Default Trojan Invasion

Over the weekend I got invaded by a Trojan. OK, I know that they are called Trojans because of the analogy with the wooden horse of Troy, and that it does not invade you, you have to invite it in. But, the point is, the thing got in.

It hijacked my browser homepage and put an undeletable item in my print queue so I couldn’t print anything. It may also have done other stuff I have not found about yet. I have got rid of most of it, have my browser and my printer back but I have no way of knowing how its presence will have affected Prime 95.

I keep all the Prime95 files in a separate directory, and none of the infected objects were found in there so I am reasonably confident, but obviously cannot be totally confident that the calculation of my current exponent has not been affected.

What do you guys think. Should I stop the exponent and start again (I am only 26% of the way through) or does the fact that everything gets double-checked mean that it is better to continue and hope?

It's doubtful the trojan affected your Prime95 stuff - these viruses tend to go after higher-value targets on your machine - opening backdoors, spamming addresses in your e-mail address books, etc. If it had corrupted your Prime95 savefiles, that would've been detected by the program on startup.

Its pretty safe to say, the trojan did absolutely nothing to Prime95.

To be on the safe side, check the size (and MD5, if you can) of your prime95.exe.

Or, to be even safer, download and install a fresh copy of prime95.

sarcasm.......it's a big word... a whole 3 Syllables - but take some time to try and grasp the concept. If you had've read the two posts previous to that one you would've understood - note the :) underneath? this generally indicates to irrational people like yourself that it is A JOKE........
