Fixing browser shortcuts altered by malware.
What can actually happen is that the malware might have altered the target field and included a malicious URL in it. What happens is that now your browser will start up on this page each time you boot it up.
Normally, the browser target should look something like this:
Chrome: C:\Program Files \Google\Chrome\Application\chrome.exe
In our example case, the browser was targeted to go to a suspicious website, aimed at downloading malware on your PC.
You can fix that by simply remove the URL that comes after .exe.Browser hijackers will change the homepage. Instead of changing the Target field in the Shortcut tab, some malware might just modify your browser homepage.
For the Chrome browser
Go to the Settings in the top right corner of the browser. Once there, go to the on-startup section. The first two options dont have any homepage whatsoever, so you can go ahead and select either one of those.

Importance Of Cybersecurity For Remote Workforces
The COVID-19 pandemic has driven the global adoption of remote work as a new, potentially transformative norm. But remote work also represents a golden opportunity for cybercriminals, who have found employees working from home, under loose supervision, to be soft targets for hacking. Hackers are using increasingly novel, sophisticated tools. But more mundane exploits, including oldschool malware and socialengineeringmethodssuch as phishing and vishing, are seeing a resurgence as remote employees or contractorspreoccupied with work and inexpert in cybersecurityprove vulnerable.
Remote employees are soft targets for hackers and cyberspies.
Mid-level employees have difficulty thinking of themselves as targets for industrial spies or state-sponsored cyberspies. Construction firms have also been targeted by hacks and ransomware attacks. The manufacturing industry, long considered lax in its cybersecurity standards in comparison to other industries, had by 2020 become the second-most targeted industry for ransomware and data-theft exploits, after financial services.
Scan Your System Immediately
This is the first line of defense. If you have an antivirus installed, scan your system immediately to check for any possible malware infections. If the infection is obvious and easily located, you can attempt a removal. If nothing is found, and you still feel somethings not right, you can run an alternative current and tested antivirus scanner.
Remember to regularly run an antivirus scan for your computer and real-time and scheduled scans for servers, and all other devices connected to it via FTP. Invest in a good malware removal software, and a server monitoring tool for real-time updates on your servers performance.
How To Scan Your Computer For Viruses
By default, Windows 10 is always scanning your PC for malware with the integrated Windows Security application, also known as Windows Defender. You can, however, perform manual scans.
On Windows 10, open your Start menu, type Security, and click the Windows Security shortcut to open it. You can also head to Settings > Update & Security > Windows Security > Open Windows Security.
To perform an anti-malware scan, click Virus & threat protection.
Click Quick Scan to scan your system for malware. Windows Security will perform a scan and give you the results. If any malware is found, it will offer to remove it from your PC automatically.
If you want a second opinionalways a good idea if youre concerned you might have malware, and your primary antivirus doesnt find anythingyou can perform a scan with a different security application, too.
We like and recommend Malwarebytes, which pairs well with Windows Security to provide an extra layer of protection for your PC. The free version of Malwarebytes will let you perform manual scans to check for viruses and other malware on your PC. The paid version adds real-time protectionbut, if youre just looking to test a computer for malware, the free version will work perfectly.
Windows 7 doesnt include built-in antivirus software. For free antivirus, you can download Microsoft Security Essentials and run a scan with it. This provides similar protection to the Windows Defender security software built into Windows 10.
