Different examples of malware do different things, but some common things are your anti-virus software stops working, you see weird filenames with more than one filename extension, you can reach some websites, strange pop-ups and notifications - there are others, but these are pretty common indicators.

It very much depends on the virus. Your best bet is to get some kind of antivirus and do a scan if you might have one. It's better to be safe than sorry.
