Experts and people who are well versed with such attacks suggest that one way to keep a check on one’s computer is to have inside-out knowledge of the functioning of the machine. Awareness about all the programs running and an update on applications and firewalls is a must for any user. While you work on safeguarding your computer, you must remember to disconnect the computer from the internet. This is done to ensure that you are the only person working on your computer at that point in time. It is also important to go through the task manager so that you can track all the running applications and programs.
After you have realized that you’ve had intruders, you need to take some immediate measures to control the damage. Once you know that an intruder had complete access to your computer, you will then have to work hard to undo the damage.
To start with, you must ensure that the anti-malware and antivirus programs on your computer are up to date. You also need to be sure that the software for virus protection is deactivated. Only after all of this will it be fine to run a scan on the full system.
During the scan you may find some suspicious things. If suspicious objects are found, you should remove them immediately. The point to remember here is that there might be a lot of hidden threats on the computer, therefore it is best to keep a close watch on all downloaded and installed items.
Just like ancient times, changing passwords is still the most effective way to protect against unauthorized access. The one thing you must remember is to remove all malware before resetting the password.
