infection, viruses or malicious software can compromise your pc; slowing down its
performance or disabling critical tasks. Key loggers, which are a type of spyware can
be used to steal personal information such as passwords or financial data.

at the same time can cause conflicts which can slow down the PC or they could
recognise each other as a virus. Anti virus software has a database of virus signatures
which helps it to detect threats, once detected the anti-virus program can attempt
to quarantine or remove the infection.
