We present you 10 ways to know
if your computer is infected with viruses based on 10 symptoms to identify the
failures. Viruses can alter the proper functioning of computers and these
alterations can be identified. Learn how to know if your pc is infected.
The companies, focused on computer
security or antivirus,
presented a set of symptoms so that they can indicate how your computer is
being a victim of malicious code such as viruses.
Here are the 10 characteristics to consider:
1. The fan starts at full speed when the computer is idle: This may indicate that a program is running without the
user's knowledge and that a considerable amount of resources are being used. Of
course, this could also be a product of Microsoft's installation of updates,
for example. Another problem that can cause the fan to work is excessive dirt
on the computer or a failing CPU fan.
2. Your computer takes a long time to shut down, or does
not shut down properly: Malware often has
errors that can cause a variety of symptoms, including a long shutdown or
failure. Unfortunately, operating system errors or conflicts with legitimate
programs can also cause the same symptom.
3. Observe content on your Facebook wall that you have not
submitted: There are some other reasons
other than malware or unauthorized access to the account for this problem to
appear. If you see what happens, you should definitely change your password and
make sure that the system is not infected. Ideally, make sure your computer is
free of malware before changing your password and not using your Facebook
password on multiple different sites.
4. Applications are very slow: This can happen because hidden programs are using a large
amount of computer resources. But it could also be caused by other problems.
5. Unable to download operating system updates: This is a symptom that cannot be ignored. Even if it's not
being caused by a bot or other malware, if you don't keep your antivirus software
up-to-date, your system will get infected.
6. Unable to download antivirus updates or visit vendor
websites: Malware often tries to
prevent antivirus or
security solutions from being installed or running. The inability to update the
antivirus or visit the manufacturer's website is a very strong indicator of the
presence of malicious code.
7. Internet access is very slow: If a bot is running on the system to, for example, send
large amounts of spam, carry out an attack against other computers or upload /
download large amounts of data, it can cause access the Internet is very slow.
8. Your friends and family have received emails that you
did not send: This could be a sign of a bot
or other malware, or that your webmail account has been compromised by an
attacker.
9. Pop-up windows and advertisements open, even when you're
not using a web browser: While this is a
classic sign of adware, bots can install this malicious program on your
computer. You should definitely address this issue.
10. Windows Task Manager displays programs with strange
names or descriptions: Using Task Manager
requires some skill and research. Sometimes legitimate software can use strange
names. An entry in the Task Manager is not sufficient to identify a program as
harmful. While it can help find malicious software, additional steps must be
taken to validate the results. Deleting processes, files or registry entries
just because it is suspected to be a bot or other malware may result in the
computer not even starting up. Be very careful when making assumptions and taking
action on them.
