Firstly download the free version of AVG antivirus and the free version of Adaware. Run both of these and see if it helps
I downloaded the free CCleaner software and it helped me resolve an issue when Comodo Antivirus would not uninstall, but I believe I used it a little too often and now am running into many computer troubles.
I also believe I have a number of virus or trojans affecting my system. I noticed a load of programs running in my Task Manager and I began doing Google searches on them, then, my disc defrag wouldn't work; Java stopped working as well as other programs.
I have problems opening new Free downloaded programs from Downloads.com. On one program I downloaded, ProcessExplorer, I clicked on "save", then "open", nothing happens. It installs into my documents, everything I click there does nothing. The same happens with HijackThis.
I'm sure I've messed up or deleted my settings, but I'm also sure theres a bug. Everything stopped working this morning, I had to open windows in safe mode and ran CHKDSK, after that I was able to access the internet again.
I'm running on a Dell Dimension 2400, Windows XP V.2002 Service Pack 2, Pentium 4, IE 7.0, my security is CA Security package (freeware through my internet provider).
I'd like to use the Process Explorer, I'd appreciate any help you can give.
