Although many PC owners take an active interest in the safety and security of their systems, it is inevitable that at times there will be threats and infections which will manage to sneak onto healthy PCs. The case in point is Worm.Ructo.B, a worm which spreads to different systems via Windows Live Messenger. This worm is an especially dangerous infection given its vitriolic and seditious nature, and because of this users will have a tough time when trying to identify and remove Worm.Ructo.B from their systems.
Worm.Ructo.B does not make its infiltration of or presence on the system blaringly obvious to the PC owner, and will indeed try and remain completely in the background. It will further try and confuse users and security software by randomly generating and deleting files from the system. This worm is also known for lowering the security settings in Internet Explorer, in effect making it much easier for other threats and infections to gain access to the PC.
If you are undecided about the presence of Worm.Ructo.B on the system, look for the following file in your C: Drive:
If you find the above file in that location you can be sure that the system is indeed compromised by Worm.Ructo.B. Internet Explorer will also open http://www.youtube.com/watch?v=gOO_UqzEc5Y without prompt by the user. This is all irrefutable evidence of the presence of Worm.Ructo.B on the system.
At the end of the day the only way to guarantee the good working order of your system will be to invest in genuine security tools which will be able to detect and remove Worm.Ructo.B and similar threats from the system.
