If your system is experiencing remarkable slow speed or opening random pop-up pages that could mean virus attack. Viruses do grave harm to computer systems from corruption of files to hard disk and operating system crash and many more
This can be disastrous especially when a lot of data is involved. However, you should know that there are some problems that are better avoided rather than experienced. What I mean is that you can prevent virus attack – I covered that in How To Protect Your Computer From Malwares – Viruses, Spywares etc go and read it.
The question now is what are you to do if such a case is recorded? Can you do it yourself without calling your system engineer who would capitalize on your desperation to charge you exorbitantly? The answer to both questions is yes. Yes you can!
Carefully go through these 6 steps to resolve the problem.
STEP 1: Restart Your System On Safe Mode
Disconnect all network connections, internet, Wi-Fi and prepare the system to be run in Safe Mode. Safe Mode allows your system to run with fewer programs and processes. Shut the system down or restart and once anything shows on the screen press F8 repeatedly. Advanced Boot Option menu will appear, then select Safe Mode with Networking and press Enter. For Windows 8 and 10 once the Windows login screen appears, just choose restart and hold down the Shift key. This will take you to the window with options to troubleshoot and from there you can choose the boot in Safe Mode option. Since malware will not run in Safe Mode, you will be able to discover what the problem is in this mode.
STEP 2: Check and delete temporary files
You can clear your system of temporary files that fill up your disk space, ease virus scanning and can delete malware in the process. Here is how: Start>All Programs>Accessories>System Tools>Disk Cleanup. Once there, choose delete temporary files.
STEP 3: Scan your system with Malwarebytes
Since your system has already been infected by virus which your installed anti-virus could not detect, your best bet now is to download Malwarebytes Anti-Malware free on-demand scanner. It is either you re-connect to the internet to download or download using another system then copy and transfer it through a USB flash drive, then install the app in the infected computer.
After installation Malwarebytes will check for updates and launch itself. If it indicates that the database is outdated, follow the instructions to download the updates. After opening, select ‘Perform quick scan’ then click Scan. This option takes between 5 and 20 minutes depending on your system while the full scan takes as much as 30 to 60 minutes. While the app is working it will be displaying how many files or objects it has scanned and identify the ones that are malware and those infected by malware.
It could happen that Malwarebytes disappears automatically after it began scanning and never re-opens, there is a rootkit or deep infection that automatically kills scanners so that it cannot be removed. What you need to do is to reinstall Windows, but back up your files first. If after the quick scan Malwarebytes did not find any infections as indicated in the scan result, you may consider running a full scan. If it finds any infection it will show them in the dialog box. You can see all the scan’s discoveries by clicking the Scan results button. The software automatically removes dangerous items and you can select to remove other infected files. Check all the removed items to be sure the scan was successful.
Malwarebytes will prompt you to restart your system to complete the removal process after everything. Restart to confirm. If the problem still remains what you can do is to do another scan with Malewarebytes and other anti-virus programs. Check and confirm the result afterwards, if successful then skip to step 5 but if not proceed to 4.
STEP 4: Install Anti-Virus
If step 3 did not work-out for you, then you have to buy a bootable USB stick with pre-installed security software. It scans and cleans your system offline. One of such is FixMeStick, a plug and play USB device that operates in its own clean environment detecting viruses and malwares. If you feel it is too expensive at £45, then you can create yours by downloading and installing the software into a USB drive.
STEP 5: House Cleaning
Now that you are ‘free’ from virus, do not celebrate because you might not be free from the after effect of the virus. Go to your browser and remove any unwanted web browser toolbar, return your search engine back to its default state and remove totally any strange search engine from your browser (go to settings on your browser to do that). Finally change all the password and login details from all your accounts be it social media, emails or even online payment platform password – anything that requires password.
STEP 6: Prevention is Better than cure
Would you rather go through this process or avoid it totally? You can be better off by installing internet security such as firewall, antivirus, antispyware etc on your system. Buy and install an internet security suite since you use your system to browse and use USB drive from other systems. Avoid using an outdated antivirus and USB from others or your USB on someone else’s system. Read: How To Protect Your Computer Against Virus to know more.
