Any ideas? They are all files that an ancient version of Norton AntiVirus, that's now had it's definitions updated, has identified as being infected with a variety of trojans. One such torjan goes by the name of trojan.startpage. Can't say I've heard of it but for the minute I've put the associated files on the exclude list as otherwise the machine refuses to boot. I've tried the Repair option but it can't fix them.
Could someone recommend a course of action too if that's possible.
