On my other PC, I downloaded VirtualDub Portable from portableapps.com. The first time I used it, nothing seemed wrong, but I accidentally deleted the output file so I ran the extractor (installer) a second time and Kaspersky popped up a red alert box notifying my that virtualdub was accessing a trojan.downloader (can't remember full name, sorry) somewhere within application data folder. I have made an online order to Scan with my bank card on the same day and I can't remember if it was before or after I downloaded VirtualDub. Is this anything I should be worried about / is it likely to have stolen my bank details? I'm currently restoring a HDD image from a previous date, even though Kaspersky managed to delete the trojan - just to be safe.
