What is the main reason behind getting system slower while browsing internet or opening any program?

Sunday, August 23, 2009

When we use internet or any programs like word, excel or any other programs. Then some of the file are store in cache memory and temporary folder. These store lots of file which is not necessary for us at all. So we have to delete these file frequently because these file make cause to load computer slower while we open or restart computer. For internet as well we need to delete files from the internet explorer which is located in

Internet explorer => tools => Internet options => Click on Delete cookies , Click on Delete files and Click on clear history

Note : When we delete all file some of web address store in offline folder are also deleted and those files which are stored in cache memory is also deleted. So use as per your requirement. You can only delete cookies only or files or clear history.

Role of System Recovery while scanning virus

Wednesday, August 5, 2009

If we find any viruses in our system we have to change some setting of our computers before scanning our system otherwise when we start scanning without this setting it might be possible that viruses and worms might not completely be removed because sometime in some anti-viruses when threats are detected and try to remove it. It takes backup of that file and store it in its folder. But the usual case of having this problem will be with the System Recovery because it will backup this files most of the time. Most the anti- virus warns about this information. But if it does not then we have to disable System restore before scanning our infected system.

Hacker may send pop up message which slows down our system

Hackers enjoy taunting their victim by sending lots of pop up messages and making the system slowdown. Sometime hacker even send the e-mail from our other private e-mail address to our local e-mail address. So if we receive those e-mail then we can say that incident has already occur. In some cases hacker sends message like “I know your IP address”. If these kind of message are received then it is an incident which has been occured by some hackers.

When we are downloading any free software from the web it might contain some hidden files in it which may be viruses. so be aware of those free download site and put our anti-virus up to date which will detect virus instantly and delete or disable download.

Tuesday, August 4, 2009

When system is infected with Ravmon.exe virus then if we go to the my computer and right click on any drive then small pop up window opens which include explore, search, copy, paste, properties etc. Their it must show open as well but due to infected with Ravmon.exe it does not show open list and pop up windows also shows list in different language such as chinese.

This is due to infection of Ravmon.exe.

If we want to remove this virus we can use nod32 anti-virus so that it removes this virus completely because there is link of another file as well which is Autorun.inf. Some anti-viruses does not delete this autorun.inf while nod32 delete both of them. the outcome from other anti-virus will be like, it delete Ravmon.exe but doesnot delete Autorun.inf so when we scan with other anti-virus it does not show any viruses but if we right click on any drive same thing as above like open does not show.

For this reason if we want to completely delete it we have to do it manually like this

=> Click on start menu

=> Clik on Run

=> type CMD then Press enter

=> It opens new dos prompt window

=> Type ATTRIB -H -R -S AUTORUN.INF then press enter

=>Type del autorun.inf then press enter

Now the virus is completely removed and your right click on drive will show open list and won't show chinese language as well.
