Free PC ‘scan and repair’ software will perform the following actions to judge if you are safe from viruses. It will make a check for self executing malware. Many viruses are self executing programs and also they start replicating themselves or some other folders in the PC. Other than these services, a free PC scan and repair program offers regular check ups to see if your PC is at a threat of an intruder attack. An intruder attack can be in the form of malicious software and Trojan horses. These programs are devised by hackers and may enter you computer system by an infected USB or hard drive or by an email attachment.
