Windows will occasionally get infected with viruses or other malware, but not every slow or misbehaving computer is affected by malware. Here’s how to check if your computer is infected with a Virus and if there are any suspicious processes that are dangerous to Windows?

What are the signs that a computer is infected with a Virus?

Poor performance, application crashes or a computer suffering from a blue screen of death can sometimes be a sign that the computer is infected with a Virus or another type of computer. malware others are destroying your data. However, that is not always the case: There are many other causes problems that can slow down Windows.

Likewise, just because Windows is working well doesn’t mean it’s free of malware. The viruses of a decade ago were often jokes that ran around and used up a lot of system resources. Modern malware is more likely to lurk silently and secretly, trying to evade detection in order to obtain your credit card numbers, passwords, and other personal information. In other words, today’s malware is usually created by Hackers just to make money, and well programmed malware won’t cause any noticeable computer problems.

However, sudden poor computer performance can be a sign that windows is infected with a virus. Strange applications on the system are also signs of malware. Some applications pop up a Command Prompt window when they update. Some strange windows flashing on the screen and quickly disappearing may be a normal part of legitimate software on your system, such as driver installers, software updates… we don’t assess whether they are toxic or not.

There is no convincing evidence without using Virus scanning software to see if your computer is infected with viruses. Sometimes malware causes problems for the PC, and sometimes it works stealthily to accomplish its goals. The only way to know for sure if you have malware is to check your system for it.

How to check if a process is a Virus?

You may be wondering how to know if your computer is infected with a Virus? Try to check for strange processes in Task Managerby pressing Ctrl + Shift + Esc or by right-clicking on the Windows Taskbar and selecting “Task Manager“.

Usually you’ll see quite a bit of progress here – click “More Details” if you see the list is smaller. Many of these processes have strange, confusing names. It’s okay, Windows has quite a few processes running in the background, and the process is broken down into several tasks.

Malicious software often uses a large amount of CPU, RAM or disk resources and can be prominent here, if you see a process consuming too much RAM, CPU, DISK, you have the right to be suspicious. If you’re curious about whether a program is malicious, right-click it in and select “Search Online” to find more information.

If malware information comes up when you search on Google, it’s a sign that Windows may have malware. However, don’t assume your computer is virus-free just because a process looks legitimate. A process can be anonymous with the name “Google Chrome” or “chrome.exe”, this could just be malware impersonating Google Chrome located in another folder on your system. If you are concerned that there may be malware, AnonyViet recommends that you perform a scan with anti-virus software.

Option Search Online not available on Windows 7. If you use Windows 7, you will have to manually type the name of the process into Google or another search engine to find out if there is any information about the name of the process on the Internet.

How to scan Virus on Windows

By default, Windows 10 will always scan itself for viruses for malware using the built-in Windows Security app, also known as Windows Security. Windows Defender. However, you can perform a manual scan.

On Windows 10, click open Start Menu, type “Security” and click “Windows Security” to open it. You can also go to Settings > Update & Security > Windows Security > Open Windows Security

To check if your computer is infected with Virus or not, you need to conduct a malware scan, click on “Virus & threat protection”.

Click “Quick Scan” to scan your system for malware. Windows Security will perform the scan and give you the results. If it finds any malware, it will automatically offer to remove it from your PC.

If you still have doubts after the scan is complete, your computer still has malware, please use 3rd party antivirus software. AnonyViet has a list of TOP Paid anti-virus software and free of charge best for your reference

I recommend Malwarebytes, works well with Windows Security to provide an extra layer of protection for your Windows. The free version of Malwarebytes will allow you to perform a manual scan to check for Viruses and other malware on your computer. The paid version adds real-time protection – but if you just want to check your computer for malware, the free version will work perfectly.

Windows 7 No built-in anti-virus software. For free antivirus software, you can Download Microsoft Security Essentials to scan for viruses. This provides the same protection as the Windows Defender security software built into Windows 10 to avoid the computer being infected with Viruses.

If your Anti-Virus application finds malware but cannot deal with it, try performing a scan in “Safe Mode”. The safest thing is to proceed Reset Windows 10 to the default state.

The problem of ants and electronics is a long-standing problem. Ants tend to build homes in warm and compact spaces, which is why they love laptops and PCs.

With an estimated 10 billion billion ants on the planet, this problem is much more common than you might think.

Prevention is better than cure

Ants will search your house for two things: food and water. Since your computer is not a source of moisture, food can be a major cause of ant-related problems.

Laptops and keyboards in particular can get food debris between the keys. Spilling sugary and alcoholic beverages near or on the keyboard can also be a problem as you can’t get rid of all the liquid without removing the key (you can also try using a hair dryer to dry the keyboard).

One simple step you can take is to avoid eating food near your laptop or keyboard. For peace of mind, don’t even leave food in the same room as your computer. Ants won’t last long in an environment without food and drink.

Simple ways to deal with ants

If you notice ants clinging to the connection ports of your laptop, case, or handle, this could be a sign of a much larger problem.

