy a personal computer for more convenient life.
