1. Computer is slower than usual

Computers infected with malware run much slower than they normally would. This is because the malware runs in the background, consuming your computer’s processing power, bandwidth, and memory.

2. Unrecognized programs and processes are running

If you notice that a strange processes are running, you may want to search and identify each of them using google search. You can identify them with a utility called Windows Task Manager or in Mac OS. This lets you see each specific process and applications that are running on your system.

3. Unexpected pop-up ads are coming up

Constantly having pop-up ads appear in your web browser might mean that a malicious program got installed onto your computer. Cybercriminals use these ads to earn money through dishonest advertising and to install malware on computers. Never click on a suspicious pop-up or allow it to lure you into taking action. For example, it may ask you to pay for a program to remove a virus but may in fact do the opposite.

4. Excessive hard drive activity

An excessively active hard disk when not using your computer can be a sign your PC is infected with a virus. Keep you eye on the flashing hard drive light on the front of your computer. In addition keep your ears open for hard drive clicking sounds.

6. Anti-virus software stopped working

Some viruses are designed to disable your computer’s anti-malware protection. Having your anti-virus software stop working for no apparent reason can indicate your computer is under attack. Malware does this as a self-preservation tactic. In other words, the malware is trying to ensure that it is in control over your system and that nothing will prevent it from doing so.

7. High network utilization

If your LAN or internet connection is very active even when you’re not using it, malware may be busy sending information back and forth through this connection. Quite often there are also unneeded opened ports on your computer firewall or router.