You can purchase ant repellents and other products, but be aware that you need to call in professionals to deal with large ant colonies.

Ants will leave scent trails for other ants to follow, a phenomenon you can see by watching them move across the surface of a wall or table. Removing these stains with a 1:3 mixture of white vinegar and water (or cleaning spray) can make it harder for them to find their way back to your desk or computer.

Failure to handle the main source of ants in your home is failure. Any effort you put in to solve the problems in your electronics may be in vain as the ants will keep coming back.

Getting ants out of your computer

If your problems are relatively minor, there are a few ways you can try to solve them before things get out of hand. You should try if you notice a few ants coming in and out of ports or around your computer.

You can try to pick up your laptop and shake it vigorously from any charge, this will affect the ants inside. And these ants will want to get out of that environment as quickly as possible, and they will be able to find their way out due to the scent trails they leave when they arrive. You can try this a few times and observe the results.

Another option is to use the heat inside your laptop to make the ants so uncomfortable they want to leave. You can stress test the system to make the laptop work at full capacity and generate high temperatures.

On a Windows laptop, you can play games and increase the graphics, or Blender and try rendering some demo files, or use PowerShell to stress test 100% CPU.

On Mac and Linux this is possible using the UNIX . command yes. Simply launch a Terminal window, run yes and wait. You can launch a few more windows to get the fan spinning. Close the Terminal window to end the stress test.

Some users recommend blocking the heatsink holes and ports on the laptop. But I advise you to think carefully before deliberately heating the device in this way. It can void your warranty and damage the hardware inside the laptop.
While it’s true that ants like warm spaces, they can’t regulate their internal body heat, meaning they don’t thrive in very hot conditions. This will let the ants know that a place that is too hot will not be suitable for nesting.

Coping with bigger problems

If the condition becomes more severe, you may see a lot of ants moving in the vents and ports. The ants that come and go are usually ants that go in search of food and water to bring back to the colony. If you see ants carrying stuff into your laptop, there may be queens or eggs inside your computer.

It’s probably best to do this on a nice dry day. Some guides recommend vacuuming your computer to keep ants out, but you need to be careful with this because dust particles sucked into the machine can cause a build-up (and discharge) of static electricity.

Instead, carefully disconnect or remove the battery (or remove the power cable on the desktop) and use a soft plastic tool to remove any eggs you find. Ants will immediately run away when you open the case, but you can also use an air compressor to blow them up.
Air compressors can be dangerous when used near sensitive objects (such as propellers) so be careful. After you do a swarm of ants, they are still likely to come back because the queen ant is still on your computer. So, clean your computer periodically to avoid similar problems.

There is no SUBSTRING function in Excel. Use MID, LEFT, RIGHT, FIND, LEN, SUBSTITUTE, REPT, TRIM and MAX in Excel to extract substrings.

How to handle substrings in Excel

Mid

To extract a substring, starting in the middle of a string, use the MID function in Excel.

Explanation: the MID function starts at position 7 (O) and extracts 6 characters.

Left

To extract the leftmost characters of a string, use the LEFT function in Excel.

To extract a substring (of any length) before the dash, add the FIND function.

Explanation: the FIND function finds the position of the dash. Subtract 1 from this result to extract the correct number of leftmost characters. The formula shown above will become LEFT(A1,4-1).

Right

To extract the rightmost characters of a string, use the RIGHT function in Excel.

To extract a substring (of any length) after the dash, add LEN and FIND.

Explanation: the LEN function returns the length of the string. The FIND function finds the position of the dash. Subtract these values ​​to extract the correct number of rightmost characters. The formula shown above will become RIGHT (A1,6-4).

Find substring between parentheses

To extract a substring between parentheses (or curly braces, curly braces, slashes, etc.), use Excel’s MID and FIND.

1. The recipe below is almost perfect.

Explanation: the FIND function finds the position of the brackets. Add 1 to find the starting position of the substring. The formula shown above will become MID (A1,6 + 1,2). This MID function always extracts 2 characters.

2. Replace parameter 3 with a formula that returns the length of the substring.

Explanation: subtract the position of the opening brace and the value 1 from the position of the closing brace to find the exact length of the substring.

Substring containing specific text

To extract a substring containing specific text (e.g. @ symbol), use SUBSTITUTE, REPT, MID, FIND, TRIM, and MAX in Excel.

1. First, use SUBSTITUTE and REPT to replace a single space with 100 spaces (or any other large number).

2. The MID function below starts position 50 (1/2 * large number) before the position of the @ symbol and extracts 100 (large number) characters.

3. Use the TRIM function to remove leading and trailing whitespace.

4. Put it all together.

Note: in step 2, the MID function starts from position 50 before the @ symbol. If the email address is the first word in the sentence (cell A3), this results in the wrong starting position. In this case, the MAX function (see formula above) returns 1.

Flash Fill

If you don’t like using formulas, use Flash Fill in Excel to automatically extract substrings.

Note: Excel does not insert formulas, if you change the text string in column A, Excel will not update the value in column B.
