SS Virus Removed But Still Causing Problems

On my sister's MacBook running a dual boot XP/OSX (Apple side hasn't been able to boot for a year I think), she got the System Security virus. I booted in Safe Mode and ran MalwareBytes. I also ran an Avast! scan and manually deleted files and stopped processes from running on boot. Worked like a charm, except that Internet Explorer and Firefox no longer work. I have tried complete uninstalls and reinstalls as well as changing connection settings but I'm afraid a piece of the virus is still messing with my computer. I can run both programs but they tell me the address can't be found or I'm not connected to the internet. I am still connected to the network and some programs can update themselves.

So I updated all the Java stuff and ran Hijackthis. Please note that she is running SP2 because I can't access the Windows Update site and attempts at a manual flash drive update have ended with errors.

Edit: If it matters at all, in C:/Windows/Temp there are two .DAT files that I cannot move, view, or delete: Perflib_Perfdata_9f8 and Perflib_Perfdata_47c

I'm afraid I have bad news.

Your system is infected with a polymorphic file infector called Virut. Virut is capable of infecting all the machine's executable files (.exe) and screensaver files (.scr). However, the problem is that the virus has a number of bugs in its code, and as a result, it may misinfect a proportion of executable files and therefore, the files are corrupted beyond repair. As of now, security experts suggest that a format and clean install, or destructive recovery if you have an OEM recovery partition, is the best way to clean the infection and it is the best and safest way to return the machine to its normal working state.

Backup all your documents and important items (personal data, work documents, etc) only. DO NOT backup any executable files (softwares) and screensavers (*.scr). It attempts to infect any accessed .exe or .scr files by appending itself to the executable.

Also, avoid backing up compressed files (zip/cab/rar) files that have .exe or .scr files inside them. Virut can penetrate and infect .exe files inside compressed files too.

Recent variants also modify htm, html, asp and php files.

Do not back up to another machine, as it may become compromised. Burn to DVD/CD, or to an external drive which has nothing else on it, and which you can format should it happen to become infected from the backups.
