Thumbnails formation and speed coming down.

i am no expert about computers and stuff like this, but my hunch is that it can be. I am also having problems with loading of pictures and videos whenever I have slow connection, and thumbnails keep appearing as a result. Also, the slowness of the processing of the pictures can be brought about the low memory available for the processing to use in loading the pictures. I have done the same thing as you are and no virus was detected by my antivirus. So I guess it is either the slow processing due to the internet speed or the slow processing of the computer itself.

hello ravi, I am sure you got the answer now. I want to thank you for this topic. now I've learned new things...

A Windows OS tracks everything you have done in your computer and it progressively slows it. Except reinstalling Windows -- or switching to Linux -- there is nothing to do to avoid it : an optimizer -- you can try Nirsoft CleanAfterMe : http://www.nirsoft.net/utils/clean_after_me.html -- or a defragmenter will not help a lot here.

Everytime I am experiencing laptop speed goes down, I execute this freeware called Advanced System Care 5 because it scans and repairs fixed problems. It is a sort of a registry boot that clears problem files but it is much better than this one. Somehow, it worked for me. I do this everytime I suspects my laptop's speed slows down. It took only 10 - 15 minutes to scan and repair files.

thumbnails never slow your computer they created by system to quick view of your pics. Cleaning of temp file etc you already done is basic job for gain some space, U can also Clear prefetch directory in window folder. most important thing how many process your computer running, can all are required, stop them change automatic to manual in service area. Secondly when u installed any software many registry entry are created and remain there even you uninstalled the software. Try for clearing unused registry entry by software. I used Norton 360 Paid antivirus included this all tools. Cost me $17 for Yr. Before it I also used free antivirus and some other optimizer tools but free version never keep you full happy.

hey some times its happens with the threats which cannot be detected by the antivirius, sometimes its happens with the pirated version on the window, please check them too.

hi rave I see you have already got a lot of good information and help just wanted to say keeping your anti virus on for long periods of time really slows down your computer. I foumd that I cou ld program my microsoft antivirus to do a complete scan one day a week while I was at lunch and my computer runs a lot faster which it should as I have Time Warner's cable internet Jack Rabbit speed. but I do find even them mylkot itself sometimes loads slow, most time med. fast and I know its not my computer as its fast on all other sites

Thumbnails are created by Windows explorer to show you those small preview pictures of image files, they are created by default (but can be completely disabled very easily). Viruses in almost every case, have nothing to do too. More common causes are primarily insufficient hardware to run advanced and newer programs, too many programs open (including those hidden running in the background), insufficient free HD space or in some cases high CPU/GPU temperatures. Just a few questions, what OS do you have? And what hardware are you using? Are you using some special, resource hungry program or many things at the same time?

Hi i use CCleaner and Spybot to clean my PC from internet remains. I do not if these programs might help you but you can try. These are freeware so you will not have to pay anything at all.
