The simple answer is that SPICE component models are plain text, and you can't hide a virus or malware in text. ?No component model is ever "executed". ?They are all fed as input to the LTspice program, which interprets them as text and parses them to get the information it needs. ?Even then LTspice is always in control, doing the things it needs to do to simulate a circuit. ?The model is never "calling the shots," nor does LTspice have the capability to do much more than build waveform data and save it to its output files.
Could someone write a virus that exploits a heretofore unknown capability of LTspice to do something bad? ?I seriously doubt that it's possible, and just as unlikely that someone would know how to try.
Now, are ALL files here on this site guaranteed trustworthy? ?Here the simple answer gets more complicated. ?There are occasional Word DOC files and a few (VERY few) executable programs here, and a handful of HTML files.
This is a user-contributed forum, so yes, the possibility exists of something bad in an upload, under the guise of it being something useful.
I do not recall any incidents of malware here. ?On the other hand, Spam does rarely get through, either in messages or in the Links section, and they have all been dealt with promptly.
