A few days ago my internet download speed slowed down almost by two thirds but my upload speed remained the same. I thought it was an ISP problem but after that I suddenly couldn't run any programs and an error messege appeared whenever I tried. I also couldn't use the Run command and use the Internet. System Restore wouldn't work when logged on too. So I used HP recovery tool, which you select to use when booting, so I was at least able to use System Restore from that tool and restored my laptop to "two days ago". OS seemed to work OK after that, except some programs which wouldn't start or work strangely. I tried to run Bitdefender Antivirus but it seemed to not work too. So I reinstalled, updated and ran a Deep System Scan but couldn't find any viruses or spyware. I also reinstalled my Ad-Aware and ran a full san with updated definitions with no threat results. Only suspicious activity I know of was a message from Ad-Watch which would pop-up now and then with "svchost.exe is trying to modify registry ..." Ad-Watch didn't show from which directory the svchost.exe was so I let it be (I always told it to block the svchost.exe). After a day I booted my computer, launched some applications and all of sudden all applications started not to open and I wasn't able to launch anything, only applications which were open before the problem started were active. Fortunately Ad-aware and Bitdefender were open and I ran a deep system scan on both of them with no results.
With no other option I ran the HP Recovery tool again and restored to "7 days ago". After the restore had completed my internet download speed had been very good for a few minutes but slowed down again. I downloaded Kaspersky Internet Security 2009 trial, updated it and run a full scan, still nothing came out. My internet speed is really slow now and I believe the above mentioned problem will start again after few days or hours.
Fortunately I found bleepingcomputer.com of which I have heard high words on other sites. I am almost sure I have an infection. Please help me get rid of it. Thank You in advance.
P.S. This problem is happenning on HP Pavilion dv2890nr running Windows Vista (Downloaded and installed all updates I believe) with KIS 2009 trial and Ad-Aware 2008 Pro (both updated).
