About a month ago I managed to catch something really nasty which manifested itself as pop-ups and major computer slow down, especially internet.

I was using norton at the time and after repeated trips to their knowledge base eradicated everything so it would show up clean in a safe scan, norton is now using 75% of the CPU in spikes and the internet etc is slower than ever. So I then had a go at "fixing" norton including giving them money for their latest effort etc etc still slow, still sucking up the cpu.

In a fit of pique I switched to AVG which turned up 250 odd infections on its first scan (up from 0 for nortons last effort) situation has improved but comp is still not back to normal speed especially internet.

I've tried reinstalling firefox, I use AVG, adaware, regscrubxp, ccleaner, defrag etc

AVG and adaware turn up nothing worse than the occaisional tracking cookie yet something is definately not right, its a family PC and it turns out we all use the internet more than we thought and everyone's giving me a hard time because it doesnt work.

Please help, thanks.

Will

Did you follow all the suggestions in Slow Computer/Browser? Check here first; it may not be malware. There are reasons for slowness besides malware - i.e. disk fragmentation, disk errors, corrupt system files, too many startup programs, unnecessary services running, not enough RAM, dirty hardware components, etc. As your system gets older it becomes filled with more files/programs and has a natural tendency to slow down so cleaning and regular maintenance is essential.

I see you are using registry cleaners. They are extremely powerful applications. Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly can have disastrous effects on a system.

"Checking here first" :thumbsup:

Of course all these scans take hours to complete and I did do the slow computer checklist on the XP thread and didnt turn anything up.

I'll post again with an update once I've been through everything in the list

Thanks

Duly noted about the registry cleaner - was reccomended elsewhere on this site in conjunction with the ccleaner to help speed things up, I shall not use it again...

Registry cleaners can be useful when necessary to fix a specific problem. Its just that they are often misused and/or used on a routine basis when there are no particular issues going on. Then if your going to use such a tool, you should be familiar with all aspects (features) of how that cleaner works as well as an understanding of the Windows registry. Even then you still need to be careful and backup your registry before making changes.

If you don't have an understanding of the registry or the tools your using and you are not having any problems, then its best to leave the registry alone.

SuperAntiSpyware is an excellent scanner, and best of all it is free. I would install it and run a scan in Safe Mode (How to start Windows in Safe Mode), and also scan with AVG in Safe Mode (you have to update the definitions while in Normal Mode, then boot into Safe Mode to run the scans). Then I would run a couple of on-line scans such as:

Housecall
BitDefender

See if that improves things.

With respect I have done a number of safe scans and come up clean

The problem is, in a nutshell, that my PC says its clean and acts like its infected.

anything else I could do?

thanks

Check your devices in Device Manager (Start > Run > type "devmgmt.msc" (without the quotes) and press Enter). Look for any red or yellow symbols next to any of the devices.

Also, have a look in the Event Viewer for any recent errors.

To open the Event Viewer go to Start > Control Panel > Administrative Tools > Event Viewer. Alternately, go to Start > Run and type in "eventvwr.msc" (without the quotes) and press Enter.

Check in all three categories (Application, Security, and System).

If you find an error right-click on it and select properties. Copy the information in the window and post it back here. This will help us diagnose your problem. If there are lots of errors post the most recent two or three.

The "Initialization failed because the transport refused to open initial Addresses" error can often be resolved by using the

netsh winsock reset catalog

command. See this and this link for further information.

Note that resetting the Winsock using netsh winsock reset catalog command in SP2 removes all the third-party LSPs and restores Winsock to factory default setting. Existing programs that uses their own LSPs, need to be reinstalled again. Example: Google Desktop Search.

Ahem, in the absence of futher guidance.....

I ran Housecall and it came up witha bunch of stuff some of which it couldnt fix/remove.

so please forgive my previous answer, I'm going to run Bitdefender now and we'll see what else turns up.

any chance of some more help?

FYI housecall couldnt deal with XPSPYBOT (or similar it was late and of course like a dummy I didnt deal with it there and then) and couldnt fix a vulnerability in ASP.NET
