The truth is that there’s no way to prove that your computer is absolutely clean. You may use every possible scanner or bunch of up-to-date tools, but the possibility of infection still remains. You will probably agree that no tool catches everything. So how can you be sure about your computer?
For instance, let’s take the most common symptoms of malware infection:
- warnings from your anti-malware software,
- unusual activity on your system,
- slower computer performance,
- occurrence of unauthorized remote connection,
- inappropriate internet speed,
- questionable pop-ups telling you that your computer is in danger and needs a scanner or other program you’ve never heard of,
- problems with booting or rebooting before login and etc.
The news, obviously, isn’t very exciting… But what can you do? Well, at first you should stop claiming that your PC is virus-free, and second, you should do everything to increase this likelihood greatly. Basic steps are presented below:
- install and run and anti-virus program, always check if this software is still valid and database is up-to-date,
- use only licensed software programs and don’t forget to update them (in case any vulnerabilities, discovered after purchase, will be corrected),
- chose adequate firewall settings (control the software and hardware which is using a router),
- be careful when sharing information with other computers, because one infected computer may spread its infection to others through the connection channel,
- use your PC rationally.
To sum up, no tools or safety measures can protect you from yourself. But if you follow all recommendation honestly, you will be able to say that your computer is as clean as possible.
