Computer suddenly running slow and freezing frequently..Help!?

Hi,

My computer has been running smoothly for about 4 years now. However suddenly over the last few days, it has started running extremely slow and constantly freezing to the point where the computer is unusable (am using sisters comp to write this).

My norton security is upto date, i regularly defrag etc and look after the computer.

I recently went wireless (security protected). I dont know if this has anything to do with it.

A virus scan revealed a trojan (but was only a low threat) which has been deleted but the computer is still running poorly.

Has anyone got any ideas as to what is causing this? before i reformat the computer?

Any help would be greatly apreciated!!

Thanks

Clean up all junk, remove viruses and check your hardware. This may be a number of things, including your motherboard.

I installed ZOne alrm on a computer and I wont start anymore.?

the computer had a lot of pop ups and installed Zone Alarm internet security and restarted the computer and the only that does now it doesnt want to restart. It loads the boot screen and then goes back to the beginning. I get a screen that says if I want to start up normally or with the settings it had before and select both of them and the same thing happens. What can I do to restart it?

download ccleaner.com from the internet. It's free. Then run it. It will clean and free up space on your hard drive. wipe out cookies and put things back where they belong. It will usually store itself with your recycle bin. Just clink run once a week. Also, it will tell you if there are any updates available, and they are always free to use. Great program.
My condolences on your buying Norton. Better than nothing though. Download and run CCleaner.http://www.ccleaner.com/

How do I remove a ';Your computer is infected!'; warning?

The company SPYWAREQUAKE sent me a popup ad for a spyware program and a ''free trial.'' I downloaded the free trial and at the end of the free period notified them by email that I wanted to cancel and not be billed in the future. I have not been billed and have gone into the Control Panel Add or Remove Programs and uninstalled the program. However, I get a shield with an x in the middle of my tray and every few minutes a 2'' x 2'' popup from the system tray will appear for 10-15 seconds and it has black letters on a gray background with a bright red color surrounding the gray andit says, ''Your computer is infected!'' Does anyone know how to get rid of it? I've searched for in files and folders, I've tried to uninstall it from the control panel, I've looked at the register and can't tell what the name of it is and therefor can't delete it. Now the red shield with an ''x'' is a bar above the screen and it says, ''Your current security settings put your computer at risk. Click here . . . .

ur pc is infected with mailware and spyware . trojans

you need to run the pc in safe mode run ur antivirus . spyware , antit- trojan. anti -mailware

Offensive rootkits, which are used hide malware programs and maintain an undetectable presence on an infected machine, have become the weapon of choice for virus and spyware writers and, because they often use kernel hooks to avoid detection,

What is your list of the best free security softwares?

I understand that we should not pay for the security of our computers. Many others think the same way and created free softwares like Comodo, Crawler, Javacool....e.t.c....

What do you think is the best combination of free softwares? Are you currently using them on your Windows?

What is your list of the best free security softwares?ktm

Being an IT Manager, I firmly believe you get what you pay for, PERIOD. Using a combination of freebies will cost you not a dime, but will cost you PLENTY of performance on your computer, and in many cases bring it to a standstill. The best pay AV/AS I've found, that I use on all our office machines and mine at home is BitDefender. Very reasonably priced and has been doing the right thing for us here for over a year. Doesn't weigh down your system like Norton, McAfee or Panda. BitDefender does have a freebie available, but again, you get what you pay for. Trend Micro is also decent, not slowing your computer alot, but is pretty pricey compared to BitDefender. Cheers!

You will need a REALLY FAST computer with lots of memory to follow some of these suggestions ... loading 3- 5 programs to run in the background is like putting 3-5 paper filters in your coffe maker.

I have a huge problem with my computer ever since i uninstalled a whole bunch of programs!!!?

i went away to college, and they have you install security programs on your computer. While i was at school i had to install a bunch of other things as well, i downloaded aim, and stuff like that so i could talk to my friends, adobe reader, and things like that. now im at home, and i wanted to uninstall everything that i dont use becuase my desktop looked like a mess. so i did. its currently not hooked up to any internet or anything. ever since i did that, every time i try to log on, or try to click on anything, it starts to load, but just ends up looking stuck and a blurry picture. Also the monitor goes on and off all the time! everytime i try to click on something it does that also. sometimes it will go into sleep mode and even if i move the mouse it doesnt wake up! one time a blue screen came up and was like ''if this is the first time seeing this message, restart the computer. if its not do the following.'' its a dell and windows, any suggestions would be greatly appreciated

Back up your data and reinstall Windows from the CD that should have come with your laptop. Sounds like you removed some things you shouldn't have. While it might be possible to figure them all out, and reinstall them, it probably would take a lot more time and effort.

File download from unknown zone in Internet - I am in problem after unckecking the Security message?

while attempting file download from Unknown Zone, a small yellow box comes up with 3 options 'Open' 'save' 'cancel' along-with a security caution at the end, and a checkbox(with default checkmark) containing a message 'Always ask before opening this type of files' . I am in great problem after I unckecked the checkbox. All large files with that particular extension(.csv) are opening direct on my browse. However, this unchecking has not affected opening of files with other types of extensions (.dbf etc.) in unknown zone, and they are displaying the 'warning message' as usual. Changes made in Security-Privacy-View-Display Settings etc., failed to restore Original settings for that particular type of file download. Direct downloads from UnknownZone without having a chance to Review the file is a security threat to my computer.

How can I restore back to my Original Settings ?

well there are many options. the best one would be to check system restore in control panel. and restore the os to a previous date. you can also make a disk partition and isntall another os, then tranfers your old files to the new os. Also dont mind much about that box that comes up when you try to download a file. its only a warning it doenst do anything. get a firewall and customize it to do this instead of that useless box.
